For this purpose, an experiment was conducted to apply a constant axial force and cyclic horizontal force to the top of the CFT column. The experimental parameters were axial force ratio, displacement amplitude and corner weld strength. As a result, each behavior up to deterioration of the member under high axial force ratio of 0.5 or more were obtained, and the low-cycle fatigue characteristics of CFT column with ultra-high strength steel were clarified.. |

Experimental parameters include strength of the weld metal at corner joint, width-to-thickness ratio, panel aspect ratio and others. Based on the results, it is revealed that a CFT panel assembled by undermatched welds has the sufficient performance for practical use. Furthermore, the shear strength equations, which can evaluate the effect of the weld metal strength at corner joints of panel, were proposed.. |

column connections with exterior diaphragms under cyclic load, basing on the experimental research by frame
experiments including 6 specimens. An FEM analysis including specimens with the same parameters and
eccentricity rates of 0, 0.05, 0.075,0.125,0.175,0.2 and 0.25 is carried out to study on the influence on the failure
mode and yield strength of connections caused by the eccentricity. According to the experimental and analytical
results, even specimens with eccentricity of 0.25 showed good seismic behavior. Finally, according to the result of
the regression, the influence of eccentricity turned out to cause a linear decrease of yield strength, but strength of
a connection with small eccentricity may not decrease due to the influence of its shape of diaphragm.. |

An FEM analysis on all specimens in the experiment as well as 4 specimens with a rate of eccentricity of 12.5% have also been contained. According to the experimental and analytical results, the eccentricity has a significant influence on the specimens’ yield strength as well as on their failure modes, which is considered to be contributed by the fact that the interior side of the diaphragm did not yield totally when the specimens’ showed characteristics of yielding. Finally, the rate of load redistribution can be considered as a stable parameter to show the influence of eccentricity rates on the load distribution.. |

In the previous research, we proposed reinforcement design method and conducted monotonic loading test. As a result, fundamental structural performance and reinforcement effect for the reinforced specimen were confirmed, and validity of the proposed design method has been revealed. On the other hand, from the experimental results, the fact that there is possibility of reduction of the design stress on reinforcing plates calculated by the proposed design method was also confirmed. In this paper, the mechanical behavior under cyclic loading has been investigated taking several factors related to reinforcement design such as initial bolt clamping force or strength of reinforcing plates. From this test, it has been revealed that this reinforcement method is also effective for perforated beams under cyclic loading, and the experimental variables had small influence on the behavior of the specimens.. |

This research focuses on the full plastic strength and collapse mechanisms of the offset beam-to-CFT column connection panels, and investigates the influence of difference in beam depth and width to thickness ratio on the elasto-plastic behaviors of the offset beam-to-CFT column connection panels. The feasibility of analytical models generated by MSC. Marc 2012 is verified by a set of experimental results presented in the companion paper. Parameters used in this analytical study includes: differences in beam depths, width to thickness ratio and loading directions. FEM results suggest that the assumed collapse mechanisms can predict the failure modes of FEM models reasonably. Owing to overlooking confined effect by steel tubes on concrete panels, the proposed formulae underestimated the full plastic shear strength of the offset panels. On the basis of experimental and analytical results, an enhancement coefficient formula is proposed, which is derived from regression analysis taking the effect of width to thickness ratio of steel tubes and beam depth ratio into consideration.. |

The main objective of this research is to establish the plastic strength calculation method for the panels based on the limit analysis. Four cruciform subassemblages are tested under the cyclic and monotonic loading in order to obtain fundamental data for the collapse mechanism of the panels. The plastic strength calculation method is proposed and the accuracy of the method is demonstrated in comparison with the experimental results. Major findings are as follows: I) the assumed collapse mechanisms coincide with the experimental results, 2) the proposed formulae underestimate the experimental strength of the connection panels.. |

This paper presents the behavior of offset beam-to-column connection panels with exterior diaphragms. The plastic strength is proposed based on two collapse mechanisms. One mechanism is only panel yielding type. The other is a mechanism by a combination of yielding in some elements. The yield strength is derived from yielding of the panel, which is connected by beams in both sides. To confirm the applicability of the strength, tests of cruciform subassemblages were conducted. As a result, the strength could be properly evaluated by the proposed formulae, and the characteristics of panels have been stable up to large deformation.. |

Although the maximum velocity of Tsunami might be estimated as 15m/s in typical seashore, it may be thought that around 7m/second is the maximum velocity of the flotsam in inland. The impact velocity of falling weight is proportional to the square root of the falling height of the weight, so that the maximum falling height in this test is determined as 2.5m corresponding to the velocity of 7m/s. Another four specimens were also conducted under static condition which are the standard references to be compared with the specimens subjected to impact loads. The specimens are simply-supported beams, and the impact loads or static loads concentrically and vertically applies to the mid-span of the beams. The test specimens are circular and square CFT specimens and circular and square vacant steel tubular specimens. The increase of heaviness and velocity of the weight increase the plastic energy dissipation and the input energy for specimens. As the result of impact loading test, the CFT specimens could sustain much higher levels of the heaviness and velocity of falling weight than those of vacant steel tubular specimens.. |

The stress-strain models for above components by considering strength deterioration are simplified as to analyze steel and CFT frames subjected to ground motions. The model consists of an elastic-plastic curve up to the peak and a bi-linear after the peak which expresses the strength deterioration by negative slopes. The characteristic parameters of the stress-strain models for in-filled concrete and steel tubes are calibrated by comparing the component test results and the corresponding analytical results, and the proposed formulae for the deteriorating models of HST and CFT columns can accurately simulate the strength, stiffness and deterioration after local-failures.. |

Although various constitutive models for reinforced concrete components and steel components have been proposed, the ability of above models to capture strength and stiffness deterioration has not been fully calibrated. In this paper, comprehensive calibration and validation of the models of RC components and H-shaped steel components incorporating the strength, the ductility and the deterioration of strength and stiffness after the peaks are conducted, in order to support the prediction on the collapse resisting capacity of existing RC and steel high-rise moment resisting frame buildings. The effects of loading procedure on the strength, ductility and deterioration are investigated by comparing those of models to the experimental database. According to the calibration results, the deviation dispersion of the components under cyclic loadings is observed more widely than that of the components under uniaxial compression, since that the deterioration induced by cyclic loadings is more complex than the one of under pure uniaxial compression. Besides, the uncertainty of the post-peak deterioration of the hysteretic curves under cyclic loadings is larger than that of peak point. H-shaped steel components can be simulated more accurately than RC components for both peak point and post-peak deterioration, due to the complexity of the RC components that increase the uncertainty of the mechanical behaviour of confined concrete and steel reinforcement. The models for RC components and H-shaped steel components may have enough accuracy to predict the strength, ductility and deterioration, and further to be utilized in the collapse analysis of RC and steel high-rise moment-resisting frame buildings, respectively.. |

The effect of strength and stiffness deterioration of the components on the seismic performance and collapse capacity of existing RC high-rise moment-resisting frames (MRF) is addressed in this paper. According to time history incremental dynamic analysis (IDA) on RC high-rise MRF models incorporating various deterioration levels, significant influences on seismic responses and collapse criteria are obtained. The aleatory uncertainty (record-to-record variability) could not be considered with one-dimension that is based on an assumption that the collapse capacity is judged based on a constant engineering demand parameter for a certain structure, but needs to be considered on two-dimensions of intensity measure and earthquake demand parameter (intensity measure (IM), engineering demand parameter (EDP)). As one parameter of the epistemic uncertainty, strength and stiffness deterioration of RC component clearly shows primary influence on collapse criteria of RC high-rise MRF models, and for the method of IDA, intellective process that increment should be decreased when IM increases at a sensitive level.

It is well known that frames designed with weak beam strong column type mechanism show high ductility behavior, but the energy absorption capacity at the deformation level considered in the structural design process has not been discussed very well. In this paper, the energy absorption at the maximum drift angle of 0.02rad was investigated based on Monte Carlo simulation under the static load condition. The analysis parameters are the number of stories, the number of spans and column overdesign factor (COF). Some conclusions obtained by this study are summarized as follows. 1) Average value, 1% lower limit value and 5% lower limit value of the energy absorption increase by controlling the range of randomness of member yield stress, and 2) the increasing percentage is positively correlated with the number of stories. 3) COF can be made smaller than basic frames' COF by controlling the range of randomness of member yield stress, especially with large number of stories and high value COF.. |

Because the shear force that is attributable to higher mode responses concentrates on wall part, it is vital to predict higher mode response for the desirable design of EDSWs or wall-frame system including EDSWs.
The authors proposed the prediction of maximum earthquake response story shear not performing dynamic analysis but only performing static analysis by converting a multi-story building into equivalent single degree of freedom system, which can be applied to the Capacity Spectrum Method.. |

The base plate and anchor bolts are omitted in this CFTR column base, but the high strength reinforcements are inserted from the CFT column to the RC foundation. A total of three specimens was fabricated. The parameter for the study is the axial force ratio (0, 0.25, 0.50). The specimens were tested under the horizontal cyclic lateral load while subjected to a constant axial load. The mechanical behaviors of the column bases are investigated. The test results indicate that the non base-plate CFTR column bases have excellent seismic performances and are applicable in the practical structural design.. |

This structural system comprises Energy Dissipation Structural Walls (EDSWs) as the interior tube and Spandrel Wall Frame (SWF) as the exterior tube. The hysteretic behavior of EDSWs and SWF have been experimentally investigated and reported elsewhere. They indicated a stable elasto-plastic manner under cyclic lateral loading, and had an ample energy dissipation capacity. In order to establish a reliable performance-based seismic design method for DTHS, a further investigation of overall building through an analytical study is needed. Three building models, 3-story, 6-story, and 12-story are simulated by a frame analysis method. The structural behaviors of DTHS are investigated by performing static and dynamic response analyses. It is proved that high-rise building model utilizing proposed structural system is an effective structural system for DTHS, in which overturning moment dominates rather than shear, which is desirable in the view point of structural design. Application in low-rise building is proved also as an effective method to increase the structural performance of DTHS even though the design strength is set slightly larger than the value for controlling the deformation in high-rise building.. |

Local buckling and stiffness degradation are considered for steel model, various simplified analytical models of confined concrete are adopted to verify the accuracy of simulations. Comparison results indicate that steel model adopted in analysis program can accurately perform the local buckling and degradation of steel tube. After comparing different types of confined concrete model, the strength degradation of concrete in circular steel tube could be ignored because of high-level confinement effect, while the strength degradation of the concrete in square steel tube should be considered contrarily. Furthermore, the simplified model based on Sakino & Sun's proposal has the best accuracy on predicting the post-peak degradation behavior of square concrete filled steel tubes.. |

In order to verify the validity of the derived collapse load, component tests of the connections were conducted. Major findings obtained from tests are summarized as follows: (1) the yield strength obtained from the tests was about 80 to 90% of the calculated collapse loads, (2) the local deformation of the circular tube column that corresponds to the calculated collapse load is small enough for the yield strength, (3) the derived collapse load formula which is considering the shape of the connections correlated well with the test results, and captured the trend in a reasonable manner, (4) the maximum strength obtained from the tests was about 110 to 120% of the calculated maximum loads.. |

The authors have presented strength calculation formulae for interior columns, and it is possible to derive strength calculation formulae for exterior columns in the same way. For the perpose of comfirming the validity of the formulae, we performed monotonic tensile loading tests for beam-to-column connections. Major findings from the tests are summarized as follows: (1) the calculated values of the yield strength agreed well with the experimental results, (2) although the calculated values of the ultimate strength were about 45～70% of the experimental results, deformation of column tube walls was not very large.. |

Cyclic loading tests of beam-column subassemblages for interior columns were conducted in order to verify the validity of the proposed design method, and elasto-plastic behaviors of beam-column subassemblages for exterior column or concrete filled tube column were investigated. The test results reveal that the design method is valid. Stiffness of beams with exterior diaphragms can be properly predicted by assuming that beams are connected rigidly to columns. Deformation capacities of specimens whose beams are connected to exterior diaphragms with high-strength bolts are substantially larger than that of the specimen that beam flanges and exterior diaphragms are welded.. |
