We studied on the reinforcement and application range of the method, which gave the following achievements; i) the current design method can provide sufficient reinforcement even if the range of reinforcement was changed, ii) we confirmed the reinforcement effect of this reinforcement design with different web-thickness ratio and iii) the reinforced beams which reduced the initial axial force of high-strength bolts had the same yield stress as the beams which satisfied design condition..
2.	Shintaro MATSUO, Ryu HIGUCHI, Nobuyuki YASUI, STUDY ON SIMPLIFIED REINFORCEMENT METHOD FOR WIDE FLANGE BEAMS WITH WEB OPENING, 12th Pacific Structural Steel Conference (PSSC'19), 12, 3-4-3, 2019.11, This paper presents the study on perforated wide flange beams reinforced with two steel plates connecting by four high strength bolts. 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..

4.	MOU Ben, 松尾真太朗, 段差を有する外ダイアフラム形式コンクリート充填角形鋼管柱梁接合部パネルに関する解析的研究, 都市・建築学研究 : 九州大学大学院人間環境学研究院紀要, 28, 79-94, 2015.07, This paper presents an analytical study on offset H-shaped steel beam to square concrete filled steel tubular column connection panels with exterior diaphragms. 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 plastic strength of panel is proposed based on two collapse mechanisms of the connection panels. One of the mechanisms is only panel yielding type which is the same as the standard panel. The other is a mechanism by a combination of yielding in some parts such as panels, exterior diaphragms and column tube wall. In order to confirm the applicability of the strength, cyclic loading tests of cruciform subassemblages were conducted. As a result, the strength and assumed collapse mechanisms were in good agreement with the test results..

5.	Shintaro MATSUO, Takuro OYAMADA, Bi-axial Loading Tests of Beam-to-Column Connection with Exterior Diaphragms, 7th International Symposium on Steel Structures (ISSS-2013), 2013.11, Exterior diaphragm type connection, which does not require full penetration weld, is a rational method of connection between beams and columns in terms of high reliability for its seismic performance. All of previous studies on the connection targeted one-direction loading, and the design method has been established. On the other hand, there could be the case that structural designers are required to assume the connections to be input from two perpendicular directions. In this paper, a systematic cyclic loading tests of beam-to-column connection with exterior diaphragms was conducted in order to confirm the effects of various parameters on the connections under two-direction loading. As a result, it mainly revealed that both yield and plastic strength of the connection under bi-axial loading decreased relative to those under one-direction loading..
