In architectural and structural design, computational methods have transformed the conceptual phase, allowing the exploration of diverse and efficient solutions. This paper introduces a new framework that integrates shape grammar, genetic algorithms, and clustering techniques to optimize structural designs in the early stages of architectural workflows. Unlike traditional optimization methods that aim for a single optimal solution, this approach generates multiple rational design options, balancing structural performance, aesthetics, and project constraints. Shape grammar effectively manages complex topologies with intuitive inputs, enabling designers to create varied structural forms while understanding the underlying rules and processes. Algorithmically, shape grammar offers significant design variety while maintaining designer control and insight into each configuration’s production. This research focuses on developing a tool for designing 2D trusses and frame systems, with the aim of creating a functional prototype and verifying its performance through a case study. The method uses shape grammar for initial topologies, clustering algorithms to group similar designs, and genetic algorithms to refine and optimize each cluster. This ensures efficient and diverse designs, providing a strong foundation for future developments. The framework’s effectiveness is demonstrated in a case study of a simplified large-scale convention hall, where these computational techniques generate innovative structural layouts. The results show the framework’s ability to produce diverse designs meeting architectural and structural needs, offering advantages over traditional parametric design. This research contributes to architectural and structural design by providing a powerful tool for early design stages, where multiple options are crucial. The framework enhances the creative potential and aligns with the requirements of structural engineering, such as safety and performance. By promoting efficiency, diversity, and adaptability, this approach can transform the way architects and engineers tackle complex design challenges, leading to more innovative building practices.

Architectural forms are crafted by designers to meet various constraints, including planning, structural integrity, HVAC systems, and regulatory compliance. Structural elements not only ensure building safety but also contribute to the architectural form itself. As the efficient use of limited material resources becomes increasingly critical, structural optimization emerges as a key factor in balancing these demands. However, topology optimization remains somewhat underutilized in architectural structures, leading to limited exploration and application in design. This work introduces a method that combines Shape Grammar with genetic algorithms to diversify architectural design through a clustering approach, incorporating metrics from topology and shape. The proposed framework supports diversified structural optimization, balancing form generation with multi-objective fitness evaluation to give architects a robust tool for exploring a wide array of design possibilities. Ultimately, this approach encourages innovation and efficiency by providing architects with the means to create resource-effective building structures that align with both structural and aesthetic objectives, contributing to more sustainable and inventive architectural solutions.

This paper present the results of vibration measurement on four Stave Churches in Norway. The study was realized by the joint research team from Norway and Japan. The two countries share important characteristics from the perspective of architecture: the richness in timber resources, technological advancement in timber engineering and the existence of ancient architectural heritage of timber post and beam construction. Four Stave churches in Norway were investigated through multiple monitoring; vibration, temperature, humidity, moisture content measurements and 3D scanning. Fromthese results the application to structural health monitoring on timber architectural heritage is discussed.

Structural optimization has gained popularity in modern structural design, helping to reduce material consumption while maintaining the structural performance of buildings. This process also significantly influences the architectural appearance, affecting various aspects such as cross-section sizing, structural forms, and the layout of structural members. Beyond minimizing materials or costs, structural optimization can serve as a powerful tool for making architecture more visually appealing. However, with the wide variety of structural optimization methods proposed, gaining a comprehensive overview has become challenging. To address this, a systematic mapping study has been conducted, focusing on methods introduced over the past decade. The relevant journal articles are categorized based on several factors, including types of optimization, materials used, structural typologies, areas of application, and optimization objectives. The results of this study provide both a broad overview of recent developments in structural optimization and valuable insights into research-rich and under-explored areas. Moreover, the paper discusses which types of structural optimization are more relevant when applied as part of the architectural design process. It is suggested that future research should focus on identifying gaps and challenges in effectively applying structural optimization to architectural design, thus enhancing both efficiency and aesthetic potential.
