This revised course provides in-depth video lectures that explore various concepts in architecture and structural design. These lectures are complemented by detailed articles that offer additional resources for further study. A specific focus of the course is on modern approaches to seismic design and retrofitting, using case studies of unique campus buildings located in Tokyo.
The course begins by tracing the evolution of structural design, starting with traditional timber buildings and progressing to the advent of the first steel high-rise structures. It also delves into the influence of the metabolism movement and the development of modern spatial structures in Japan. Concepts such as “Integrated Facade Engineering” and “Grid-skin structures” are thoroughly discussed and exemplified through case studies of Tokyo-Tech campus buildings. These case studies highlight how seismic performance was enhanced sustainably, while considering environmental performance and aesthetics. Furthermore, immersive 360-degree videos of Tokyo Tech buildings are provided to offer learners a captivating experience.
The course covers the application of the grid-skin concept to reinforced concrete buildings, including the use of shear walls and a two-layer framing system. It explores modern response control strategies aimed at achieving immediate occupancy after an earthquake, such as rocking frame systems and seismic isolation in steel buildings. Practical considerations for implementing these systems are explained through the design of campus buildings. Additionally, the course delves into grid shell systems and their unique seismic response characteristics. It also examines the challenges and technical complexities involved in designing lightweight roofs, using the example of a metro station near the campus.
Lastly, the course emphasizes the importance of collaboration between structural engineers and architects. This is underscored through a series of interviews featuring Prof. L. Stalder from ETH Zurich, Prof. T. Takeuchi, and Prof. Y. Tsukamoto from Tokyo Tech, shedding light on the significance of this collaborative relationship.
