The lab uses mechanics and computers to optimize the form and structure of buildings.
AboutAbout the lab
Designing building structures with mechanics and computation
The Architectural Structures Lab studies the behavior of building structures on the basis of mechanics and computational engineering, and develops optimal design methods.
Technology is needed that keeps costs and materials as low as possible while ensuring only as much safety and functionality as necessary.
The lab combines the latest information technologies such as AI with theories of mechanics and mathematics to propose methods for designing high-performance buildings, including considerations of aesthetics and ease of construction.
Lecturer Hayashi's lab also studies design methods based on new computational techniques, such as structural optimization and design that takes ease of construction into account.
Key terms
- Optimization methods
- Computational methods for finding the best shape or layout under conditions such as strength and cost
- Tensegrity
- A structure that keeps its shape by balancing members in tension and members in compression
- Vibration control devices
- Devices attached to a building to reduce shaking from earthquakes and wind
ResearchResearch themes
The lab studies the behavior and properties of building structures up to collapse, and builds theoretical foundations for design methods that rationally achieve the required structural performance. It is establishing new design methods for membrane structures, tensegrity structures, and vibration control devices.
*Illustrative imageDesign Theory for Spatial Structures and Tension Structures
Based on mechanical theory and optimization methods, the lab studies methods for designing building structures that are optimal not only in structural performance and economy but also from the standpoints of architectural design and construction. It also covers membrane structures, deployable structures, free-form shells, and the placement of devices that reduce vibration.
*Illustrative imageHow Buildings Collapse and Developing Vibration Control Devices
The lab uses detailed finite element analysis to clarify how buildings progressively collapse in earthquakes. It simulates the shaking of whole buildings and of their parts equipped with new devices, and develops numerical experiment frameworks for designing new vibration control devices.
*Illustrative imageAssessing Building Soundness Through Vibration and Light
The lab proposes methods for assessing the structural soundness of buildings based on vibration measurements. It is also developing a system, based on optical measurements, that immediately judges whether a building is dangerous after a disaster.
*Illustrative imageSupporting Structural Design with AI
The lab develops methods for creative architectural and structural design using new computational techniques. It builds dedicated AI models that take the particular characteristics of structural design into account, aiming to efficiently produce high-quality designs with far less computation than general-purpose AI.
