Design of Seismic Isolated Building with StaggeredPrecast Concrete Wall
This building is a nine-story office building located in the Italian Town in Shiodome, Tokyo. In this area, the townscape is designed based on an Italian theme, and the building façade was required to be an expression of masonry construction. In addition, the client demanded a balance between office space flexibility and seismic safety. In order to solve these problems, a seismically isolated building with a staggered precast concrete wall system was proposed. The system can provide the flexibility of interior spaces, simplification of construction, and great horizontal stiffness, such that seismic action to the structure above the seismic isolators could be minimized. To investigate the structural properties of the system, experiments using scaled test specimens were carried out with varying the vertical load acting on the wall. The experimental results showed that the load capacity of the system could be evaluated from the sum of friction force on the connection area and dowel capacity of reinforcement bars. Non-linear finite element analysis was conducted, and the analysis was validated by the experimental results. The analytical results also supported the bearing mechanism.
