Shaking Table Tests on Earthquake Response Characterization of a Complex Museum Isolated Structure in High Intensity Area

摘要: Owing to special functional requirements of museum, such as great space and story height for exhibitions, large floor slab openings in plan long span truss elevation are becoming increasingly considered museum design, which leads challenges structural safety. The aseismic performance an isolated structure high earthquake intensity regions was thus studied because its complexity irregularity. In order observe the seismic characteristics verify isolation effect, shaking table tests a 1/30-scale model with without base bearings have been carried out under minor, moderate, major earthquakes. experimental results show that dynamic effect stable storey peak acceleration responses superstructure less than fixed structure. Storey drifts meet required limits stipulated Chinese design code torsion not remarkable. It is suggested performances complex structures effectively improved use.
