Research on Structural Design of an Isolated High-Rise Building with Enlarged Base and Multiple Tower Layer in High-Intensity Area

In the high intensity areas, application of interlayer spacing technology can achieve unity quality and seismic performance high-rise buildings with enlarged base multiple tower layers. Through comparison analysis structural schemes an tower-layer building, ultimate isolation scheme was adopted, its response were analyzed studied. The results show that overall effect story technique is good, which greatly reduce response, effective means to improve safety structure. Considering characteristics project, improvement economy use in structure high-intensity region optimal scheme. Finally, several key technical issues such as combined additional bending moment isolator tensile device discussed, provide some references for similar engineering practices.
