Abstract:In order to achieve the harmonization of the quality of the building and the seismic performance, it is an effective solution to adopt the story isolation technique in the large chassis and multiple tower-layer high-rise building structure in high intensity region. Through the comparison and analysis of the structural schemes of a large chassis multiple tower-layer high-rise building, the ultimate seismic isolation scheme was adopted, and its seismic response and seismic performance were analyzed and studied. The results show that the overall seismic isolation effect of the story isolation technique is good, which can greatly reduce the seismic response, and is an effective means to improve the seismic safety of the structure; Considering the structural characteristics of the project, the improvement of the economy and the quality of the building, the use of story isolation technique in the large chassis multiple tower-layer structure in the high intensity region is an optimal scheme; Finally, several key technical issues such as the combined seismic isolation scheme of large chassis story isolation technique, the additional bending moment of the isolator, and the tensile device of the isolator were discussed, which can provide reference for similar engineering practices.
Keywords:high intensity region； large chassis and multiple tower-layer structure； high-rise building； story isolation technique
