Abstract:Dynamic characteristics and seismic response under the seismic actions of two typical multi-tower structures were analyzed and compared with mechanical characteristics of the single-tower model. Meanwhile, slab stress analysis and temperature effect analysis of complex connection parts of the enlarged base were carried out. The dynamic characteristics of multi-tower structures, the seismic shear force transmission law between tower and podium, and the influence on floor stress distribution under different conditions were obtained. And some effective seismic structural measures were proposed to strengthen the structure.

Keywords:multi-tower structure with an enlarged base； dynamic characteristic； seismic response； temperature effect analysis
