| 摘 要： | 为研究地震作用下不同楼板厚度对带转换层的高层建筑结构抗震性能的影响,文中采用反应谱法对楼板厚度为100、120、140、160mm的四种结构进行自振周期、振型、剪力和地震力对比分析。结果表明,楼板厚度为100mm和120mm的结构自振周期不能满足规范要求,结构的剪力和地震力与楼板厚度成正比关系。通过对比可知,工程结构中楼板厚度选用140mm可以满足抗震要求,整体抗震性能良好,且经济实惠。

| Abstract: | In order to study the influence of different floor thickness on the seismic performance of tall buildings with transfer stories under earthquake, the response spectrum method is used to compare the natural vibration period, mode shape, shear force and seismic force of four structures with floor thickness of 100 mm, 120 mm, 140 mm and 160 mm. The results show that the natural vibration period of the structure with slab thickness 100 mm and 120 mmcannot meet the requirements of the code, and the shear force and seismic force of the structure are proportional to the slab thickness. Through comparison, 140 mm slab thickness can meet the seismic requirements in engineering structure, and the overall seismic performance is better and more economical. |
