大底盘双塔结构是近年来工程中广泛应用的一种结构形式，其结构的抗震性能有其自身的特殊性和复杂性。目前国内对于此类复杂高层建筑，往往只专注于对其抗震性能的研究，对结构温度应力的考虑则没有引起足够的重视。结构整体在不同温度场的作用下，底盘大面积的混凝土楼板必定是受温度影响最显著的结构构件之一。但在具体设计中，无论是专用计算程序，还是主流的结构设计软件，都没有对大底盘楼板做进一步定量的分析。针对上述问题，本文通过有限元软件SAP2000建模对考虑温度和地震作用下的某大底盘多塔结构进行了反应谱分析，定量地分析了温度作用对大底盘楼板的内力分布和抗震性能的影响。

Two-tower structure with enlarged base is widely applied in practical engineering .The aseis-mic behavior has its own particularity and complexity .The currently study on two-tower structure with enlarged base only focused on the aseismic behavior and the consideration of the temperature stress was rarely taken into account .In uniform temperature field , an enlarged concrete base is definitely one of the most significant member affected by temperature .But in the concrete design , no matter a special computer program or the main structure design software , further quantitative analysis on the enlarged base was not taken .To address the above problem , the aseismic behavior of structure under the combined effect of temperature and seismic action was discussed un -der response spectrum analysis using the finite element analysis software SAP 2000 .The distribution of internal force and aseismic performance of the slab under temperature effect were analyzed .
