摘　　要：大底盘多塔结构的大底盘作为上部塔楼的嵌固层,有超长的平面尺寸,在地震和温度作用下平面受力状况复杂。文章主要介绍了杭州某大底盘多塔结构,通过有限元分析分别研究了在地震和温度作用下大底盘楼板的应力大小和分布规律。分析结果表明地震作用下裙房屋面楼板作为塔楼的嵌固楼层整体应力水平最高,而温度作用下二层楼板影响最大,往上逐渐减弱。针对不同工况下大底盘楼板的关键部位提出了相应的加强措施建议。The base of a large chassis multi-tower structure,due to its role as the embedded layer for the upper towers and its oversized plan dimensions besides,experiences complex in-plane stress conditions under the effects of earthquakes and temperature changes.This paper mainly introduces the stress and distribution of the floor of a large chassis multi-tower structure in Hangzhou under the action of earthquake and temperature by using finite element analysis method.The analysis results show that the stress level of the podium roof floor as the embedded floor of the tower is the highest under the earthquake action,and the influence of the second floor under the temperature effect is the greatest,gradually decreasing upwards.This paper also puts forward corresponding strengthening measures for the key parts of the floor of the large chassis under different working conditions.
