结合某实际工程,对大底盘塔楼偏置结构裙房与塔楼之间设缝分开与否两种模型塔楼部分结构进行了大震作用下结构性能对比分析,并对两种模型的材料用量进行统计分析。分析结果表明,此类结构体系受力复杂,裙房上部塔楼墙肢损伤范围较大,且材料用量明显大于常规结构体系。分析结果对结构设计具有较高的参考价值。 Combining with a practical project, the structural performance of some structures of two model tower structures with or without crevice between the large chassis base offset structure podium and the tower was compared and analyzed, and the material consumption of the two models were calculated analysis. The analysis results show that the structure of this kind of system is complicated and the damage of the wall and limbs in the upper part of the podium is large, and the amount of material used is obviously larger than that of the conventional structural system. The result of the analysis has a high reference value to the structural design.
