摘要

北京将台冬季花园采用复杂的杂交结构体系,其中屋面网壳部分可以视作拱壳杂交结构.近年来世界各地地震的频发使得空间结构的动力稳定问题亟待解决.本文对冬季花园建立了修正的有限元模型,通过不同峰值加速度地震作用下的非线性动力时程分析,研究了该模型在一条天然地震波作用下的动力稳定性能.结果表明,结构的动力稳定临界荷载超过了规范规定的最大值,可以认为结构的动力稳定性良好.
Beijing Jiangtai Winter Garden applies complex hybrid structural system,in which the latticed shell can be seen as arch-reticulated shell hybrid structure.The frequent earthquake recently in the world makes the research on dynamic stability of spatial structures extremely urgent.In this paper,the refined finite element model is established,and then its dynamic stability under one natural seismic wave is studied by nonlinear dynamic time-history analysis under the seismic action with different peak accelerations.The results show that the critical load for dynamic stability is greater than the maximum value in the specification.Thus the structure has good dynamic stability.
