摘要
昆明万达广场双塔在建至主体结构高度为180 m时发生地震。地震中,顶部结构以及施工电梯都发生大幅度晃动。以昆明万达广场双塔作为依托,通过有限元分析软件分析附墙架在地震作用下不同工况的地震响应,发现当吊笼满载处于中部时附墙架杆件处于最不利状态。但在多遇地震与设防地震作用下,附墙架仍能正常工作,罕遇地震下附墙架底部部分破坏。
When the twin towers of Kunming Wanda Plaza were under construction at a height of 180m the earthquake coming. In the earthquake, the top structure and construction elevator have been shaking. Based on the twin tower of Wanda Plaza in Kunming, the seismic response of the attached wall frame under the earthquake action is analyzed by the software of finite element analysis. It is in the most unfavorable condition when the hanging cage is loaded in the middle. However, under the influence of frequent earthquake and design earthquake, the attached wall frame still works normally. In the rare occurrence earthquake, the bottom part of the wall attaching frame was damaged.
