摘要
针对某大跨度可开合空间网架屋盖,根据开启方式不同,结构基本状态共6种,结构处于任何状态时都有可能遭遇地震作用。对结构多种基本状态的抗震性能及地震作用下的抗连续倒塌性能进行分析。采用反应谱法对不同状态结构在地震作用下的响应进行计算,确定开合屋盖最不利状态。对开合屋盖最不利状态在Hollywood Storage地震波作用下采用增量动力分析研究其抗连续倒塌性能,给出随加速度增大而进入屈服状态的杆件及承受的最大加速度幅值。
For a large span openable truss roof,there are six basic structural states according to different opening methods,and the structure may encounter earthquakes in any state.The earthquake-resistance of the structure in various basic states and the continuous collapse resistance under earthquake action are analyzed.The response spectrum method is used to calculate the response of structures in different states under the action of earthquakes to determine the most unfavorable state of openable roofs.Incremental dynamic analysis method is used to study the progressive collapse resistance under the action of Hollywood Storage seismic waves,the members that enter the yielding state with the increase of acceleration and the maximum acceleration amplitude withstand are given.
