摘要
某音乐厅主楼框架存在偏心布置、楼板局部不连续、斜柱等不规则情况;音乐厅功能区为带钢桁架屋面的单跨框架;大跨钢结构屋盖表皮依附在主楼上,结构设计较为复杂。针对主楼结构进行了小震弹性时程分析及大震静力弹塑性分析,结果表明结构具有较好的抗震性能,结构各项指标均符合国家相关规范要求。针对楼板应力、斜柱承载力、功能区屋面桁架及大跨度钢屋盖的设计进行了分析研究,结果表明楼板、斜柱、屋面钢桁架和大跨钢屋盖设计安全可靠,满足抗震性能化设计要求。
A concert hall is studied subject to a structure with unfavorable irregularities including eccentric layout,partially discontinuous floor and inclined columns. The function area of the concert hall is a single-span frame with steel truss roof. Besides, a large span steel roof is attached to the main structure. Elastic time-history analysis and static elastic-plastic analysis were performed for the main structure. The results show that the structure has good seismic performance and all the structural indexes meet the requirements of relevant Chinese codes. The floor stress, inclined capacity of inclined column, design of roof truss in functional area and large span steel roof are analyzed, indicating the safe design and reliable to meet seismic performance design requirements.
