摘要
本文主要介绍了上海某医院多层裙房的抗震设计与分析。裙房地上共4层,采用了钢筋混凝土框架结构,结构存在扭转不规则、平面凹凸不规则、楼板局部不连续、竖向抗侧力构件不连续等不规则项。采用ETABS和盈建科两种结构设计软件进行对比计算,结构各项指标满足规范限值要求,同时对结构进行多遇地震作用下的弹性时程补充分析、楼板应力分析以及罕遇地震作用下静力弹塑性分析等。结果表明各项指标均达到了设计的要求,确保了结构的安全性。
This paper mainly introduces the seismic design and analysis of a multi-storey podium building in a hospital in Shanghai.There are four floors on the ground of the podium,and the reinforced concrete frame structure is adopted.The structure has irregular torsion,irregular concave and convex plane,local discontinuity of the floor,discontinuity of vertical lateral force members and other irregular items.ETABS and Yingjianke structural design software were used for comparative calculation,and the indicators of the structure met the limit requirements of the code.At the same time,supplementary analysis of elastic time history under the action of frequent earthquakes,floor stress analysis and static elasto-plastic analysis under the action of rare earthquakes were carried out.The result shows that all the indicators meet the design requirements and ensure the safety of the structure.
