长泾人民大会堂建于1969年,需要保留并进行改造和功能升级,改造后的建筑外观要求达到“修旧如旧”的目的,实现难度较大。结构类型属单层空旷房屋,结构设计优先采用增强结构整体抗震性能的方案,针对工程特点选择加固方法,并广泛应用钢结构系统进行体外加固,达到了预期的要求。 The Great Hall of the People in Changjing was built in 1969 and needs to be preserved and rebuilt and function upgraded. The appearance of the rebuilt building is required to achieve the goal of “repairing the old as the old” and achieving greater difficulty. The structure type belongs to the single-storey open-space house. The structural design gives priority to the scheme of enhancing the overall seismic performance of the structure, selects the reinforcement method according to the engineering characteristics, and widely applies the steel structure system for reinforcement in vitro, which meets the expected requirements.
