原世博临时建筑改造为永久性结构的加固工艺研究

Reinforcement Process Study on Reconstruction of Temporary Building of Original World Expo into Permanent Structure

原世博上汽通用馆需改造为永久性的儿童艺术剧场。为此,围绕结构加固难题,系统地开展了地基加固是否影响紧邻地铁的施工研究、临时结构向永久结构转换施工研究等。通过引入屈曲支撑,屋架适当加固,满足了永久抗震等级要求,该工艺研究为同类工程提供了借鉴和参考。

The original World Expo SAIC GM Pavilion needs to be reconstructed into a permanent children's art theater.To this end,focusing on the difficult problem of structural reinforcement,whether the foundation reinforcement affects the adjacent subway construction,and the reconstruction of temporary structure into permanent structure are systematically studied.By applying buckling support,the roof truss is properly reinforced to meet the requirements of permanent antiseismic grade.The research of this process provides a reference for similar projects.
