四川省展览馆抗震加固施工技术

Construction Technology of Seismic Strengthening for Sichuan Exhibition Hall

四川省展览馆使用至今已有30多年,已完全不能满足社会需求,需要对展览馆进行加固改造。改造前,首先对展览馆结构进行了性能检测,根据检测结果制定了加固方案。结构上通过采用增加水平支撑,混凝土柱外包型钢,梁粘贴碳纤维布和粘钢等措施,提高了结构的抗震能力,加强了结构的整体性。该建筑已投入使用一年多,抵抗住了5.12汶川地震的考验。

Sichuan Exhibition Hall has been working for over thirty years, cann＇t satisfy the present social requirements, and must be strengthened and rebuilt. Structure performances of the exhibition hall are inspected before reconstruction. Based on inspection results, strengthening scheme is put forward that is adding horizontal support on structure, strengthening concrete column with epiboly profiled steel method, strengthening beams with carbon fiber reinforced polymer or steel plate. The strengthening scheme improves seismic ability and integrity of building. The strengthened Sichuan Exhibition Hall has been working for over one year, and experiences Wenchuan Earthquake successfully.
