［摘要］某教學(xué)樓建于1991年，地下1層，地上9層（局部為11層），大屋面建筑高度為34m，由于原設(shè)計(jì)按78規(guī)范設(shè)計(jì)，在建筑功能方面不能滿足目前的需要和安全使用要求，需要進(jìn)行加固改造。根據(jù)建筑物的實(shí)際情況和結(jié)構(gòu)特點(diǎn)，通過(guò)運(yùn)用結(jié)構(gòu)綜合抗震能力分析方法和多種加固手段，在保持原有建筑風(fēng)貌的前提下，實(shí)現(xiàn)了提高建筑抗震能力和改善建筑使用功能的協(xié)調(diào)，取得了一些學(xué)校類建筑加固改造中實(shí)施的經(jīng)驗(yàn)，可供類似工程加固改造參考。［關(guān)鍵詞］教學(xué)樓; 板柱-抗震墻結(jié)構(gòu); 消能器; 加固中圖分類號(hào)：TU352 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2016)05-0044-04
Performance-based design and analysis on strengthening of plate-column-shear wall structure of a teaching buildingNie Qi1,2, Tang Caoming1,2, Yang Tao1,2, Guo Hao1, Huang Ruhui1, Xiao Qing1（1 China Academy of Building Research, Beijing 100013, China; 2 Disaster Prevention Research Center of Housing and Urban and Rural Construction, Beijing 100013, China）Abstract:A 9-story (locally 11-story) teaching building with one-layer basement was built in 1991, with architectural height of 34m at its highest level in roof. The original design accords to the standard in 1978 and building functions and seismic safety can not fulfill the current requirements, so seismic strengthening and transformation are needed. According to the actual conditions and structural characteristics of the building, the compound structural seismic capability analysis methods were used as well as a variety of strengthening means. Under the premise of keeping the original architectural style, the coordination was achieved to improve the building's seismic capacity and improve the building's service function. Some implemented experience in school building strengthening and transformation were obtained, providing reference for strengthening and transformation in similar engineering.Keywords:teaching building; plate-columnshear wall structure; energy dissipation damper; strengthening
