[摘要] 對(duì)某密肋樓蓋房屋的主體結(jié)構(gòu)進(jìn)行全面的抗震鑒定，該房屋受當(dāng)時(shí)經(jīng)濟(jì)及技術(shù)等方面因素的制約，在設(shè)計(jì)荷載及材料強(qiáng)度取值、結(jié)構(gòu)安全儲(chǔ)備大小等方面均較現(xiàn)行國(guó)家設(shè)計(jì)規(guī)范和標(biāo)準(zhǔn)要求有一定的差距。為保證房屋用途變更后繼續(xù)安全使用，進(jìn)行了原始資料調(diào)查、現(xiàn)場(chǎng)檢測(cè)及結(jié)構(gòu)抗震性能評(píng)定，根據(jù)評(píng)定結(jié)果提出了相應(yīng)的加固方案。加固后的結(jié)構(gòu)基本達(dá)到重點(diǎn)設(shè)防類抗震設(shè)防標(biāo)準(zhǔn)，結(jié)構(gòu)整體性及承載力得到顯著提高，改善了結(jié)構(gòu)的安全狀況。

Abstract: A comprehensive seisnuc evaluation fora multi-ribbed floor building was made. The building, completed in 1982, was designed with low economic and technical, including design load and material strength value, structure security reserve size etc, which cannot meet the demand of the current code. To insure the safety of the building which utility is changed, initial data were investigated, on-site test was performed,and then seismic performance evaluation was made. According to the evaluation, the paper puts forward corresponding reinforcement measures, and the structure achieves the seismic fortification criteria. This not only significantly enhances the structural integrity and load-carrying capacity, but also improves the safety situation of the structure.
Keywords: frame aseismic walls; field detection; seismic evaluation; strengthening method
