摘要: 定量評價結(jié)構(gòu)的防地震倒塌性能對于降低地震下人員傷亡和經(jīng)濟(jì)損失具有非常重大的意義. 國際上,美國等已將結(jié)構(gòu)防地震倒塌性能定量評價納入到相應(yīng)的設(shè)計指南中. 為此,中勘協(xié)《建筑結(jié)構(gòu)抗震性能化設(shè)計標(biāo)準(zhǔn)》亦將引入防地震倒塌設(shè)計,這對提升我國工程建設(shè)的地震安全性能具有非常重要的意義. 首先從分析方法、倒塌判別準(zhǔn)則、倒塌風(fēng)險評價方法三方面簡要介紹了《建筑結(jié)構(gòu)抗震性能化設(shè)計標(biāo)準(zhǔn)》中防地震倒塌性能設(shè)計的相關(guān)規(guī)定. 進(jìn)而通過兩個典型案例,即中美規(guī)范設(shè)計結(jié)果對比、單重和雙重結(jié)構(gòu)體系對比,詳細(xì)介紹了防倒塌性能設(shè)計方法在工程建設(shè)中的實(shí)際應(yīng)用.

Abstract: Quantitative evaluation of the structure capacity against earthquake-induced collapses is of great significance toreduce human casualties and economic losses under earthquakes. Internationally, the United States and other countries haveincorporated the quantitative evaluation of the structure capacity against earthquake-induced collapses into correspondingdesign guidelines. Now, similar contents will be included in the Standard for performance-based seismic design of buildingstructures of China Engineering & Consulting Association, which is of great importance to improve the seismic safety ofengineering constructions in China. The provisions of performance-based design for earthquake-induced collapse in thestandard from three aspects were briefly introduced: analysis method, collapse discrimination criteria and collapse riskevaluation method. Then, based on two typical cases ( i. e. , comparison of design outcomes of Chinese and Americancodes, comparison of the single and dual lateral force resisting systems), the practical applications of the performance-based design method for earthquake-induced collapse in engineering constructions were introduced in detail.
Keywords:performance-based seismic design; collapse; Chinese and American codes; lateral force resisting system;structure capacity against earthquake-induced collapses
