[提要] 分析了底層大開間框剪、上部小開間組合墻房屋的受力特點(diǎn)，采用串并聯(lián)多質(zhì)點(diǎn)彈塑性動力計(jì)算程序，分析了房屋的抗震性能及座落在縱向托梁上的橫墻的動力響應(yīng)，得出的結(jié)論是這類房屋的抗震性能與底層框剪組合墻房屋相似，可作為底層框剪組合墻房屋來處理。
[關(guān)鍵詞] 組合墻房屋 底層大開間 抗震性能The bearing characteristics of the composite masonry building supported on frame-shear structure with large spacing at first storey are analyzed. The elasto-plastic time history analysis is conducted by using of the series-parallel multiple mass system. The results show that the earthquake resistant behavior of this kind of building is as good as the similar building but with small spacing of the frame-shear structure at first storey, and can be dealt with the same design code.
Keywords: composite masonry building; large spacing; earthquake resistant behavior
