摘要: 使用多質(zhì)點(diǎn)模型對(duì)中低層鋼筋混凝土建筑和鋼結(jié)構(gòu)建筑進(jìn)行了地震時(shí)程反應(yīng)分析. 結(jié)果表明,由響應(yīng)值確定的地震等級(jí)與由“簡(jiǎn)易法”評(píng)價(jià)的地震等級(jí)相當(dāng).

關(guān)鍵詞: 性能設(shè)計(jì); 靜力設(shè)計(jì); 中低層建筑; 抗震性能等級(jí); 層間位移角; 時(shí)程反應(yīng)分析; 多質(zhì)點(diǎn)模型

Abstract:Time history response analysis was conducted using a multi mass model assuming low-rise RC an S buildings,and it was shown that the seismic grade determined from the response values was equivalent to the seismic grade determinedby the " simplified method" .

Keywords:performance-based design; static design; low or middle-rise building; seismic performance level; story drift;time history analysis; multi-degree-of-freedom system
