摘要: 提出了利用承載力曲線的響應(yīng)點(diǎn)判定抗震性能的簡易方法. 該方法無需進(jìn)行地震時(shí)程反應(yīng)分析,只利用傳統(tǒng)的靜力計(jì)算結(jié)果,判定抗震性能. 同時(shí)還驗(yàn)證了 JSCA 抗震性能篇“簡易法”判定標(biāo)準(zhǔn)的合理性.

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; 極限承載力計(jì)算; 需求譜; 能力譜

Abstract:Simplified procedure of seismic performance evaluation is proposed using spectral responses by capacity spectrummethod. It need not perform iterative calculations and makes use of results of static analyses obtained in conventional designprocedure. Also, the validity of the criteria proposed in JSCA Seismic Performance Design Guideline “simplified method”is verified by capacity spectrum method.

Keywords:performance-based design; static design; low or middle-rise building; seismic performance level; story drift;ultimate bearing capacity calculation, demand spectrum; capacity spectrum
