［摘要］唐山市青少年宮東區(qū)是一個(gè)混凝土與鋼架聯(lián)合的復(fù)雜建筑，混凝土主體結(jié)構(gòu)南側(cè)與帶斜梁落地的鋼架相連。采用MIDAS反應(yīng)譜法和彈性時(shí)程對(duì)整體模型地震作用下的響應(yīng)進(jìn)行了分析，并與單獨(dú)混凝土SATWE計(jì)算結(jié)果和單獨(dú)鋼結(jié)構(gòu)MIDAS計(jì)算結(jié)果進(jìn)行了量化比較，結(jié)果表明鋼結(jié)構(gòu)對(duì)混凝土結(jié)構(gòu)的影響較小，主體結(jié)構(gòu)可以單獨(dú)設(shè)計(jì)，而混凝土結(jié)構(gòu)對(duì)鋼結(jié)構(gòu)的影響較大，若鋼結(jié)構(gòu)單獨(dú)設(shè)計(jì)，偏于不安全。采用彈塑性靜力分析法分析了混凝土結(jié)構(gòu)在罕遇地震作用下的變形能力，結(jié)果滿足規(guī)范要求。采用彈塑性時(shí)程法分析了罕遇地震作用下鋼架的變形和塑性鉸分布狀態(tài)，結(jié)果表明在大震作用下鋼架仍有強(qiáng)度和變形儲(chǔ)備能力；同時(shí)還對(duì)鋼架進(jìn)行了整體穩(wěn)定分析，結(jié)果表明鋼架以整體穩(wěn)定性為安全控制因素，且體系穩(wěn)定設(shè)計(jì)滿足強(qiáng)屈比與延性性能目標(biāo)。

Abstract:The eastern of Tangshan  Children′s Palace is a complicated building, mixed with concrete and steel frame.Its south part of the concrete structure is connected with the fall sloping steel frame. The earthquake response spectrum and elastic-plasticity analysis are carried on in the structure with MIDAS software, and a quantization comparison is made with SATWE. The result shows that the concrete part has serious influence on the steel frame.If the steel structure is designed separately,the result will be unsafe. The deformation capacity and the plastic hinge distribution of steel frame under the condition of rarely earthquake sufficient are carried with Pushover static elastic-plasticity analysis, and its result shows that the steel frame has sufficient capability of strength and deformation.
A stability analysis is carried on the steel frame, and the overall stability is the control factor of steel frame. The system stability design could meet the requirement of the ductility and the ratio between strength and yield strength.
Keywords:composite structure; interactive action; elasticity; static elastic-plasticity; time history; analysis; overall stability
