［摘要］采用動(dòng)力彈塑性分析方法，對(duì)某高層建筑普通鋼筋混凝土框架-核心筒結(jié)構(gòu)的振動(dòng)臺(tái)試驗(yàn)的全過程進(jìn)行仿真分析，并就結(jié)構(gòu)動(dòng)力特性、頂點(diǎn)位移、最大層間位移角以及結(jié)構(gòu)損傷與破壞過程同振動(dòng)臺(tái)試驗(yàn)結(jié)果進(jìn)行了對(duì)比分析。結(jié)果表明，仿真分析結(jié)果與試驗(yàn)結(jié)果吻合良好；所采用的動(dòng)力彈塑性分析方法能夠正確反映結(jié)構(gòu)的受力狀態(tài)與變化過程，實(shí)現(xiàn)了振動(dòng)臺(tái)試驗(yàn)全過程的模擬與結(jié)構(gòu)破壞過程的重現(xiàn)。［關(guān)鍵詞］高層建筑; 鋼筋混凝土框架-核心筒; 振動(dòng)臺(tái)試驗(yàn); 動(dòng)力彈塑性仿真中圖分類號(hào)：TU973.2 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2015)23-0001-08
Full range dynamic elasto-plastic numerical simulation of the shaking table test of the frame－core wall structureXu Ziguo, Xu Peifu, Xiao Congzhen(China Academy of Building Research, Beijing 100013, China)Abstract: Using dynamic elasto-plastic analysis method, the full range of the shaking table test of a high-rise building with reinforced concrete frame-core wall structure was numerical simulated, and the simulation results were compared with the shaking table test results, including the structural dynamic characteristics,top displacement, maximum story drift ratio, structural damage and destruction process. The results show that simulation results are in good agreement with the test results. Adopted dynamic elasto-plastic analysis method can correctly reflect the stress state and change process of the structure, which achieves a simulation of the full range shaking table test and reproduces the structural failure process.Keywords: high-rise building; reinforced concrete frame-core wall; shaking table test; dynamic elasto-plastic numerical simulation
