框架-核心筒结构振动台试验全过程动力弹塑性仿真

Full range dynamic elasto-plastic numerical simulation of the shaking table test of the frame-core wall structure

采用动力弹塑性分析方法,对某高层建筑普通钢筋混凝土框架-核心筒结构的振动台试验的全过程进行仿真分析,并就结构动力特性、顶点位移、最大层间位移角以及结构损伤与破坏过程同振动台试验结果进行了对比分析。结果表明,仿真分析结果与试验结果吻合良好;所采用的动力弹塑性分析方法能够正确反映结构的受力状态与变化过程,实现了振动台试验全过程的模拟与结构破坏过程的重现。

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.
