为研究细密柱框架结构体系的抗震性能,对一个两层密细柱框架结构的足尺模型进行了拟静力往复荷载实验,给出了实验结果;利用有限元计算软件ABAQUS、SAP2000和PKPM对模型进行了推覆分析,并与实验结果进行了对比,发现软件分析所得的裂缝模式和塑性铰位置均与实验结果吻合;最后得出了该实验模型的性能曲线,并对其在罕遇地震作用下的性能进行了评价.实验结果表明,作为框架结构的一种,密细柱框架体系可以发挥良好的抗震性能.
In order to study the seismic behavior of the frame structure of a fine column, a full-scale reciprocal loading test of a two-layer dense column frame structure is carried out and the experimental results are given. Using the finite element calculation software ABAQUS, SAP2000 and PKPM The model is compared with the experimental results. The results show that the fracture modes and plastic hinge positions obtained by the software are in good agreement with the experimental results. Finally, the performance curves of the experimental model are obtained and analyzed in rare earthquakes Under the action of the performance evaluation.The experimental results show that, as a kind of frame structure, dense column frame system can play a good seismic performance.
