摘要 利用ADINA有限元软件对4个无粘结预应力装配混凝土节点进行了非线性有限元分析,并且对分析结果与试验结果进行了对比。结果显示:所采用的分析模型在梁柱缝隙处的开合、应力分布、试件变形和恢复力骨架关系上与试验吻合较好,说明所采用的分析单元和模型有利于详细了解无粘结预应力装配梁的非线性性能和抗震性能。 This paper analyses nonlinear behaviors and seismic performances of 4 unbonded post-tensioned precast concrete beams with ADINA finite element software. The gap opening/closing, stress distribution, specimen deformation, the hysteresis framework relationship are in good agreement with those of the tests. It is shown that the model is very effective for gaining detailed knowledge of the nonlinear behavior and seismic performance of unbonded post-tensioned precast concrete beams.
