| 摘 要： | 在前期试验和理论研究的基础上,将密肋壁板结构中的密肋复合墙板等效为整体斜撑,提出结构的刚架-等效斜撑模型,并结合试验数据确立了该模型的主要参数及塑性铰的设定。采用该模型建模对前期振动台模型试验进行了模拟,结果表明,二者在各层加速度时程反应值、反应波形以及监测点的最大侧向位移方面吻合较好,说明刚架-等效斜撑模型能较好地模拟结构的动力特性及弹塑性变形情况,可用于密肋壁板结构的弹塑性时程反应分析及非线性变形验算。

| Abstract: | According to the previous researches and experiments,the rigid frameequivalent brace model of multi-ribbed slab structure is put forward,in which the multi-ribbed composite wall is equivalent to a whole diagonal brace.Based on the previous tests,the main parameters and the plastic hinge settings of the model are established.By using this model,a shaking table test of a multi-ribbed slab structure model is simulated.And the calculation results tally well with the experimental results in acceleration time his... |
