【摘要】 在指出现有多弹簧模型存在问题的前提下,结合现有分析剪力墙的多垂直杆单元模型,提出了一种拓展的多垂直杆单元模型,这种模型可适用于各种截面形式的柱、墙肢和梁。另外,本文也提出了考虑刚度下降段的简化方法,最后提供了一个算例,算例结果表明本文模型的合理性。更多还原

【Abstract】 On the premise of pointing out the problems of existing multi-spring model,combining with multi-vertical-line-element model for analyzing shear wall,a kind of multi-vertical-line-element model is brought forward,which is suitable for columns,wall limbs and beams with all kinds of section form.The simplified method considering stiffness subsidence is put forward in the paper.The included example shows the reasonability of the model.更多还原
