基于参变量变分原理的修正多垂直杆墙元模型
|
摘要
根据剪力墙的受力和变形特点,对多垂直杆墙元模型进行修正,求解过程采用参变量变分原理。利用此方法对"一"、"十"字型短肢剪力墙元进行非线性分析。该法摒弃了平截面假定的限制,考虑了剪滞效应和翼缘的影响。
The modified multi-vertical-line-element(MVLE) model is solved by means of the parametric variational principle,and nonlinear analysis of short leg wall is performed in detail.The effect of shear lag and shear deformation is considered in this model,which is free of the restriction of plane assumption.Thus,it provides a good method for the shear wall.Finally,a simple example is given.
