  • 章节内容简介 [ Chapter Content Abstract ]

梁柱纤维截面模型的具体思路是将单元内部积分点处的截面离散为若干纤维,并假定截面满足平截面假定,由截面的曲率和中性轴的位置获得纤维应变,由纤维应变结合所采用的材料滞回本构关系获得纤维的应力,将纤维的应力沿截面积分可以获得截面的轴力和弯矩。纤维截面的压弯刚度矩阵如下:

式中 为截面划分的纤维数量, 、 为第i条纤维的几何中心坐标, 为第i条纤维的材料刚度。

纤维截面模型通过材料积分获得截面的内力-变形关系,与塑性铰模型直接给出截面内力-变形关系相比,在描述截面压弯耦合非线性行为方面有着更大的优势。本章将对PERFORM-3D[1,2]中的梁、柱纤维截面模型进行介绍。
