本文介绍在材料应力应变关系为线性的情况下,对于具有大变形的平面框架如何建立共梁单元切线刚度矩阵的方法。这种切线刚度矩阵可用来研究大变形框架的力与位移关系。
This article describes how to establish the tangent stiffness matrix of a common beam element for a plane frame with large deformation when the material stress-strain relationship is linear. This tangential stiffness matrix can be used to study the relationship between force and displacement of large deformation frames.
