本文作者根据四根体外预应力简支梁的试验 ,得出了体外预应力梁在非线性状态下的反应 ,并利用大变形条件下的杆件结构变形推导了包括几何非线性和材料非线性的单元刚度矩阵 ,同时编制了非线性有限元程序进行验证。
Based on the tests of four externally prestressed simply supported beams, the authors obtained the response of the externally prestressed beams under nonlinear conditions and deduced the geometrical nonlinearity and the material nonlinearity using the structural deformation under the condition of large deformation Stiffness matrix, at the same time prepared a nonlinear finite element program to verify.
