【摘要】 预应力结构由于其具有提高构件的抗裂度,改善结构的受力性能,提高构件的刚度,减小构件变形等特点得到了建筑工程广泛的应用。本文运用有限元分析软件ANSYS,对框架边柱节点进行模拟计算,通过对比在不同轴压比下节点的位移延性系数,得出随着轴压比的增大,节点的延性不断减小。更多还原

【Abstract】 Prestressed structure is widely used in the construction engineering now,because it can improve crack resistance of the component,improve mechanical properties of the structure,raise the stiffness of components,reduce the component deformation characteristics.This paper uses finite element analysis software ANSYS to simulate the frame side column node,through the contrast without the displacement ductility coefficient of node under axial pressure ratio,concludes that with the increase of axial compression ratio,the ductility of the node being reduced.更多还原
