摘要
本文依据梁单元位移算子法求变形的理论,建立两个不同截面尺寸连接的梁单元位移关系,导出求变截面梁的节点位移的通用方程,为工程技术提供一种简单、实用.又有可靠精度的变形计算方法。
Based on the theory of beam deflection analysis by the beam unit displacement operator method. the displacement relation for two connected beam units with different cross sections is established.and the general equation for calculating the displacement of the node on non uniform cross section beams is derived.The method is simple, practical and reliable for deflection calculations.
