摘要
本文以矩形薄板变曲单元为基础,根据坐标变换原理,推导出斜交薄板弯曲单元刚度矩阵,并且处理了内力影响面的计算及横向装配式铰结斜板桥的计算单元.编制了计算程序,通过实例计算证明,这种单元精度可靠,特别适用于斜板桥的计算.
Besed on the rectanguhar thin plate bending theory,the stiffness matrices of the skewed-plate bending element are formulated by the coordinate transfer in this paper,and some computation problems of the internal force′s influence surface and of the skewed-plate bridge with hinged joint by assembling transversly are solved. Through programming and computing, it it proved that the skewed-plate bending element is accurate, reliable and suitable to the computation of the skewed-plate bridge especially.
