考虑相对滑移钢-混凝土结合梁内力分析

钢-混凝土结合梁在荷载作用下,混凝土板和钢梁之间将产生相对滑移,导致结构内力的重分配,需考虑相对滑移的影响.采用伽辽金法计算结合梁考虑相对滑移的静力响应,采用正交函数作为位移函数,通过推导出形常数与载常数的计算公式,最后用渐近法计算分析并比较连续结合梁的内力.结果表明:计算简单精度较高.

Consider the Relative Slip of Steel-concrete Composite Beam Analysis of Internal Forces

Steel-concrete composite beam at load,between the concrete slab and steel beam will have a relative slip,resulting in the structure of the re-distribution of internal forces,need to consider the impact of relative slip.Galerkin's method to calculate the relative sliding girder consider the static response,the use of orthogonal functions as displacement functions,through constant and derived the formula for calculating the constant setand,finally with the asymptotic analysis method to calculate and compare t...
