【摘要】 根据钢-混凝土组合空腹板架的构造特点,提出了此结构的连续化分析方法.采用具有三个广义位移的非经典平板理论,并考虑上下表层抗弯刚度,将组合空腹板架结构连续化为具有三层构造的夹层板.得到了拟夹层板的连续化分析的相关微分方程,并推导了矩形平面周边简支条件下高阶微分组的解,得到组合空腹板架结构在均布面荷载作用下的位移、应变、弯矩、剪力的表达式.更多还原

【Abstract】 According to the constitution of the composite openweb steel-concrete floor,the method of continuous analysis of the structure was given.The nonclassical plate theory of the three generalized displacements was adopted to the calculation of the flexural rigidity of the top and bottom surface layer,and to the altering of the composite open-web floor into a sandwich plate of three-layer structure,thus related differential equation of the continuous analysis of pseudo-sandwich plate was got,and the solution of higher order differential equation was deduced for the rectangular four-side supported composite open-web steel-concrete floor.Also the expressions of displacement,strain,flexural moment and shearing force of the composite open-web floor under uniform load were achieved.更多还原
