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.According to the constitution of the composite open-web steel- concrete floor, the method of continuous analysis of the structure was given. The nonclassical plate theory of the three generalized displace-ments was adopted to the calculation of the flexural rigidity of the top and bottom surface layer, and to the alte-ring 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 sheafing force of the composite open-web floor under uniform load were achieved.
