线荷载作用下的单向板内力分析

摘要

This paper analyzed calculation of main direction moment of one-way slab as single span( slab),while ignoring the moment in this direction,leading to the cracks situation of slab in secondary direction under linear loads action in actual engineering calculation,using Navier solution calculation and using MATLAB drew the one-way slab under linear loads action,and taking the length to width ratio as the basic parame-ters,discussed the changes situation of primary and secondary direction moment,gained some conclusions.%对实际工程计算时通常将线荷载作用下的单向板按单跨（板）梁来计算主方向上的弯矩，而忽视了次方向上的弯矩，导致板底出现次方向上裂缝的情况作了分析，采用纳维叶解法计算并运用MATLAB绘制了受线荷载作用的单向板，并以长宽比为基本参数，讨论了主次方向上弯矩的变化情况，得出了一些结论。
