［摘要］无梁楼盖因受力直接，能充分发挥厚板的承载能力，而且施工方便，在工程中应用越来越多。对带托板无梁楼盖结构设计经常遇到的几个问题进行了分析，比如托板尺寸对楼板弯矩的影响，桩的作用对无梁底板的影响，用钢量的影响因素，采用有限元计算时板带弯矩如何取值，以及托板的最小配筋率等，得到了无梁楼盖的经济选型并给出了设计建议。

Abstract:Because flat slab can transfer force directly, it can give full play to the carrying capacity of the thick plate, and the construction is convenient. Therefore, flat slab is applied more and more in engineering. Several problems often encountered in the structural design of flat slab with pallet were analyzed, such as the effect of the pallet size on the floor bending moment, the effect of the pile on the bottom slab, the influence factor of steel quantity, how to determine the value of the bending moment of the plate belt in finite element calculation, and the minimum reinforcement ratio of the pallet. The most economic selection of the flat slab was obtained and the design suggestions were given.

Keywords:flat slab; pallet;  minimum reinforcement ratio
