摘　　要：结合计算实例,对梁板式楼盖在几种主流计算模式下的经济性展开分析讨论,并得出在消防车荷载下,顶板采用塑性算法的板配筋优势较大;板厚较厚(≥300mm)、消防车占比较小时,梁板协同算法较传统算法优势较为明显;单向单次梁方案在消防车荷载占比较小时,指标有一定优势等结论。Combined with the calculation examples, this paper analyzes and discusses the economy of beam slab floor under several mainstream calculation modes, and draws the following conclusions, as under the load of fire truck, the plate reinforcement with plastic algorithm is more advantageous;when the plate thickness is thicker(≥300mm) and the proportion of fire engines is small, the beam-board collaborative algorithm has obvious advantages over the traditional algorithm;When the load ratio of the fire truck is small, the index of one-way single beam scheme has certain advantages, etc.
