摘　　要：针对井字梁、十字梁和单向次梁三类梁板式楼盖,根据荷载效应等效原则,利用APDL程序在ANSYS有限元软件中生成参数化消防车等效均布活荷载计算模型,分别计算了不同覆土厚度和柱跨下,三类楼盖主、次梁和楼板的消防车等效均布活荷载。研究三类楼盖各类构件消防车等效均布活荷载的区别及其影响因素,给出了主、次梁相对楼板的等效均布活荷载折减系数。The fire engine equivalent uniform live load for main and secondary beams and slabs of well-shaped beam floor,cross beam floor and one-way beam floor with different soil thicknesses and floor spans were calculated respectively from a parametric finite element model based on APDL program in finite element software ANSYS using the equivalent component effect method. The differences and influencing factors of fire engine equivalent uniform live load for components in three kinds of floors were studied. The equivalent uniform live load reduction coefficients of the main and secondary beams relative to the floor were given.
