[摘要]  消防车荷载对结构设计的影响较大，现行《建筑结构荷载规范》(GB 50009—2012)采用弹性理论计算双向板的消防车等效均布活荷载，而工程设计中一般习惯采用塑性铰线法进行双向板的设计，这两者可能不太匹配。本文提出用塑性理论计算双向板的消防车等效均布活荷载，通过计算得到了常用跨度、覆土厚度下的消防车等效均布活荷载，可供工程设计参考。

Abstract: The fire engine load has a great effect on structure design. Load code for the design of building structures(GB 50009—2012) calculates equivalent uniform live load for fire engines on two-way slab with theory of elastic, this practice may have a conflict with the plasticity design method for two-way slab. This paper suggests a method of calculation value of equivalent uniform live load for fire engines on two-way slab with theory of plasticity and provides the calculation results for common span and common soil thickness.   

Keywords: fire engine; equivalent uniform live load; theory of plasticity; soil thickness
