（天津大学建筑设计研究院，天津300073）[摘要] 最新实行的《建筑结构荷载规范》(GB50009-2012)针对消防车等效活荷载荷载取值问题进行了细化，规定双向板跨度越小取值越大。对于楼板这种规定符合实际情况也更为合理，但是对于主梁也这样取值不慎合理。本文对GB50009-2012规范中对主梁的消防车荷载取值的问题进行了分析，并且提出了相应的设计建议。[关键词] 消防车;等效活荷载; 主梁;取值建议中图分类号：TU312.1 文献标识码：A 文章编号：1002-848X(2013)S1-0718-03Research on reasonable value of equivalent live load for fire engine on the main beamZhang Jinhai, Ding Yongjun, Wang Xiang’an, Jia Li, Wang Heng(Tianjin University Research Institute of Architectural Design & Urban Planning,Abstract: There are refinement rules of assigning live load for fire engine under different span of two-way slab appeared in the latest Load code for the design of buildings (GB 50009-2012), which leads to the result that the greater the plate across is, the small values it was assigned. As for the case of floor slab, it meets the real situation and sounds reasonable. But as for the case of main beam, those standards seem not reasonable. In this thesis, the problem of assigning live load for fire engine main beam accord to standard GB 50009-2012 have been analyzed and some design recommendations have been proposed.Keywords: fire engine; equivalent live load; main beam; value suggestions作者简介：张金海，工学硕士，高级工程师，Email:zjh340@sina.com。
