[摘要]  消防車荷載對(duì)結(jié)構(gòu)設(shè)計(jì)的影響較大，現(xiàn)行《建筑結(jié)構(gòu)荷載規(guī)范》(GB 50009—2012)采用彈性理論計(jì)算雙向板的消防車等效均布活荷載，而工程設(shè)計(jì)中一般習(xí)慣采用塑性鉸線法進(jìn)行雙向板的設(shè)計(jì)，這兩者可能不太匹配。本文提出用塑性理論計(jì)算雙向板的消防車等效均布活荷載，通過計(jì)算得到了常用跨度、覆土厚度下的消防車等效均布活荷載，可供工程設(shè)計(jì)參考。

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
