摘要
论述了新修编的国家建筑标准设计图集05G515轻型屋面梯形钢屋架在设计计算中未考虑在吊车荷载和永久荷载组合下弦杆的受力,分析了在不同吊车荷载作用下屋架下弦杆的内力,得出屋架下弦杆出现压力时的吊车起重量,供设计人员参考。
It tells that the internal force of bottom chord bar under the group action of crane load and permanent load is not considered in the design and calculation in the latest edition of state building standard-05G515, The impact of different crane loads on the bottom chord bar of steel roof truss is analysed, and the crane loads when the bottom chord bar is undex pressure is presented, which have some references to the designers.
