人防荷载作用下地下车库楼盖结构选型

Selection of floor structure of underground garage under load of civil air defense

按照GB 50038—2005《人民防空地下室设计规范》[1]的计算和构造规定,建立了人防荷载作用下五种地下车库楼盖结构计算模型,统计了钢筋、混凝土、模板用量,并分析了各类楼盖材料用量差异的原因。根据材料用量统计结果,通过计算和比较楼盖的单方造价,为人防荷载作用下地下车库楼盖结构选型提供了参考和建议。

Based on calculation and construction regulations of GB 50038--2005＂ Code for design of civil air defense basement＂, the calculation models of five underground garage floor structure are established, the quantity of steel, concrete and building template is counted up, and the difference of various material requirement is analyzed. Based on statistical results of the material requirement, by calculating and comparing the per square meter cost of floor, the reference and suggestions for selecting the floor structure of underground garage under load of civil defense are provided.
