高强钢筋在双层地库结构中设计应用对比分析

Comparative Analysis of the Design and Application of High-strength Steel Bars in Double-layer Basement Structure

针对双层地库结构,采用3种高强钢筋,分别是HRB400、HRB500、T63/E/G,在不同覆土厚度为1.0、1.2、1.5m的情况下,应用于大、中、小3种柱网间距,在满足国家结构设计标准的前提下,分析高强钢筋在地库结构中的梁板含钢量。综合考虑施工、设计、采购造价等方面因素,分析了高强钢筋的优化适用范围,为以后高强钢筋在地库中的应用提供了指导建议。

For the double-layer basement structure,three types of high-strength steel bars,namely HRB400,HRB500,and T63/E/G,are used in different column grid spacing of large,medium,and small with different cover soil thicknesses of 1.0,1.2,and 1.5 m.On the premise of meeting the national structural design standards,the steel content of beams and slabs in the basement structure with high-strength steel bars is analyzed.Considering the factors such as construction,design,and procurement costs,the optimized application scope of high-strength steel bars is analyzed,which provides guidance and suggestions for the future application of high-strength steel bars in basement.
