一、前言“钢筋混凝土及予应力混凝土屋架考虑非弹性变形对屋架承载能力影响”的研究课题,是目前我国土建设计中急待解决的一个问题,也是钢筋混凝土结构设计规范(TJ10—74)遗留下来的研究课题之一。我们屋架科研小组在查阅了一些国内外的文献,搜集和学习了国内所做过的一部分钢筋混凝土屋架试验研究资料和论文的基础上,从1976年开始着手做了一些钢筋混凝土屋架
1. Foreword “The research topic of reinforced concrete and prestressed concrete truss considering the influence of non-elastic deformation on the truss bearing capacity” is a problem urgently needed to be solved in civil engineering design in China, and it is also a design specification for reinforced concrete structures (TJ 10-74 ) One of the remaining research topics. Our roof truss research team has reviewed a number of domestic and foreign documents, collected and studied some of the domestic reinforced concrete roof trusses experimental research data and papers, and began to work on some reinforced concrete trusses since 1976.
