摘要 对中华人民共和国行业标准JGJ/T249-2011《拱形钢结构技术规程》(以下简称《拱》)中拱形钢管混凝土结构相关的承载力实用计算方法进行了论述。对已有拱形钢管混凝土结构的试验数据采用《拱》进行计算,结果表明按照《拱》计算的承载力结果与试验值较为吻合。同时选取典型算例,进行拱形钢管混凝土结构与相应空钢管结构的承载力对比设计,结果表明在拱形钢管结构的弦管内部填充混凝土对结构的承载力有较大提高。 According to the design code "Technical Specification for Steel Arch Structure", this paper discusses the design method of concrete filled steel tube (CFST) arch structures. A comparison of results calculated using the design code with the tested CFST arch structures shows that the former has a good agreement with the test results. Typical example was presented, comparing the bearing capacity of CFST arch structures with corresponding steel arch structures. The results indicated that the bearing capacity of CFST arch structures filled with concrete was improved considerably over that of hollow steel arch structures.
