摘要
采用桥梁专业软件MIDAS/Civil对一座下承式钢管混凝土拱梁组合结构进行空间有限元分析。通过共节点双单元法模拟钢管混凝土组合结构的受力,并参照新颁布《钢管混凝土拱桥技术规程》(DBJ/T 13-136-2011)进行结构验算。结果表明,该桥的各项指标均满足要求,并通过了施工监控和成桥荷载试验的进一步验证。
The bridge professional software MIDAS/Civil is adopted to analyze a concrete-filled steel tubular （CFST） arch bridge. The stress of the CFST is simulated by total nodes double-cell method, and the structure calculation is checked with the newly-promulgated regulation ＂Technical specification for CFST＂ DBJ/ T13-136-2011. The results show that the indicators of the bridge satisfy the re- quirements, and the results are further validated through the construction monitoring and bridge load test, etc.
