| 摘 要： | 为了研究由于施工产生的误差对结构可靠度的影响,针对铜管混凝土拱桥的特点,采用应力叠加法(也即极限状态设计法)模拟了钢管混凝土拱桥成桥过程,运用响应面法结合FORM计算了结构体系可靠度.分别计算了拱桥拱轴线设计高度及拱轴线下降0.3 m两种荷载工况下的结构体系可靠度.计算结果表明按1/2跨截面影响线布载时桥粱的可靠指标最...

| Abstract: | In order to study the effect on structural reliability of concrete-filled steel tubular(CFST) arch bridge due to construction errors,aiming at the characteristics of CFST arch bridge,using the stress superposition method(limit state design method) to simulate CFST arch bridge construction process,the structural reliability of CFST arch bridge is studied by using the response surface method(RSM) combined with the first-order reliability method(FORM).The structural system reliability of CFST arch bridge under... |
