| 摘 要： | 以一座典型的具有中央分隔带的中承式3跨(20m 60m 20m)连续梁拱组合式桥梁为背景,提出了弹性支撑连续梁计算其荷载横向分布的方法,并对其静动力性能进行了空间有限元分析和试验研究,结果表明:理论计算值与试验结果基本吻合,所提出的荷载横向分布的计算方法能较好地预测其内力分布。

| Abstract: | Based on a typical three span half-through prestressed continuous beam-arch combination bridges,the elastically supported continuous beam method for calculating the load lateral distribution of this bridge is presented.The static and dynamical behavior is analyzed by spatial finite element method and the experimental study is completed.There is a good agreement between the theoretical values and testing results.The presented calculating method of the load lateral distribution can better predict the internal force and its distribution of this bridge. |
