连续弯梁(刚构)桥的统一计算模式

Unified model for continuous curved girder bridges

对连续弯梁 (刚构 )桥的支承类型进行了深入分析 ,将各种支承形式都拟化成两个弹性抗转动支承和一个竖向弹性支承 ,并通过 8自由度曲杆单元模式 ,形成连续弯梁 (刚构 )桥的统一计算方法。最后给出一个算例 ,并用

In this paper, a model is presented for the calculation of continuous curved girder bridges after completely classifying the bridges, considering all kinds of supports as a system which contains three elastic supports of Y axis(reaction), X axis(moment) and Z axis(torsion) and applying for curved pole element model of eight freedom degree. In the end, a numerical example is given and verified by general program SAP.
