Use of Generalized Beamgrid Method to Calculate the Radius Vector Load Lateral Distribution of Curved Beam Bridge

阐述了用广义梁格法计算弯梁桥的径向水平荷载的原理，用结构分析程序ＳＡＰ９３建立的空间梁模型验证了理论的可行性和准确性，并且分析了径向水平荷载对主梁内力的影响．

This paper studies the principle of calculating radius vector load distribution of curved beam bridge by using generalized beamgrid method and the space beam model built with structure analytic program SAP93 to prove the possibility and accuracy of the theory. It also analyses the effect of radius vector load on main beam.
