| 摘 要： | 本文提出的方法是直梁桥荷载横向分配理论中“刚接板法”的推广,它根据曲线梁的特点,提出了等作用半波正弦荷载的概念,并采用了内力横向分配概念。该方法充分考虑了曲线梁横截面构造上可能的不对称性及横截面的弹性变形。文中阐述了开口截面曲线梁桥最大活载内力的计算方法,并附有实桥算例。

| Abstract: | The method presented in this paper is an extension of the rigid-joint-plate method about load distribution of straight girder Bridge,and also is applicable for plane-curved ones.Its main points introduced is the principle of equivalent half-wave sinusoidal load according to the behaviour of curved girder and adopting the concept of transverse distribution of internal forces. The unsymmetric and elastic deformation of cross-section of girder are fully considered.Calculation of the maximum internal forces under live load are described and illustrated in detail by example from real project. |
