摘要
应用结构力学理论,考虑荷载横向分布的影响,得出对于不同截面形式的主梁在外荷载作用下的跨中挠度的计算方法。并结合实际的工程实例进行验证,将计算的跨中挠度值与实测的跨中挠度值进行比较,满足规范要求,则表明采用该方法来计算既有桥梁的挠度是可行的。
Application of the mechanical structure of the theory, consider the lateral load distribution, to come to different forms of cross-section of the outer girder load deflection in the cross-calculation. In the light of actual examples to validate the project will be calculated in cross-deflection and measured deflection in the cross-values to satisfy regulatory requirements, show that the method used to determine the deflection of the existing bridge is feasible.
