摘要
梁格法是桥梁结构空间分析的一种有效方法,但传统的梁格法无法合理模拟装配式斜交板桥的铰接缝作用,这使得其在分析装配式斜交板方面受到一定的限制。根据梁格法原理,通过使虚拟横梁在同一铰接缝处的梁端竖向约束相互耦合来模拟纵向铰接缝,提出了改进的梁格模型,建立了装配式斜交板桥空间分析模型并编制程序进行了计算,最后对计算结果进行了分析,为斜交桥的设计计算提供参考。
Although grillage method is an effective method of analyzing bridge deck, it has not been widely used in analyzing asembly skew slab for the restriction of that the traditional method can＇t be used resonablyin simulating the hinged joint. Based on basic principles of grillage method,an improved grillage modal of making the vertical constraint of cross beam ends couple at the same hinged joint to simulate longitudinal hinged joint is brought forth, establish the space analytical modal of assembly skew slab bridge and compute the modal using the self-generator program composition. This method may provide the reference for the design of the asembly skew slab bridge in the future.
