“…Limited studies have also been performed on the connection details of cross-frames [27] and the effect of lateral bracing and buckling of main girders after a fracture. Four types of cross-frame connection details, including the use of end-plate connection, connection plate and split-tee connection were experimentally investigated by Takahashi et al [28]. Kozy and Tunstall [29] conducted stability analysis on a steel girder bridge.…”

In steel girder bridges, fracture of one girder may occur without noticeable bridge profile changes. It is critical to ensure that the bridge will have adequate capacity to prevent collapse until the next cycle of inspection discovers the damage. It is realized that once one of the bridge girders is fractured, vertical loads need to be distributed through an alternative path to the intact girder(s). In this case, cross-frames can play an important role in transferring the loads and preventing from sudden collapse. This paper investigates the impact of cross-frames on load distribution after a fracture is occurred in one girder. Bridge configurations with different cross-frame spacing were studied using finite element modeling and simulation of the bridge behavior with a fractured steel plate girder. Nonlinear and dynamic solution methods were used for these analyses. Results of this investigation demonstrated the important role cross-frames can play in providing some reserved capacity for the bridge with fractured girder to enhance the bridge redundancy. The contribution of the cross-frames and the behavior of the bridge after fracture in one girder however depends on the configuration of the bridge. A study of the variation of the effect of cross-frames with respect to the number of girders is also included in this paper.

“…This type of joint consists of short bolts and connected plates called tee flange plates. Although this is often used for buildings, in bridge engineering field the use is limited in connecting main girders and cross-beams of rationalized bridges with a few main girders [4].…”

“…Limited studies on intact twingirder bridges were also performed, mainly focusing on connection details of diaphragm, buckling of main girders, shear-lag effect in slabs etc. Takahashi et al (1997) performed an experimental study to investigate the structural details of the connection of diaphragm used in the first steel twin-girder bridge "Horonai River Bridge". Four types of connection details, including the connection with triangular rib plate or connection plate, split-tee connection and endplate connection, were investigated.…”

Experimental Study on Steel–Concrete Composite Twin I-Girder Bridges

A large number of steel-concrete composite twin I-girder bridges have been built in both Europe and Japan, but the lack of redundancy has always been a concern in the U.S. and many other countries. In addition, very few experimental studies have been performed on mechanical performance of such bridges, particularly for the intact twin I-girder bridges. On this background, a steel-concrete composite twin I-girder bridge specimen was designed according to the current highway bridge design specification in Japan. The static loading tests were performed, and two loading conditions including both symmetric loading and asymmetric loading were applied. Load versus deflection relationship and strain development on steel main girders and concrete slab at key sections were measured. The flexural strains on the lateral beam were also measured and reported in this paper to confirm the load transfer between two main girders. In addition, the shear strain of shear connectors (stud, in this study) was also measured to investigate the shear force transmission on the steel-concrete interface. The theoretical values were also provided to compare with the test results from the twin girder specimen under symmetric loading condition. The experimental results indicate that the theoretical analysis can predict the behavior of the twin-girders very well in the elastic stage by considering the effective width of the slab. Performance of each structural components and load transfer paths in such bridges were also discussed.
