“…The mid-span of 40m is steel box girder with uniform section. Before pouring concrete, sear nails should be welded in top surface to resist the effect of loading and maintain the wearing resistance and the durability [4][5][6] . Since the rigidity of concrete girder is great larger than that of steel girder, added more diaphragm plates enhance the rigidity of the steel girder.…”

A steel-prestressed concrete composite continuous beam bridge is one of new type navigational bridge structures with economic and clear mechanic behaviors. The junction of steel and concrete beam is the critical part, which makes the two different materials to be continuous structural system and transfer different kinds of loads reasonably. This article takes the Chang Bridge which locates on G318 state road in Changxing County, Zhejiang Province as the background to analyze the characteristics of transferring bending moment in the junction by the finite element method. The results show that the junction of steel and concrete designed can transfer loads smoothly. Therefore, the junction can be further researched for extensive application.

“…For example, Li and Ge (2005) studied the seismic responses of a five-span half-through CFST arch bridge. The seismic response analysis of a multi-span and long-span cable-stayed bridge was done by He et al (2009), Jin et al (2012), and Sun et al (2016). It was found that the effects of the vertical component on the bridge response were remarkable.…”

The occurred damages during the past significant earthquakes have proved that vertical seismic excitation has tremendous effect on bridges. Three-component earthquake excitations are preferred to resemble the earthquakes. In this article, a cable-stayed arch bridge, a new type of bridge with the hybrid system of half-through arch and stay-cables, was analyzed under a set of different earthquake excitations (more than 21 ground motion records). Both vertical and horizontal components of the ground motions were considered to act simultaneously at the bridge supports. By using different three-component earthquake excitations, the dynamic responses of the bridge, including the displacements and accelerations of the main parts of the bridge, were obtained. The effects of various parameters such as soil type, epicentral distance, spatial variation of the ground motions, and dimensional variation of the structure were investigated. The results of the numerical study indicate that the cable-stayed arch bridge subjected to both horizontal and vertical components of earthquakes are more vulnerable than those subjected to horizontal ground motion only.

“…Cable-stayed bridges are widely used because of their large spans, beautiful appearance, light weight, and good seismic performance. As bridge spans have increased, single-and twintower cable-stayed bridges have become increasingly unable to meet the associated demands, and multitower cable-stayed bridges have become more commonly constructed [1][2][3][4]. e mechanical behaviors of multitower cable-stayed bridges and single-or twin-tower cable-stayed bridge are considerably different.…”

Based on the stiffness limitations of the midtower in multitower cable-stayed bridges, a new stiffening system (tie-down cables) is proposed in this paper. The sag effects and wind-induced responses can be reduced with the proposed system because tie-down cables are short and aesthetic compared with traditional stiffening cables. The results show that the stiffening effect of tie-down cables is better than that of traditional stiffening cables in controlling the displacement and internal force of the bridge based on a static experiment and finite element analysis. Therefore, the proposed system can greatly improve the overall stiffness of a bridge, and its stiffening effect is better than that of traditional stiffening cables in controlling the displacement and internal force. The results provide a reference for the application of such systems in practical engineering.
