“…However the final choice for the materials applied mainly depends on the costs. In 2002 Ramböll were given the assignment to design a highway bridge carrying the highway E4 over a national road in mid Sweden [Collin et al 2002]. Three alternatives were studied, namely 1) A haunched three span I-girder bridge in carbon steel 2) A haunched three span I-girder bridge in duplex stainless steel..…”

“…The use of lateral bracings is however more widely different and is often used for stabilization of horizontal loads, like wind loads and is then called wind-bracings [1]. They could also be used as stabilization in the construction stage where the bracings are connected between the top flanges of the steel girders to secure the lateral stability of the system [1]. Not so widely used, or at least not to the authors knowledge, they can be used to distribute vertical…”

“…A solution to design an economical bridge is to use the principal of a steel-concrete girder system. For this type of bridge, the two materials (concrete and steel) can effectively be optimized and use where they are most suited [1]. The concrete is used as an overlaying slab carrying the live load which is distributed on the steel girders.…”

The ways of designing and building steel girder bridges with a composite concrete deck vary much between different parts of the world. A bridge system with twin steel I‐girders or a concept with multiple (more than two) girders can be used. The design and use of details and secondary systems also vary a lot. In order to give horizontal stabilization and distribute horizontal loads, bracing between the I‐girders bracings are often used. Although not so common, the bracing can also be used to distribute vertical loads between the main girders. To describe and to analyze the possible impact from using a lateral bracing, this paper describes the design of a curved bridge in Guatemala City and its challenges. The new Bridge over the Pinula River is designed as a steel‐concrete composite bridge with multiple steel girders with a concrete deck on top and has lateral bracing between the girders. The bridge is used as a case study to analyze the impact from a lateral bracing system on the vertical load distribution between the longitudinal girders. The bridge was designed with lateral bracing between the top flanges along the whole bridge and with bracing between the lower flanges near the supports. The case study shows that the distribution of eccentric vertical loads between the longitudinal girders can be improved by using lateral bracing between the lower flanges for multiple girders. In some cases, it may not be beneficial to use lateral bracings along the whole bridge length, like for example this bridge. In this case due to the governing design cases in the construction stages where these bracings influenced the torsional stiffness of the bridge in such way that an unfavorable distribution of the support reactions between the six girders at some supports was achieved.

“…Integral bridges have proved to be a very good alternative to the traditional girder bridges when used for structures with one or more short and middle spans. [1][2][3][4] However, the constructional simplicity of integral bridges involves complexity in the design. Both the superstructure and the substructure should be merged into a single static model because of the framed connection.…”

Soil–Structure Interaction of Integral Bridges

The design of integral bridges brings some specific problems, especially the problem of soil-structure interaction. This paper describes an original method to deal with this issue. Soil-structure interaction is simulated by soil springs introduced into a static model of the integral bridge. The method provides general formulas to calculate the stiffness of the springs as modules of subgrade reaction. The described method is specifically tuned for applicability in civil engineering practice.
