“…If the composite floor is placed on steel girder, it will have no connector to resist against longitudinal shear force, and the concrete floor cannot carry bending moment. Yang and Su [8] studied the effect of fatigue on the composite bridges. Kim et al [9] investigated the flexural behavior and corresponding load rating of the simply-supported steel I-girder bridges subjected to military truck loads.…”

Bridges are among very important structures in engineering, due to their rather high cost, and this is why optimization of these structures is a challenging problem. In this paper, optimal design of steel-concrete composite I-girder bridges is performed. Three recently developed meta-heuristic algorithms consisting of Colliding Bodies Optimization (CBO), Enhanced Colliding Bodies Optimization (ECBO) and Vibration Particle System (VPS) are utilized for the first time in the optimal design of steel-concrete I-girder bridges. Both continuous and discrete variables are utilized in the process of optimization. Performance and the convergence histories of these algorithms are compared. In order to have a suitable comparison between these algorithms with previous algorithms, PSO is used and results are displayed. This paper focuses on cost optimization the bridges. Furthermore constraints include all of requirements of the code of practice for design. The comparative study has shown that VPS algorithm has better performance than CBO and ECBO. However, all three algorithms act in a way that the final optimized design does not need the addition of the longitudinal stiffener.

The landscape is very important for the overpasses and other bridges built in the city. Not only should it be integration with land, sky and surrounding scenery, but also reflects the city's humanities content and historical background. Structures with landscape features, of which the forces are different from the normal structures, often have rather special characteristics. To ensure the safety of these structures, the test is often needed, and of course a lot of test equipments, sites and costs etc are required.Without the need of test sites, testing instrument, and test model fabricating, the simulation analysis, which could get better effect than actual model test in some cases, has been extensively applied in lots of industries, such as machinery manufacture, aerospace, civil engineering, etc. Be great reference value for the design of the bridge, the simulation process and relevant conclusions of a curve pier in Hefei (the flower city in China) are described in this paper.
