Abstract Seismic structural fuses such as buckling restrained braces (BRBs) are highly nonlinear members that need a detailed finite element model (FEM) to represent their actual behavior. On the other hand, making for whole building from solid or shell elements be consistent with of BRBs would require expensive computational time and large storage space especially when performing history analy...

60 A practical approach to the optimal design of precast, prestressed concrete highway bridge girder systems is presented. The approach aims at standardizing the optimal design of bridge systems, as opposed to standardizing girder sections. Structural system optimization is shown to be more relevant than conventional girder optimization for an arbitrarily chosen structural system. Bridge system...

The box girder can be seen as a kind of simplified ship structure that withstand vertical bending moment. Dynamic loads play an important role in structural safety analysis, such bow slamming during harsh sea conditions. In this paper, the dynamic elastic–plastic response and ultimate strength under moment are analyzed. A with same cross-section scantlings span length Nishihara experiment is se...

This work performs an investigation into the optimal position of two longitudinal stiffeners with different cross-section shapes such as open section (L-shaped and T-shaped) closed (rectangular triangular shapes) stiffened plate girders under bending loading through optimization procedure using a gradient-based interior point (IP) algorithm. The stiffener optimum locations are found by maximizi...

The West Gate Bridge, intended to span the Yarra River in Australia, collapsed during its third year of construction in 1970. Investigation into the project revealed numerous issues in the bridge's design and construction. The West Gate Bridge is one of a number of box girder bridges built during the mid 2 0 th century, and was one of four to fail in a three year period. An overview of the desi...

One of the goals that the Innovative Bridge Research and Construction (IRBC) program, sponsored by the Federal Highway Administration (FHWA), wishes to achieve through sponsored research projects is the concept of an economical, durable, short-span bridge that reduces construction time. Delaware County, Iowa took a step in that direction through the construction of a 64 ft. long bridge comprise...
