Geometric imperfections such as radial imperfection, diamond shape, and local dimples could affect the buckling mode and load carrying capacity of axially compressed steel tubular columns. This paper experimentally investigates the effect of radial imperfection on the load carrying capacity of tubular columns. Test samples include 100 specimens with different values for diameter, length, thickn...

corrosion of steel reinforcement is one of the most prevalent causes of reinforced concrete (rc) structures deterioration in chloride-contaminated environments. as a result, evaluating the impact of any possible corrosion-induced damages to reinforced concrete bridges strongly affects management decisions: such as inspection, maintenance and repair actions. the corrosion propagation phase is a ...

Abstract With the increase of steel structure bridges, design bridges begin to evolve in direction high quality, precision, and short period. In order improve quality efficiency spatial integration technology structural performance evaluation 3D is studied. Firstly, carried out based on rapid method, then finite element simulation conducted by software analyze its optimize model. The research r...

The presented innovative steel-concrete-steel composite (SCSC) plate is being researched at TU Wien, Institute of Structural Engineering, Research Unit Steel Structures. research aim to use the SCSC for single-track short-span railway bridges in Austria. projected be a load-bearing structure transverse direction, transferring loads main steel girders cross section. Based on finite element analy...

This paper focuses on Load distribution factors for horizontally curved composite concrete-steel girder bridges. The finite-element analysis software“SAP2000” is used to examine the key parameters that can influence steelgirders. A parametric study conducted load characteristics of such bridge system due dead loading and AASHTO truck using finite elements method. considered in this are: span-to...
