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...

Structural response of quay crane should take more attention with the growth worldwide logistics demand and size. This paper analyzes mechanism metallic structure induced by trolley traveling. An on-site test has been conducted. The time domain girder acceleration signal shows that main influence traveling on is high-frequency impact passing through hinge point. spectrum frequency vertical vibr...

The safety risk events that may occur during the cast-in-situ process of a concrete box girder an interchange bridge with high piers in mountainous areas are briefly listed. Based on backgro...

Abstract Box girders bridges are widely used in modern highway systems because of their efficiency and attractive appearance. Vehicles loads represent one the mainly factors that influence structure reliability box bridges. Calculation bridge resistance with different stress due to vehicles as close possible real ones constitute premise a correct design structure. The goal this study is realize...
