It has been argued that the AASHTO LRFD design code for maximum live loads on highway bridges is overly conservative. In an attempt to determine the level of conservativeness, if any, the writers developed a methodology incorporating real-time visual data collection from traffic cameras coupled with structural strain response of girder bridges. Average daily truck traffic along with frequency o...

The shear panels of plate girder made from corrugated in the web is investigated this research. A beam attached zone as part an experimental and theoretical investigation into girders. In experiments, seven specimens were tested under two points load. Six them different shape web, last specimen was without corrugation a reference called control. study effected (corrugation plate, thickness with...

Background of the research: A conventional box-type structure is generally used in constructing core/shear wall, internal frame, and steel box girders. Tube-in-Tube with single multiple tubes reduces shear lag effect lateral deformation a tall tubular structure. Purpose: However, present study focuses on behavior modified form beam, i.e., beam outstanding flanges. Thus, this analyzes flanges co...

This paper presents finite elements for a higher order steel–concrete composite beam model developed the analysis of bridge decks. The accounts slab–girder partial interaction, overall shear deformability, and shear-lag phenomenon in steel concrete components. theoretical derivation solving balance conditions, both weak strong form, is firstly addressed. Then, three different are proposed, whic...

Distortion-induced fatigue cracking in unstiffened web gaps is common in steel bridges. Previous research by the Minnesota Department of Transportation (Mn/DOT) developed methods to predict the peak web gap stress and maximum differential deflection based upon field data and finite element analyses from two skew supported steel bridges with staggered bent-plate and cross-brace diaphragms, respe...

this paper describes experimental and numerical investigations on two specimens of frames composed of steel reinforced concrete beam and angle-steel concrete column under horizontal low cyclic loading. based on the test results, the relationship curves of the horizontal load-displacement and the failure modes are acquired. meanwhile the hysteretic behaviors, skeleton curves, stiffness degradati...
