The current research examines the seismic performance of irregular cross-section of bridge piers that has rarely been investigated. Preceded by a successful validation, the study was numerically conducted by ABAQUS/Explicit program containing a comprehensive series of FE bridge piers under unidirectional cyclic loading and axial dead load. Three co...

The current work presents a unique study on the seismic performance of innovative corrugated-plate steel bridge piers. While several previous research was conducted on steel tubes with cross sections such as rounded or semi triangular plates, the seismic performance of such structural members with straight ribbed corrugation geometry under uniaxial...

Presented are the results from a finite element model of steel–concrete composite beams with deep decks and a comparison with various analytical/design methods. Using a deck deeper than 80 mm are becoming popular with a desire for longer spanning capability and lower concrete volume. However, there are no design rules in either American or European...

This research involved modelling 146 push-off tests using ABAQUS/Explicit package to study the behaviour of composite beams with both narrow and wide parallel ribbed deck. The most significant finding of this research indicated a non-direct relationship of the rib deck ratio with the shear connector resistance, contrary to it was believed in the pa...

Three-dimensional finite element push-off models were conducted by ABAQUS/Explicit package. This study aims to enhance the strength and ductility of shear connection in deep profiled decking of 146 mm. Two steel reinforcement techniques were investigated which are double wire-mesh reinforcement and embedding steel bars within the ribs at different...

This research investigated the effect of large stud of 22 mm in diameter on the performance of composite beams with 146 mm deep decking oriented perpendicular to its axis. Three-dimensional finite element push-off tests were modelled using ABAQUS/Explicit package to determine the load-slip capacity of shear stud and the concrete failure patterns in...

Project objectives and goals Trapezoidal profiled sheeting is widely used in composite beams. A profiled sheeting comprises of trapezoidal shape that lies between the concrete slab and the steel beam. It can be oriented either parallel or perpendicular to the axis of the steel beam and fixed by headed stud connectors. The profiled sheeting works as...
