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...
I am modelling this design in ABAQUS to simulate a push-out test for composite beam. When the analysis finishes, the concrete slab massively distorts as shown in Pic.2 even though no applied load or any other effect is subjected to the concrete slab.
I tried making changes in boundary conditions, time scale factor, even interactions but I have got the same phenomena.
Any suggestion please?
Please, would someone help me with that step. Actually, when I submit my model to be analyzed, the time of analysis is very short (less than a minute).
So, I would like to make it much longer in order to give me a reasonable results. Any advice to deal with that?
Note: I attached two pictures for that step.
I am modeling a push-up sample regarding the composite beam. I need to apply a magnitude of load without inserting a specific amount of load or even displacement, and eventually come up with the reaction force and displacement.
I think the way to deal with this is using the Velocity/Angular velocity option in the boundary condition. How can I deal with this option.
Note: the sample I am dealing with is attached with this message
