Abstract The effects of opening parameters on the bending behavior of fixed open-web steel beams under static loading were experimentally investigated using six specimens of different opening length-to-height ratios, area ratios, and distributions. The experimentally obtained failure modes, bearing capacities, and load-displacement curves of the specimens were compared with those extracted from numerical simulations performed via Abaqus finite element analysis software. The results revealed the following: (i) The typical failure mode of the fixed open-web steel beams was plastic failure at the opening corners in the shear-bending sections, with compressive corners experiencing flexion and tensile corners More >

Abstract One of the most common methods of strengthening concrete structures is the use of composite fibers such as FRP. These fibers have found a special place in structural retrofitting methods due to a number of specific ability including lightness and ease of performance. Reinforced concrete structures have long been considered by design engineers for the possibility of retrofitting high strength composite steel structures. In this study, twenty-two steel beam models were modeled by ANSYS software. Variable parameters studied in the modeled steel beams can be referred to the number, orientation and thickness of composite layers. More >
