Abstract

Abstract

Currently, the connection of prefabricated steel beams often adopts the form of high-strength bolt end-plate splices. The beam components are manufactured in the factory and thus have high manufacture procision. When the beam components arrive at the construction site, high-strength bolts are used to complete the splicing, which is fast and convenient for installation. However, there are often assembly gaps between the end plates of prefabricated steel beams, and filler plates are often used to fill these gaps in the construction process. At present, there is no regulation in the design code regarding the influence of filler plates. In order to study the effect of filler plate on the bending stiffness and bending capacity of end-plate splice, finite element software ABAQUS was used to establish a solid element model of end-plate splice with filler plate, the complex contact relations between these components were set up. By considering the effects of thicknesses of end-plate and filler plate, the paper investigated the working mechanism of the tensile force transmitted by high-strength bolts, the position changes of the neutral axis, the stress state of the filler plate, and the ultimate stress state of the end-plate in the tensile zone. The analysis results indicated that for the H-section steel beam H400×200×8×13 and filler plate -400×200×t_p1(t_p1=12-24 mm), the initial bending stiffness of the end-plate beam splice increased with the increase of the filler plate thickness, when the filler plate thickness was within 15 mm, the bending capacity of the end-plate beam splice was not significantly influenced by the filler plate thickness.
