Non-linear Finite Element Analysis of Bolted Side-plated Beams

Abstract:

Based on the experimental study of 4 bolted-side plates (BSP) beams, a numerical finite element analysis using OpenSees was conducted on the entire loading process and the shear failure of BSP beams.The nonlinear behaviors of materials and slip model on the interface between steel plate and concrete beam were taken into account. The results of the finite element analysis were found to be in good agreement with the experimental results. The main parameters affecting the behavior of BSP beams were analyzed, including the number of rows of anchor bolts, anchor bolt spacing along the beam, steel plate depth, steel plate thickness, yield strength of steel plate, anchor bolt diameter, concrete strength and so on. The results show the influence of the parameters on the shear bearing capacity, longitudinal and transverse slip, which provides basis for the strengthening design of BSP beams.
