Abstract

A one-dimensional two-node layered composite beam element with bond-slip effect is extended in this paper for nonlinear finite element analysis of FRP-reinforced concrete beams under a combined mechanical and thermal loading. The element has two nodes and four degrees of freedom per node. Bond-slip between reinforcements and the surrounding concrete is permitted in the numerical model. BPE Modified Model is employed to account for bond strength of FRP reinforcing bars under fire conditions. A nonlinear finite element analysis based on heat transfer theory is performed to determine the temperature distribution in the cross section of the beam. Both geometric and temperature-dependent material nonlinearities are accounted for. The proposed element is validated by a numerical example and the computed results for the numerical example from this model are compared with those obtained from the model with perfect bond assumption, and research findings are summarized and concluded.
