摘要: Abstract A new layered 4-node, 24-degrees of freedom rectangular composite plate element is developed in this paper for nonlinear finite analyses FRP-strengthened RC slabs. The approach used to form an integrated modelling concrete, FRP, adhesive layer and steel reinforcement with a perfect bond assumption between each layer. Timoshenko’s beam functions are employed describe the bending behaviour shear locking problem avoided naturally. Geometrical material nonlinearities both included element. proposed simple demonstrated be accurate efficient analysis structural Once validated, also investigate effects parameters, including types FRPs strengthening scheme on
