Abstract: Based on the high order nonlinear membrane elements presented in Reference , the formulation of a higher order rectangular 14 noded RC Plate element is proposed for the analysis of RC panel walls. The nodal DOF of the element presented are assumed to be in plane displacements u, v; transverse deflection w and cross section rotations ψ x, ψ y , and their derivatives (with respect to x ). Of the element displacements consequently are 3rd order Hermite polynomial in the x direction and ...

Key words: higher order plate element, smeared rotating crack model, geometric nonlinearity
