Abstract

THE OBJECTIVE OF THIS WORK IS TO PROVIDE A RELIABLE NUMERICAL MODEL USING THE FINITE ELEMENT METHOD (FEM) FOR THE STATIC AND DYNAMIC ANALYSIS OF REINFORCED CONCRETE (RC) SHELLS. FOR THIS PURPOSE TWO INDEPENDENTLY COMPUTER PROGRAMS BASED ON PLASTICITY AND VISCOPLASTICITY THEORIES ARE DEVELOPED. THE WELL KNOWN DEGENERATED SHELL ELEMENT IS USED FOR THE STATIC ANALYSIS UP TO FAILURE LOAD, WHILE 3D BRICK ELEMENTS ARE USED FOR THE DYNAMIC APPLICATION. THE IMPLICIT NEWMARK SCHEME WITH PREDICTOR AND CORRECTOR PHASES IS USED FOR TIME INTEGRATION OF THE NONLINEAR SYSTEM OF EQUATIONS. TWO BENCHMARK EXAMPLES ANALYZED BY OTHERS ARE SOLVED WITH THE PRESENT NUMERICAL MODEL AND RESULTS ARE COMPARED WITH THOSE OBTAINED BY OTHER AUTHORS. THE PRESENT NUMERICAL MODEL IS ABLE TO REPRODUCE THE PATH FAILURE, COLLAPSE LOADS AND FAILURE MECHANISM WITHIN AN ACCEPTABLE LEVEL OF ACCURACY.
