Simulation of cyclically loaded concrete structures based on the finite-element method

The finite-element method for simulating the nonlinear behavior of reinforced concrete structures has progressed to the point where it is close to being a practical everyday tool for design engineers. Further advancements have made the analysis of arbitrary loading conditions, including reverse cyclic loading or earthquake-type loading, feasible. Recent criticism has questioned the practicality, reli- ability, and robustness of the finite-element method due to perceived complexities involved in developing the model and interpreting the results. A series of analyses are presented on reinforced concrete structural walls of varying height-to-width ratio, varying wall cross section, and varying levels of reverse cyclic loading to demonstrate that the finite-element procedure is capable of providing quick and reliable simulations, while employing simple modeling techniques. The modeling herein utilizes low-powered rectangular membrane elements, and material properties are smeared within the elements. Behavioral aspects such as ultimate strength, displacements, postpeak ductility, energy dissipation, and failure mechanisms are well simulated.
