Failure Analysis of RC Structures Using Irregular Lattice Models

Abstract

This paper develops Irregular lattice models as an alternative means for failure analyses of reinforced concrete (RC) structures. The paper describes fundamental aspects of the model and comments on its use in promoting the iterative design of RC structures. Simulation results are provided for RC structures under quasi-static, monotonic loading. In particular, results are given for the incremental lateral load analysis of a 1/3 scale model of a lightly reinforced shear wall structure. Preliminary work on extending the model to accommodate dynamic loading is described.
