Abstract
Verification of the proposed RC constitutive model stiring multi-directional cracks up to 4-way is conducted on stress field of RC structure which has non-uniform and different stress paths on each point. RC nonlinear FEM analyses which are object of comparison with statically loaded shear wall test, international blind benchmark analysis of dynamic shaking test of 5 story shear wall building and comparison with test of scale-down models for real structures are carried out. Further analysis of multi-directional cracks on box-type shell structure which is subjected to multi-directional loading is examined. These results confirm good performance for predicting highly nonlinear behavior of RC structures, and also show fair applicability and future enhancement for structural analysis by FEM.
