Outline of Final Research Achievements

A new formulation considering a finite rotational displacement is developed in the ordinary Rigid-Body-Spring Model (RBSM) in order to simulate large displacement and rotation collapse behavior of RC structure. In the proposed formulation, a finite rotation matrix by using axial vector is applied. The model is found effective, however, showed unnatural deformation behavior in a range of large rotation. Therefore, a new discrete analysis model is further developed based on the equivalence between RBSM and linear Timoshenko beam with applied reduced integration scheme. It is confirmed that this proposed model can simulate the large rotation behavior of concrete and RC structure including the localized failure behaviors.
