| Description |
It is possible to quantify the damage to reinforced concrete members under cyclic loading through a nondimensional parameter known as a "damageindex. The damage index can be either a global damage index for the total structure, or a local damage index for the element level. In this paper, the limitations of existing local damage models are discussed. A new damage model is proposed, which is consistent with accepted definitions of ductility and which takes into account at least two equal amplitude cycles at each displacement level. A total of 23 reinforced concrete beam elements were tested under monotonic and cyclic loading up to, the ultimate failure of the specimens. Based on the test results, a simple relation termed "modified Park's model." has been suggested for evaluation of the damage index. The proposed model predicts 100 percent damage at the ultimate failure state of the element . The proposed damage index model can be extended to other structural elements, such as shear walls, columns, beam-column junctions, etc.
