Abstract:
A conceptual model is presented for assessing the state of health of cracked reinforced concrete (RC) structures. The model consists of a crack based approach that links crack displacement measurements acquired on site to the structure’s strain state and stress state, and allows for the determination of the structure’s reserve capacity. The model is entirely formulated in terms of equilibrium, compatibility, and stress-strain relationships, and can be used to effectively assess the reserve capacity of RC membrane elements subjected to arbitrary in-plane loads.
