PREDICTION OF STRUCTURAL SAFETY AND LIFE OF REINFORCED CONCRETE STRUCTURES . PROCEEDINGS OF 3RD INTERNATIOAL CONFERENCE ON DETERIORATION AND REPAIR OF REINFORCED CONCRETE IN THE ARABIAN GULF, BAHRAIN, OCTOBER 21-24 1989. VOLUME 1.

A fracture mechanics technique is developed to predict the structural safety and life of reinforced concrete structural elements. This technique takes into consideration the crack propagation behaviour in concrete and reinforced steel bars. Various cracking mechanisms due to static and cyclic loading, stress corrosion, corrosion fatigue and environmental attacks are simulated. Fatigue and fracture data on steel and concrete are collected to obtain fracture parameters needed for the present model. These parameters include fracture toughness for steel and concrete and threshold stress intensity factor for steel. Based on the present technique, both residual life and strength of defective reinforced concrete elements can be predicted. This technique accounts for defect size and location, type of loading, structural system and service inspection.(A) For the covering abstract of the conference see IRRD 828897.
