Prediction of seismic damage in reinforced concrete frames

In practice, damage in reinforced concrete buildings is qualitatively measured in terms of ductility demands. In the present study a more rigorous model of member damage in reinforced concrete buildings is set up. Analytical models for inelastic behavior of reinforced concrete members are used to analyze a set of static cyclic load tests. Other damage indicators, such as dissipated energy and cumulative plastic rotation, are measured for each test. Results for the sample are then used to develop a stochastic model of damage in reinforced concrete members. Final results are in terms of probabilities of local failure in a building frame subjected to a given earthquake. A model for computing the system reliability as a function of correlation between member resistances is also presented. Thesis Supervisors: John M. Biggs Title: Professor of Civil Engineering H. M.
