Developing Damage Estimation Methods for Different Types of Reinforced Concrete Buildings

Abstract

The main purpose of this study is to develop a damage and loss estimation method for predicting earthquake damage in a possible earthquake. For this purpose; damage probability graphs have been drawn for 11 different types of reinforced concrete structures. in the study, 341 reinforced concrete buildings are grouped according to common features such as number of stories, age of the building, construction quality etc. A total of 11 different building groupings were obtained. All of the buildings are modeled by 3-D computer modeling and each was analyzed by nonlinear pushover analysis. Then, fragility curves for 4 different damage probabilities were plotted for each of the building groups using the data obtained from pushover analysis results. Total of 44 fragility curves were obtained for 11 different building groups. Using the fragility curves obtained by this study, it is possible to estimate the potential damage in any area of the buildings featuring similar characteristics.
