Experience from past earthquakes indicates that some structures perform better than others under similar ground motion conditions. This disparity leads to the conclusion that some structures will be safer, and thus less likely to require repair or cause harm, than others. In order to describe this phenomenon quantitatively, vulnerability functions are developed. Vulnerability functions describe a structure in terms of its likelihood (probability) of exceeding a certain limit state at a specified ground motion condition accounting for the uncertainty in both excitation and structural capacity. Indeed, there are several sources of uncertainty that cannot be eliminated, but in order to create the most accurate relationship possible, any uncertainty that can be reduced, should be reduced. Therefore, the goal of this particular part of this project is to remove some of the uncertainty in the nature of the buildings that are being modeled. By understanding better of a typical unreinforced masonry (URM) building, it is possible to accomplish this goal and create a vulnerability function which may better describe a larger percentage of the population of URM structures in
Mid-America.
