Elaboración de curvas de fragilidad para ensayos experimentales realizados sobre mamposterías de bloques de concreto y ladrillos en Quito

Abstract

The present work will help to understand better the behavior of the nonstructural masonry in Quito, through the collection of data on frame systems with block and brick filling panels, complementing them with analytical models that represent a behavior similar to the reality with the help of tests of walls made in the CIV. It is known that by the action of lateral or seismic loads cracks begin to appear in the masonry, for which the main levels of damage are established: mild, moderate, severe, collapse, for both block and brick. Considering the variation of the rigidity or change of slope in the capacity curves, the points showing the different damage states are obtained. With the obtained database an analysis is made with the lognormal probability distribution function, which is suitable for this study since it covers fundamental parameters that allow relating different variables and thus be able to elaborate and obtain the fragility curves, they are of great benefit for the field of seismic engineering in which the vulnerability of structural systems can be estimated due to pathologies presented by the masonry.
