Development of Fragility and Vulnerability Functions for Reinforced Masonry Structures in Mexico: A Case Study

The north of the state Baja California (BC) is located in one regions Mexico with a high seismic risk. predominant infrastructure city Tijuana consists reinforced masonry housing structures, making it crucial to understand dynamic behavior this type structure. Using “Vulnerability Modeller’sToolKit” (VMTK), fragility functions were obtained for low, medium, and levels design. It was found that probability achieving or surpassing different damage states (light, moderate, extensive, complete) low-height (1–3 floors) an expected value 0.50 g PGA medium-height (4–7 0.5 SA (T = s).Vulnerability derived, determined that, low design level, respectively presented loss rates 30% 44% s). These vulnerability can be used estimate losses future risk scenarios, thereby reducing uncertainty analysis calculations Tijuana.
