    Ecuador is located in areas of high seismic hazard due to its location on the Pacific Ring of Fire. For this investigation, an estimate of the probability of exceeding a certain damage level of the Block 1 parking lot was made by developing fragility curves upon collapse using a nonlinear dynamic time history (ADNL TH) analysis and considering incremental dynamic analysis curves. This investigation followed ASCE 41-17, FEMA P 58, and NEC 2015 guidelines. Through a spectral modal analysis, noncompliance with the strong column-weak beam criterion and torsion of the building in the second vibration mode was observed. The results witnessed a high probability of structural damage to the parking lot or collapse in component 2 (NS), with maximum nonlinear drift responses that do not reach the performance level for immediate occupancy (IO) and life safety (LS) for a return period of 72 years and 475 years. In addition, a total of 218 nonlinear dynamic timehistory simulations were performed at different seismic intensity increments. This research aims to promote the use and development of fragility curves as an alternative to ensuring the safety of those who use buildings or similar structures.
