Structural reliability of the San Ignacio medical facility, when affected by seismic excitation

Federico Núñez, Edgar Muñoz, Jorge Prieto

Abstract


Is work deals with the physic seismic vulnerability of the B module of the San Ignacio medical facility using the structural reliability technique. This studywas based on a dynamic spectral model of the building, by varying actions (moment, shear and axial force) generated in the model and resorting to thirty(30) response spectra with different return period. It also resorted to the study of the pathology of materials, in which destructive and non-destructive assayswere conducted to study the resistance variation of the main structural elements that are part of the structure (columns, beams, capitols). By comparing theactions and resistance curves, probable failure indexes where evaluated and different local and global failures where evaluated in the face of a seismicevent. These results are similar to those obtained in a study (Amezquita, et al 2002) developed by the Civil Engineering Department of the PontificiaUniversidad Javeriana, indicating a problematic situation in the structure.
