FRAGILITY ANALYSIS OF CODE DESIGNED IMF CONCRETE BUILDINGS IN ENCOUNTERING DIFFERENT HAZARD LEVELS

Global collapse in earthquake engineering refers to the inability of a structural system to sustain gravity loads when subjected to seismic excitation , global collapse phenomena in existing buildings is a main concern and therefore strictly criteria based on DCR ratio in seismic evaluation standards and guideline manual presented for avoiding this phenomena.
