  • Envelope-based pushover analysis procedure for assessing the collapse risk of buildings [Elektronski vir]
    Brozovič, Marko ; Dolšek, Matjaž
    The pushover-based procedure for assessing the collapse risk of taller buildings is proposed. The procedure utilizes recently introduced Envelope-based Pushover Analysis (EPA), which involves ... so-called modal-based and failure-based SDOF models corresponding to three pushover analyses. The EPA procedure is used to determine the collapse fragility, whereas the assessment of collapse risk is based on the well-known closed-form solution of the risk equation. The procedure is demonstrated by means of an example of a 15-storey reinforced concrete frame building taking into account two hazard-consistent sets of ground motions. It is shown that the EPA procedure provided sufficiently accurate estimates of collapse risk in comparison to that based on the nonlinear response history analysis. The basic pushover method, which is not capable of simulating different system failure modes due to the effects of ground motions, failed to predict the collapse risk with a useful degree of accuracy.
