(05.08.2017) SPO2FRAG V1.1 (beta) RELEASED: SPO2FRAG software is an interactive tool that can be used for approximate, computer-aided calculation of building seismic fragility functions, based on static pushover analysis. At the core of the SPO2FRAG tool lies the SPO2IDA algorithm, which permits analytical predictions for incremental dynamic analysis summary fractiles at the SDOF level. By effectively interfacing SPO2IDA with a series of operations, intended to link the results of static pushover analysis with the variability that typically characterizes non-linear dynamic structural response, SPO2FRAG provides an expedient solution to the computationally demanding task of analytically evaluating seismic fragility. Input for SPO2FRAG is simply the push-over curve for the structure of interest, while the output consists of fragilities for arbitrarily-defined limit states. SPO2FRAG revolves around a graphical user interface (GUI) that allows the user immediate visualization of all intermediate and final results.
