influence of infill walls on resilience index of rc schools using the bim analysis and fema p-58 methodology

In this study, general method of evaluation based on resilience has been investigated using pact software and available mathematical functions. in this regard, in accordance with standard no. 6 and 9 of national building regulations (nbr) and iranian code of practice for seismic resistant design of buildings, a school with intermediate concrete moment frames and shear walls has been designed. the school was modeled in the revit software with two different levels of detail (lod) of 300 and 350. the difference between these two levels is the accuracy of infill walls modeling. then, using etabs software, nonlinear dynamical analysis (nonlinear time history analysis) for frames was performed considering the impact of near-field and far-field earthquakes to obtain the fragility curves. after that, the fragility curves were calculated for all structural and non-structural components related to different damage levels in fema code and eventually, resilience values were obtained. in fact, the results of etabs software were entered as input into pact software and the outputs such as damage median, recovery time and etc. were used to determine the resistance. the results show that reducing the seismic responses of building in lod350 model leads to a 184-days reduction in recovery and 12% increase in resilience, which indicates the importance of detailed modelling in earthquake damage evaluation. the values of recovery times for buildings with lod300 and lod350 have been obtained as 352 and 167 days, respectively, while normalized curves of damage cumulative distribution shows that median costs of repair for lod300 and lod350 buildings were 22 and 10%, respectively. the comparison between maintenance cost curves demonstrates that the median cost of damage in lod350 building is about 12% less than lod300 building.
