Probabilistic assessment of SMRFs with infill masonry walls incorporating nonlinear soil-structure interaction

Abstract Infill Masonry Walls (IMWs) are used in the perimeter of a building to separate inner and outer space. IMWs may affect lateral behavior buildings, while they different from those partition walls that two spaces. This study focused on seismic vulnerability assessment Steel Moment-Resisting Frames (SMRFs) assuming placement incorporating nonlinear Soil-Structure Interaction (SSI). The aim is explore damage states use their ability for improving SMRFs. For this purpose, three, five, seven, nine story levels (3-Story, 5-Story, 7-Story, 9-Story) SMRFs were modeled considering four soil types. Incremental Dynamic Analyses (IDAs) performed determine performance limit-state capacities Far-Fault (FF) record subset suggested by FEMA P695. To accurately model influence response SMRFs, Tcl programming algorithm was developed intelligently monitor each floor level. Results analysis show can significantly increase with without SSI effects. In addition, play crucial role improve performances as well collapse probability, which be retrofitting purposes.
