STRUCTURAL RESPONSE AND DAMAGE EVALUATION OF A TYPICAL HIGHRISE RC BUILDING IN DUBAI UNDER AN EARTHQUAKE WITH SINGLE AND MULTIPLE PEAKS

Seismic design codes predominantly assume that earthquakes involve a single ground shaking event; however, can occur as series of shocks. Consequently, the capacity structures to resist with multiple peaks without suffering severe damage is crucial parameter. This research study evaluates seismic performance high-rise building in Dubai using existing records and peaks. Three-dimensional model was developed considering actual cross-sections horizontal vertical elements fitting zone through dynamic response spectrum analysis. The analyzed nonlinear regime employing fast-nonlinear timehistory analysis scaled NS EW Niigata earthquake. main finding this work significantly increase structural magnify compared single-peak earthquakes; thus, involving shocks risk failure building.
