Keywords: concrete, nonlinear static analysis, reinforced concrete buildings, seismic vulnerability, structural shear wall
Swiss Federal Institute of Technology developed a simple method to evaluate seismic vulnerability of reinforced concrete buildings with structural walls using an engineering approach. The objective of this research was the evaluation of the developed method through the capacity curve with a focus on the buildings with frame action due to the coupling of the walls by piers and spandrels. For this purpose, a numerical model of a six-story reinforced concrete structure with sixteen structural walls was created in two directions and nonlinear static analysis was performed to obtain the capacity curve under different lateral load patterns. It was found that there is an appropriate overlap between the numerical model and developed method in terms of capacity curve and vulnerability.
