Seismic performance of ductile medium height reinforced concrete frame buildings designed in accordance with the provisions of the 1995 National Building Code of Canada

This paper describes an investigation into the seismic performance of a six -storey ductile moment-resisting frame structure located in Vancouver and d esigned and detailed in accordance with the seismic provisions of the Natio nal Building Code of Canada (1995). Both pushover and dynamic analyses are conducted using an inelastic model of the structure as designed and detaile d. The structural performance of a number of design variations is evaluated using interstorey drift and member curvature ductility response as perform ance measures. All frames studied are expected to perform at an operational level when subjected to design level seismic excitations and to meet life safe performance criteria at excitations of twice the design level.
