Seismic Force Demand on Brace Connections of Conventional Construction Braced Steel Frames Designed According to Canadian Seismic Provisions
This paper presents the results of an ongoing research project on the seismic performance of concentrically braced steel frames of the Conventional Construction category designed according to NBCC 2005 and CSA-S16 seismic provisions. These structures are expected to remain essentially elastic during strong ground motions. Linear time history analyses were performed on typical braced steel frames of this category to assess the force demand on brace connections. Different building heights were considered. The structures were assumed to be located in both eastern and western Canada to reflect two different seismic conditions. Two local soil conditions were also examined: site classes C and E. The computed force demand varied with the building height, the location and the site class. In several cases, it exceeded the predictions from multi-modal response spectrum analysis, which is mainly attributed to the assumptions made on damping and higher mode response. Recommendations on design forces are given to prevent brittle failure of brace connections.
