Seismic design of multi-tiered steel braced frames including the contribution from gravity columns. Imanpour, A., Auger, K., & Tremblay, R. In volume 106, 2014. Braced frame;Lateral resistance;Response history analysis;Seismic behaviour;Seismic demands;Seismic loadings;Seismic Performance;Steel braced frames;abstract bibtex The influence of engaging gravity columns to resist the in-plane flexural demand imposed on the columns of multi-tiered steel braced frames subjected to seismic loading is investigated. Various approaches are proposed for the design of the braced frame and gravity columns of a four-tiered prototype steel braced frame. The seismic behaviour of the frame is examined using the nonlinear incremental static and response history analysis methods. The results of the analyses show that the gravity columns can effectively contribute to reducing the in-plane flexural demand on the braced frame columns. Enhanced braced frame seismic performance is also expected as nonlinear seismic demand on the bracing members is also reduced when mobilizing the gravity columns for lateral resistance.
