CANADIAN REQUIREMENTS FOR SEISMIC DESIGN OF DUCTILE STEEL STRUCTURES

摘要

The Canadian Standards Association formally approved CSA Standard S16-01 in October of 2001. This newest Canadian standard for the limit states design of steel structures continues to provide seismic requirements in its Clause 27. However, due to the significant amount of new information from research, such as the SAC project, the work in Canada on steel plate shear walls, bracing systems and connections, and that from other sources, Clause 27 underwent a complete overhaul. The basis of the new seismic requirements is capacity design principles. Clause 27 provides design and detailing requirements for eight lateral load-resisting systems over a broad range of ductile performance expectations. This paper provides an overview of these new seismic design requirements.
