Past and current seismic design provisions for steel structures in Japan are presented and compared with Canadian requirements. The performance of steel framed structures during the January 17, 1995, Hyogo-ken Nanbu earthquake is described. Numerous failures and examples of inadequate behaviour could be observed in buildings of various ages, sizes, and heights, and braced with different structural systems. In moment resisting frames, the damage included failures of beams, columns, beam-to-column connections, and column bases. Fracture of bracing members or their connections was found in concentrically braced frames. The adequacy of the current Canadian seismic design provisions is examined in view of the observations made. Key words: earthquake, seismic design, steel structures.

The Impact

New provisions of the CSA standard for steel structures (CAN/CSA-S16.1-M89) dealing with detailing of concentrically braced frames for seismic design are described and related to requirements of the National Building Code of Canada. The basis of the new requirements is outlined, and an example eight-storey frame is used to outline a methodology for the design process for a ductile braced frame and to illustrate the impact of the provisions. Key words: design, structural engineering, steel, earthquakes, braced frame, standards.

Steel Braced Frame

Extensive research into the inelastic seismic response of concentrically braced frames and their components has been carried out in the last two decades. This knowledge has now been incorporated into seismic design practice in several countries, notably the U.S.A., Canada, and New Zealand. In this paper, design specifications from these three countries, which derive largely from the same body of research, are compared. The basic design philosophy for concentrically braced steel frames, loading, and member detailing are examined. It is concluded that, in general, the Canadian specifications are in conformity with the available information and have many similar features to codes of the other countries. Significant differences exist in the classification of braced frames, between interstorey drift requirements, in the treatment of dual structural systems, and to a lesser extent in member detailing requirements. Some features of Canadian codes meriting review are identified. Key words: structural engineering, earthquakes, standards, steel, braced frame, ductility, concentric bracing, dual system.

Concentrically Braced Frames (CBFs) are among the most commonly used lateral resisting systems utilized in the construction of steel structures due to their rigidity, low lateral displacement and ease of implementation. However, the lack of ductility due to the buckling that occurs in the bracing elements before yielding is their main disadvantage. This study presents an innovative Composite Buckling Restrained Fuse (CBRF) to be used as a bracing segment in concentrically braced frames that improves the ductility and eliminates premature buckling. The proposed CBRF with relatively small dimensions is a hysteretic damper consisting of thin steel plate core and extra tensile elements embedded in a composite encasement. Two CBRF samples are designed and tested experimentally. The results indicate that the proposed structural fuse has a ductile behaviour with high energy absorption and sufficient strength along with a reasonably stable hysteretic response under cyclic load.
