SpeedCore systems or concrete-filled composite plate walls have been recently developed as a new lateral force-resisting system for mid- and high-rise buildings. These core walls have been recently adopted in ASCE/SEI 7-22. For coupled configurations, the highest response modification coefficient (R) of 8.0, an over-strength factor (Ω0) of 2.5, and a deflection amplification factor (Cd) of 5.5 have been specified in ASCE 7-22. A SpeedCore system offers the main advantage of substantially reducing construction time and notably improving the overall economic viability of construction projects. The Rainier Square Tower and the 200 Park Avenue projects are the first system implementations in the world. However, the National Building Code of Canada (NBC) and the Standard for the Design and Construction of Steel Structures (CSA S16) have not yet adopted the system.

摘要

SpeedCore systems or concrete-filled composite plate walls have been recently developed as a new lateral force-resisting system for mid- and high-rise buildings. These core walls have been recently adopted in ASCE/SEI 7-22. For coupled configurations, the highest response modification coefficient (R) of 8.0, an over-strength factor (Ω0) of 2.5, and a deflection amplification factor (Cd) of 5.5 have been specified in ASCE 7-22. A SpeedCore system offers the main advantage of substantially reducing construction time and notably improving the overall economic viability of construction projects. The Rainier Square Tower and the 200 Park Avenue projects are the first system implementations in the world. However, the National Building Code of Canada (NBC) and the Standard for the Design and Construction of Steel Structures (CSA S16) have not yet adopted the system. This paper reviews the development, past research, and implementation of SpeedCore systems. Then, the design requirements of the system for Canada, as well as a detailed analysis and design methodology, are presented for use in Canada. An example archetype wall is analyzed and designed according to the proposed methodology.
