Closing the Guidance Gaps on Coupling Beams Used in Core Wall Systems Subjected to Wind Events
When the beam shear demands in coupled core wall systems, commonly used in mid- to high-rise towers, become relatively large, the typical reinforced concrete beam is no longer adequate. It is common, in these cases, to either use a concrete-encased structural steel coupling beam or simply a steel coupling beam. The current requirements for the analysis, design, and detailing for steel and concrete encased steel coupling beams provide for high seismic applications, however, fall short in regard to applications for wind events. The driver for this research is to close the guidance gaps.
