Coupling beams of coupled shear wall systems are often the most critical members in medium or high rise buildings subject to seismic load or wind loads. To ensure the survival of shear walls under high-intensity cyclic loading, these beams, which normally have limited dimensions, should possess high deformability and good energy absorption while being able to resist large shear force. Experimental work are conducted to illustrate the design of special RC coupling beams using the proposed procedure reinforcement details.
