Experiment Study on Ductility of Composite Shear Walls

전단벽의 연성도에 대한 단부보강 H형강 철물의 효과

Composite boundary elements with H steel sections could be used to enhance the strength and ductility of high-rise shear walls. The enhancement of earthquake resistance is expected to be achieved due to the inherent strength and ductility of the steel sections, and also due to the confinement effect to a core concrete. Experimental study were peformed for the compression zone of composite shear walls with multiple H sections at the boundaries. The effect of the steel sections on the overall behavior of the composite shear walls were investigated. Also, additional tests were conducted to investigate the contribution of H sections to the confinement of concrete.
