Abstract

A shear wall is a vertical member with a relatively large volume that is used frequently as a vertical passage and a lateral load support system in every building without exception. Many studies have been conducted on the sustainable design of buildings, but few have studied the sustainable design of shear walls considering CO ₂ emissions. Herein, a sustainable design model for shear walls is developed to analyze the relationship between building height, CO ₂ emissions, and construction cost. The model is applied to the sustainable design of shear walls installed in a 42-story mixed-use building. The characteristics in the change in CO ₂ emissions and the construction cost according to the building height were analyzed using the slenderness ratio as a variable. The results indicated that as the slenderness ratio increased, the CO ₂ emissions increased almost linearly in proportion to the height. In particular, when the slenderness ratio increased from 4.40 to 4.93, which is known to be the limit of the efficient applicability of shear walls, the CO ₂ emissions tended to increase more rapidly. When the slenderness ratio was 4.93, the CO ₂ emissions for the shear wall were reduced to 27.24% by the proposed model.
