Displacement of Reinforced Concrete Space Shear Walls as a Result Of Earthquake Effect

Abstract

In reinforced concrete buildings, gaps are formed in certain parts of the curtains. There are displacements in reinforced concrete shears under the effect that simulates an earthquake. Accordingly, in this study, the change between force-displacement relations was examined. The curtains that are the subject of the study are slender curtains with a height/height (Hw/ℓw) ratio higher than 2.5-3.0 according to TBDY 2018, and slender curtains with a combined shear-bending behavior with aspect ratios between two limits. are given as medium-delicate curtains. The effect on the behavior according to the void ratios left at the midpoint of the reinforced concrete curtains was investigated. For this, a total of 4 pieces with ½ scale; Reinforced concrete shears, one of which is a reference and the others with a void ratio of 20%, 35% and 50%, respectively, were produced and the results were compared under the effect of earthquakes. The size effect was tried to be avoided, but since the actual dimensions of the sample were too large, it was produced in 1/2 scale. In the study, a built-in support condition should be created in the laboratory environment in order to represent the curtains structurally close to the real behavior.
