EXPERIMENTAL STUDY AND NUMERICAL ANALYSIS ON EFFECT OF OPENING WITH DIFFERENT ASPECT RATIO IN SQUAT WAL

Abstract

The primary focus of this work is to investigate, both experimentally and statistically, the impact of window openings with various aspect ratios on the in-plane shear capacity of RCCsquat walls. For this purpose, three scaled models of squat walls with identically sized openings but various aspect ratios in each wall have been cast. Used openings had B/H ratios of 1/2, 1, and 2/1. 10% of the wall's area was opening. The same loading rate was used for monotonic loading on all three samples. In-plane force and horizontal displacement served as experimental measurements. The largest in-plane sharing capacity is found for walls with opening aspect ratios of B/H=1/2, while the lowest capacity is found for walls with opening aspect ratios of B/H=2/1. To quantitatively validate our experimental results, a numerical model was created using ABAQUS Software as a FEM program. The finite element simulation was performed using the recommended modeling methodologies, and the validity of the numerical model was assessed by comparing the results to those of the experiments. This numerical solution was discovered to be quite close to experimental findings. This research now offers a solid foundation for choosing the opening aspect ratio for squat walls that are already built or freshly developed.
