Combined effect of removing corner columns and vertical openings in an L-shaped shear wall

Abstract

This study examines several buildings braced with L-shaped shear walls, with and without corner columns. In this case, the L-shaped shear wall consists of two walls, each with vertical rectangular openings. At the same time, three wall thicknesses 15cm, 20 cm, and 25 cm were used in buildings of 4, 7, and 11 stories. A comparison was made between walls with and without columns based on tensile stresses and dynamic shear forces at the base of the buildings. The maximum displacements at the tops of the buildings were also compared between those braced with shear walls with and without corner columns. The results show that the analyzed parameters for the L-shaped shear walls, following the removal of the column, were strongly influenced by both the number of stories and the percentage of openings in the wall. Permissible openings in L-shaped walls without corner columns will be proposed based on the three wall thicknesses and the number of stories examined.
