Abstract: Shear walls are popular structural systems to resist lateral forces acting on building such as wind and earthquake. structural engineers are interested in the accuracy of computational models for shear walls because for dynamic loading, the absolute stiffness of shear wall systems is the prime determinant for the design base shear of the building. In this research, was studied the effect of making different openings at shear walls to investigate the effectiveness of opening on the stiffness and strength of the reinforced wall, The experimental program consisted of four reinforced concrete walls with different openings supposed to lateral load. The results show that, Usage two vertical openings at center is better than use one central opening has A bad effect on stiffness of wall.it is recommended for the architectural usage. Key Words —shear walls with openings, stiffness of wall, lateral load Al-Azhar University Civil Engineering Research Magazine (CERM) Vol. (43 ) No. ( 2 ) April . 2021
