Shear wall, a continuous vertical member, is an important element in high-rise building,rnwhich provides the lateral stability and resistance to lateral force. Lateral load resistancerncapacity of shear wall is controlled by two parameters, the strength and the ductility; it isrnbetter to have the shear strength somewhat greater than the compressional to prevent shearrnfailure, which is brittle, sudden and of serious consequence. Due to the architectural andrnfunctionality reasons, openings are providing in this important structural part.rnThe main objective of this study is to investigate the effects of shear deformation on shearrnwall with different type of openings and wall dimension for later action using simplifiedrnhand procedure. To investigate the effect of shear deformation, parametric study presentsrnfor shear wall deformation. A total of thirty-two cases of systematically random selectedrninput variables namely: height of shear wall (H), length wall (L), opening height (ho),rnopening length (lo) and thickness for shear wall with window and door type of opening.rnFor solid shear wall (without opening) input variables are height of wall (H) length of wallrn(L) and thickness (t). The systematically selection random variables is done using LatinrnHypercube Sampling method (LHS). Those random variables distribution follow normalrndistribution. And then by taking the shear deformation of thirty-two cases of shear wallrnwith and without opening from simplified hand procedure, verified by illustrative examplernand ANSYS, a statistical data analysis is performed using regression analysis in order tornidentify the most influential input parameter on the shear wall deformation of shear wall.rnResults of statistical data analysis demonstrates the significance of five input variables onrntwo cases, shear wall with and without opening and three input variables on solid shearrnwall. Height of opening most influential parameter for shear wall with and withoutrnopening. But for shear wall without opening thickness of wall is influential parameter forrnthe determination of shear deformation. On other hand, this paper provides some supportrnto identify which parameter increase and which parameter decrease shear deformation tornreduce brittle failure in of shear wall. This will enable to consider factor of safety forrnthe uncertain input parameters on shear deformation equations. It is helpful to constructrnempirical equation using large set of data.
