Investigation of the effect of cladding element and insulation material on lateral load resistance of shear walls
Abstract
Shear walls in lightweight carcass timber construction systems; The skeleton system, in which solid material is generally used, consists of covering or covering elements and fasteners. As a covering element, plywood is used because it resists the horizontal deformation of the structure, such as earthquake and wind, and prevents it from collapsing. There are many factors that affect the structural properties of the curtain wall and the technological properties of plywood. Factors such as wood type, board thicknesses, fiber direction, defects, type of fasteners, location and distances between them are effective on the durability, strength and amount of horizontal deformation of the shear wall. The combination of these factors determines the overall performance of the shear wall and the amount of horizontal deformation. In this study, it was aimed to determine the amount of horizontal deformation in shear walls under lateral load. The study examines the impact of structural and technological factors on plywood shear walls made of black pine and spruce wood species. The research evaluates a number of variables such as wood type (black pine and spruce), plywood board thicknesses, fiber orientation (perpendicular and parallel to the fibers), imperfections, fastener size (6d and 8d). Insulation materials used in shear walls (such as Extruded Polystyrene (XPS), Expanded Polystyrene (EPS)) were also taken into consideration and the amount of horizontal deformation under lateral load was. The results of the research showed that shear walls covered with black pine plywood generally undergo more horizontal deformation than spruce, and shear walls produced in parallel with the fibers generally have higher horizontal deformation values.
