Abstract:
A shear frame assembly of the type having a pair of tensioned diagonal straps that provide resistance to shear loads. The shear frame assembly includes a pair of laterally opposed vertical supports each having a first end portion and each vertical support has an aperture in its first end portion. The aperture is sized to receive one of the tensioned diagonal straps therethrough. Transverse top and bottom plates extend between the end portions of the vertical supports. A strap-alignment member is positioned in each aperture and each alignment member is positioned to receive and align the tensioned strap within the aperture. A force distributing member is positioned in each aperture and interposed between the alignment member and the respective vertical support. Each vertical support is formed by three studs that are connected together by bands that wrap around the studs so as to sandwich the middle stud between inner and outer studs. A building system for constructing a building using the shear frame assemblies includes a plurality of building wall frame assemblies and shear brace assemblies that are interconnected to each other in a configuration that forms the selective walls of the building.
