Abstract
A shearwall is disclosed for use in lightweight or other constructions to transmit lateral shear forces and dissipate energy on the construction. In examples, the shearwall includes a central panel formed of wood, and side plates formed of steel. The side plates may be affixed at lower corners of first and second opposed surfaces of the central panel. Each side plate may include a fastening plate for affixing the side plate to the central panel, and a restraint plate which fits within a reduced area section of the central panel between the first and second surfaces.
Claims21
A shearwall for use in constructions, the shearwall comprising:
- a central panel comprising first and second surfaces and a section having a reduced area between the first and second surfaces;
- a plurality of side plates configured to be connected to the central panel at lower corners of the first and second surfaces, the side plates further configured to be coupled to a support surface on which the shearwall is mounted, the plurality of side plates comprising restraint plates, the restraint plates positioned within the section of the central panel having a reduced area and the restraint plates configured to inhibit buckling of the central panel after initial buckling of the central panel.
A shearwall for use in constructions, the shearwall comprising:
- a central panel comprising first and second surfaces, and a section having a reduced thickness between the first and second surfaces;
- a plurality of side plates comprising:
- fastening plates for fastening the side plates to the central panel, and
- restraint plates on the fastening plates, the restraint plates of first and second side plates fitting within the section of the central panel having a reduced area;
- wherein the section in the central panel of reduced area provides a predictable location of yielding of the shearwall;
- and
- wherein the restraint plates provide ductility after initial yielding of the shear wall by opposing yielding of the central panel after initial yielding of the shearwall.
A shearwall for use in constructions, the shearwall comprising:
- a central panel comprising first and second surfaces and sections having a reduced area between the first and second surfaces;
- a plurality of side plates configured to be connected to the central panel at lower corners of the first and second surfaces, the side plates further configured to be coupled to a support surface on which the shearwall is mounted, the plurality of side plates comprising restraint plates, the restraint plates positioned within the sections of the central panel having a reduced area and the restraint plates configured to transfer loads on the central panel to the support surface.
