Abstract
A prefabricated shearwall including a central diaphragm having a height generally defined by top and bottom edges, and a width generally defined by a pair of end sections. The diaphragm further includes at least one corrugation extending in the height direction at least partially between the top and bottom edges. The corrugation increases the ductility and ability of the shearwall to withstand lateral forces such as those generated in earthquakes, high winds, floods and snow loads.
Claims16
A shearwall construction, comprising:
- a shearwall, comprising:
- a central diaphragm, including:
- a top edge and a bottom edge generally defining a height of said central diaphragm,
- first and second ends, extending between the top and bottom edges, generally defining a width of said central diaphragm, the first and second ends further defining a depth of the central diaphragm perpendicular to the height and width of the central diaphragm, the first and second ends oriented parallel to each other to provide a rectangular footprint of the central diaphragm;
- a corrugated section extending between said top edge and said bottom edge, attached to and extending from said first and second ends, said corrugated section forming at least one corrugation having holes therein;
- a pair of wooden chords including a first wooden chord affixed to the first end and a second wooden chord affixed to the second end, the chords extending along the height and depth of the central diaphragm;
- and
- a bottom plate mounted at the bottom edge of the central diaphragm, the bottom plate extending along the depth of the central diaphragm and the width of the central diaphragm plus the pair of chords, support of the pair of chords on the bottom plate preventing moisture entering the pair of chords from a surface on which the shearwall is supported, the bottom plate including a pair of holes for receiving anchors;
- a concrete foundation as the surface on which the shearwall is supported;
- and
- a pair of anchors fit through the holes in the bottom plate anchoring the shearwall to the concrete foundation.
