Lateral motion devices are used in conjunction with shear assemblies to
further dissipate shear forces on buildings. In one embodiment, the
lateral motion device is interposed between the shear assembly and the
upper portion of the wall to permit relative motion therebetween and to
absorb and dissipate a portion of the shear forces through expansion
and/or compression of spring members. In another embodiment, the lateral
motion device is interposed between the foundation and the bottom of the
shear assembly and in yet another embodiment, the lateral motion device
is embedded in the foundation so as to be interposed between the anchor
bolt and the foundation. The shear assembly can be either a panel
assembly or an A-frame assembly.
