Energy dissipating assembly for frame walls
Abstract:
Lateral motion devices are used in conjunction with relatively rigid shear assemblies to further dissipate shear forces on frame construction 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 energy associated with shear force through spring-like behavior and deformation. In one embodiment, the energy dissipation is achieved by a plurality of corrugation structures, where the top of the corrugation is attached to the upper portion of the wall and the bottom of the corrugation is attached to an interconnecting assembly that is securely attached to the foundation. Placing the energy dissipating device near the upper portion of the wall mounted on a comparatively rigid frame provides a relatively short moment arm with respect to the lateral forces imposed by the wall on the energy dissipating device to allow better control of the response to the shear force.
