  • Patent number: 8082703
    Abstract: A force resisting device for transmitting forces and dissipating and absorbing energy in a shear wall or shear wall segment includes at least one active element, the active element having a force versus deflection property under at least one cyclic load such that the shear wall has at least one building code compliant parameter. The building code compliant parameter includes an equivalent response coefficient, R, a system overstrength coefficient, W, and a deflection amplification factor, C. Exemplary embodiments of prefabricated shear walls or shear wall segments include the disclosed force resisting device. Exemplary embodiments of buildings include the disclosed prefabricated shear wall or shear wall segment with the disclosed force resisting device.
