Abstract: A moveable structural reinforcement system is described including a moveable panel adapted to substantially close a building opening, the panel including variable shear load resistance means for regulating the shear stiffness of the building when the panel is in a closed position.

Abstract: A moveable structural reinforcement system is described including a moveable panel, a metal frame structure connectable to the frame structure of a building opening, the frame structure including a top support member and lateral supports connected on a first end to the top support member, upper load members disposed on the top support member proximate the lateral supports, bottom load members disposed on the second ends of the lateral supports, and load transfer members disposed substantially diagonally on said panel and adapted to releasably engage the upper and lower load members. The load transfer members providing a substantially continuous load path when the panel is in a closed position and the building or structure is subjected to a lateral force.

Abstract: A structural connection system for resisting uplift loads on the shear walls for each level of a wood frames structure includes anchors for each level. The system, employed at least at the lateral ends of the shear walls, compressively restrains the shear walls against upward movement. The anchors, which are vertically aligned, are coupled to one another through tie rods. A tie rod connects the anchor for the bottom floor to a foundation anchor embedded in the foundation. The anchors and tie rods are positioned between pairs of closely spaced vertical framing elements, such as studs. Uplift loads for each level are transferred to the foundation through the connection system. This eliminates any accumulation of uplift loads from level to level.
