Abstract: A method of construction of composite wall module system in which a first wall module and a second wall module are coupled to the first wall module by a vertical joint. The vertical joint is comprised of plurality of anchors and reinforcement bars as well as steel side plates allowing composite wall steel faceplates to be discontinuous across the vertical joint. The faceplates of the first and second modules are not made continuous across the vertical joint through continuous welding. The vertical wall joint further includes fill disposed between faceplates and side plates adjacent to anchors and reinforcement bars.

Abstract: A damper system for installation in a structure to dissipate seismic and wind energy transmitted to the structure, includes first and second pairs of elongated members forming an outer parallelogram, third and fourth pairs of elongated members forming an inner parallelogram, and a pair of energy dissipating devices connected between the parallelograms for dissipating the energy transmitted to the structure.

Abstract: A multi-floor building is protected from seismic forces by coupling a damping system between a pair of truss columns of truss systems, each movable in a cantilever motion in response to the seismic forces to move opposite nodes of the damping system along an enhanced working stroke as compared to prior art frame constructions.
