Abstract

A lateral bracing system is disclosed for affixing a column to a beam in a construction. The lateral bracing system includes a pair of buckling restraint plates, one each affixed to a top and bottom flange of a beam. The lateral bracing system further includes at least one yield plate for each buckling restraint plate. Each yield plate includes a first end affixed to the column, and a second end affixed to the beam.

Description

PRIORITY DATA

[0001] This application is a continuation-in-part application of U.S. patent application Ser. No. 11 / 959,696 entitled “MOMENT FRAME CONNECTOR,” filed Dec. 19, 2007, which application claims priority to U.S. Provisional Patent Application No. 60 / 871,587, entitled “Moment Frame Connector”, filed Dec. 22, 2006. Both applications are incorporated herein by reference in their entirety.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to hysteretic damping for structures used in light-framed constructions, and in particular to a lateral bracing system constructed to provide a high degree of energy dissipation through hysteretic damping along with high initial stiffness so that energy is dissipated at low force thresholds within a light-framed construction.

[0004] 2. Description of the Related Art

[0005] Shear stresses due to natural phenomena such as seismic activity and high winds can have devastating effects on the structural integrity...
