    摘要： The present invention provides for improvement of ductility and strength performance of connections in structural steel buildings made typically with rolled structural shapes, specifically in bolted and/or welded beam-to-column connections with welded flanges, by greatly reducing the very significant uneven stress distribution found in the conventionally designed connection at the column/beam weld, through use of slots in column and/or beam webs with or without continuity plates in the area of the column between the column flanges, as well as, optionally, extended shear plate connections with additional columns of bolts for the purpose of reducing the stress concentration factor in the center of the flange welds. Moreover, the slots in beam web adjacent to the beam flanges allow the beam web and flange to buckle independently thereby eliminating the degrading of the beam strength caused by lateral-torsional bucking.

    摘要： Embodiments of the present invention relate to a structural frame member which includes a brace member that is used to absorb energy when the structural frame is subjected to loadings such as seismic, wind and gravity loads. The brace member is coupled to a restraining member that increases the buckling capacity of the brace member so that the brace member has approximately the same load axial capacity in compression as in tension. Embodiments of the invention also relate to the design, construction and assembly of the connection of the brace member that couples the brace member to a gusset plate which is coupled to the beam and column in the structural frame.
