STEEL FRAME STRESS REDUCTION CONNECTION

摘要

The present invention provides for improvement of strength performance of connections in structural steel buildings made typically with rolled structural shapes, specifically in beam-to-column (306) connections made with bolt or riveted weld web connections and welded flanges, to greatly reduce the very significant uneven stress distribution found in the conventionally-designed connection at the column/beam weld, through use of slots in column (130) and/or beam webs (136) with or without continuity plates (106) in the area of the column between the column flanges, as well as, optionally extended shear connections (48) with additional columns of bolts for the purpose of reducing the stress concentration factor in the center of the flange welds.
