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 blocks, one each affixed to a top and bottom flange of a beam. Each buckling restraint block includes one or more bores formed through a center of the block. The lateral bracing system further includes at least one yield link for each buckling restraint block. Each yield link includes a first end affixed to the column, and a second end fit through a bore in a buckling restraint block and affixed to an end of the buckling restraint block.
Claims18
A construction including a beam and a column, the construction comprising:
- a buckling restraint block capable of being affixed to an end of the beam, the buckling restraint block including a first end nearest the end of the beam when the block is affixed to the beam, a second end opposite the first end and a bore between the first and second ends;
- and
- a yield link including a first end capable of being affixed to the column, and a second end fit through the bore in the buckling restraint block and capable of being affixed to the second end of the buckling restraint block, the yield link having a length over which forces act to allow the yield link to yield in tension and compression to dissipate stress within the frame upon a lateral load applied to the beam and/or column, and wherein the yield link includes a middle section having a lower strength than the first and second ends, the yield link yielding at the middle section upon a given tensile force.
A construction, comprising:
- a column;
- a beam;
- a shear tab affixed between the column and beam;
- and
- a lateral bracing system affixed between the column and beam, including:
- a pair of buckling restraint blocks, one each on a top and bottom flange of the beam, each buckling restraint block including a first end affixed to an end of the beam, a second end opposite the first end and at least one bore between the first and second ends;
- and
- a pair of yield links, each yield link including a first end affixed to the column, and a second end fit through the bore in one of the buckling restraint blocks and affixed to the second end of one of the buckling restraint blocks, a yield link of the pair of yield links provided for a purpose of yielding in tension and compression to dissipate stress within the frame upon a lateral load applied to the beam and/or column, and wherein each yield link includes a middle section having a smaller diameter than the first and second ends.
A construction including a beam and a column, the construction comprising:
- a buckling restraint block affixable to an end of the beam, the buckling restraint block including a first end nearest the end of the beam when the block is affixed to the beam, a second end opposite the first end and a cylindrical bore between the first and second ends;
- and
- a cylindrical yield link extending through the bore and including a first end affixable to the column, and a second end affixable to the second end of the buckling restraint block, the yield link capable of yielding in tension and compression to dissipate stress within the frame upon a lateral load applied to the beam and/or column, and wherein the yield link includes a middle section having a lower strength than the first and second ends, the yield link yielding at the middle section upon a given tensile force.
