Moment frame for a sloped roof construction

A sloped roof construction, comprising:

• a vertical column comprising:
• a top edge at a non-horizontal angle following a slope of the roof, and
• a connecting face adjacent the top edge;
• a beam having a major axis at the non-horizontal angle, a first flange following the slope of the roof and a second flange;
• a shear tab affixed between the column and beam, between a top and bottom flange of the beam;
• and
• a lateral bracing system affixed between the column and beam, including:
• first and second buckling-restrained braced devices, one each on the top and bottom flange of the beam, the first buckling-restrained braced device comprising:
• a first yield link comprising:
• a first end comprising a first planar section with a first surface configured to mount parallel to and against the top edge of the column,
• a second end comprising a second planar section with a second surface configured to mount parallel to and against the first flange of the beam, and
• a section of narrowed width between the first and second ends, the narrowed width section defining first and second notches on opposite sides of the first yield link, the first yield link configured to yield in tension and compression at the narrowed width section to dissipate stress within the construction upon a lateral load applied to one or more of the beam and column;
• first and second spacers fitting within the first and second notches, respectively;
• and
• a buckling restraint plate configured to mount over the first yield link and spacers to sandwich the first yield link and spacers between the buckling restraint plate and the first flange of the beam.

A sloped roof construction, comprising:

• a vertical column comprising:
• a top edge at a non-horizontal angle following a slope of the roof, and
• a connecting face adjacent the top edge, the connecting face provided at a non-vertical angle perpendicular to the slope of the roof;
• a beam having first and second flanges and a major axis at the non-horizontal angle following the slope of the roof;
• and
• a lateral bracing system affixed between the column and beam, including:
• first and second buckling-restrained braced devices, one each on a top flange and a bottom flange of the beam, the first buckling-restrained braced device comprising:
• a first yield link comprising:
• a first end comprising a first planar section with a first surface configured to mount parallel to and against the top edge of the column,
• a second end comprising a second planar section with a second surface configured to mount parallel to and against the first flange of the beam, and
• a first section of narrowed width between the first and second ends, the first narrowed width section defining first and second notches on opposite sides of the first yield link, the first yield link configured to yield in tension and compression at the first narrowed width section to dissipate stress within the construction upon a lateral load applied to one or more of the beam and column;
• and
• a first buckling restraint plate configured to mount over the first yield link to sandwich the first yield link between the buckling restraint plate and the first flange of the beam;
• the second buckling-restrained braced device comprising:
• a second yield link comprising:
• a first end comprising a perpendicular plate configured to mount parallel to and against the connecting face of the column,
• a second end comprising a planar section with a surface configured to mount parallel to and against the second flange of the beam, and
• a second section of narrowed width between the first and second ends, the narrowed width section defining first and second notches on opposite sides of the yield link, the yield link configured to yield in tension and compression at the second narrowed width section to dissipate stress within the construction upon a lateral load applied to one or more of the beam and column;
• and
• a second buckling restraint plate configured to mount over the second yield link to sandwich the second yield link between the buckling restraint plate and the second flange of the beam.
