Moment-resisting frame
Disclosed herein is a moment-resisting frame for connecting beams and columns of a structure. The moment-resisting frame may include a beam comprising a top horizontal flange, a bottom horizontal flange, and a vertical web fitted securely between the top horizontal flange and the bottom horizontal flange. The moment-resisting frame may also include a column comprising a lateral vertical flange. The lateral vertical flange may include a top flange threaded hole, a bottom flange threaded hole, a first lateral flange threaded hole, and a second lateral flange threaded hole. The moment-resisting frame may further include a plurality of rows of coplanar plates that retrofitted around an outermost periphery of the beam.
1. A moment-resisting frame, comprising:
a column comprising a lateral vertical flange, the lateral vertical flange including a top flange threaded hole, a bottom flange threaded hole, a first lateral flange threaded hole, and a second lateral flange threaded hole;
a beam comprising a top horizontal flange, a bottom horizontal flange, and a vertical web fitted securely between the top horizontal flange and the bottom horizontal flange, the vertical web including a first side and a second side;
a plurality of rows of coplanar plates, the plurality of rows of coplanar plates arranged in a parallel configuration relative to the lateral vertical flange, each row of the plurality of rows of coplanar plates comprising:
a top plate including a top threaded hole associated with the top flange threaded hole, the top plate attached horizontally to a top side of the top horizontal flange in a perpendicular configuration relative to a main axis of the beam;
a bottom plate including a bottom threaded hole associated with the bottom flange threaded hole, the bottom plate attached horizontally to a bottom side of the bottom horizontal flange in a perpendicular configuration relative to the main axis of the beam;
a first lateral plate including a first lateral threaded hole associated with the first lateral flange threaded hole, the first lateral plate attached vertically to the first side of the vertical web in a perpendicular configuration relative to the main axis of the beam; and
a second lateral plate including a second lateral threaded hole associated with the second lateral flange threaded hole, the second lateral plate attached vertically to the second side of the vertical web in a perpendicular configuration relative to the main axis of the beam.
2. The moment-resisting frame of claim 1 , wherein:
the top plate is secured into a substantially fixed position by a top lock screw inside the top threaded hole and the top flange threaded hole;
the bottom plate is secured into a substantially fixed position by a bottom lock screw inside the bottom threaded hole and the bottom flange threaded hole;
the first lateral plate is secured into a substantially fixed position by a first lateral lock screw inside the first lateral threaded hole and the first lateral flange threaded hole; and
the second lateral plate is secured into a substantially fixed position by a second lateral lock screw inside the second lateral threaded hole and the second lateral flange threaded hole.
3. The moment-resisting frame of claim 1 , wherein the lateral vertical flange is located opposite to the beam.
4. The moment-resisting frame of claim 1 , wherein the lateral vertical flange has a substantially rectangular shape.
5. The moment-resisting frame of claim 1 , wherein the top horizontal flange, the bottom horizontal flange, and the vertical web have a substantially rectangular shape.
6. The moment-resisting frame of claim 1 , wherein the first lateral plate and the second lateral plate are attached horizontally to a bottom side of the top horizontal flange and a top side of the bottom horizontal flange.
7. The moment-resisting frame of claim 1 , wherein the top plate, the bottom plate, the first lateral plate, and the second lateral plate are attached to the beam by welding process.
8. The moment-resisting frame of claim 1 , wherein the beam, the column, the top plate, the bottom plate, the first lateral plate, and the second lateral plate are manufactured from stainless steel 37.
9. The moment-resisting frame of claim 1 , wherein the top lock screw, the bottom lock screw, the first lateral lock screw, and the second lateral lock screw are manufactured from high strength steel.
10. The moment-resisting frame of claim 1 , wherein there is a gap with a width ranging between 1 cm to 5 cm between an outer vertical section of the beam and an outer surface of the vertical flange.
11. The moment-resisting frame of claim 1 , wherein the top lock screw, the bottom lock screw, the first lateral lock screw, and the second lateral lock screw are secured into a substantially fixed position by a plurality of nuts.
