Diaphragm to lateral support coupling in a structure
An example system is disclosed that may include a diaphragm, a pair of C-channels coupled to the diaphragm, a horizontal beam having two opposite ends, a pair of collars configured to slide onto the two opposite ends of the horizontal beam, the pair of collars each including a flange around a perimeter of each of the pair of collars, the flange configured to couple to an end of each of the pair of C-channels, a pair of columns coupled to the two opposite ends of the horizontal beam, and a brace coupled to at least one column of the pair of columns and the horizontal beam. An example method is disclosed for translating a lateral load from a diaphragm to a lateral load support system.
1. A system, comprising:
a diaphragm having two parallel edges;
a first pair of horizontal plates coupled to the two parallel edges;
a first pair of vertical plates coupled to the two parallel edges;
a pair of C-channels, each having a channel surface and a flat surface;
a second pair of horizontal plates coupled to the flat surfaces of the pair of C-channels, wherein the second pair of horizontal plates is further coupled to the first pair of horizontal plates;
a second pair of vertical plates coupled to the flat surfaces of the pair of C-channels, wherein the second pair of vertical plates is further coupled to the first pair of vertical plates;
a horizontal beam having two opposite ends;
a pair of collars configured to slide onto the two opposite ends of the horizontal beam, wherein the pair of collars each include a flange around a perimeter of each of the pair of collars, and wherein the flange is configured to couple to an end of each of the pair of C-channels;
a pair of columns coupled to the two opposite ends of the horizontal beam; and
a brace coupled to at least one column of the pair of columns and the horizontal beam.
2. The system of claim 1 , further comprising a thermal break material between the first and second pairs of horizontal plates.
3. The system of claim 1 , further comprising a thermal break material between the pair of collars and the pair of C-channels.
4. The system of claim 1 , wherein the horizontal beam is coupled to a vertical column of the pair of columns by a respective said plate, and wherein the system further comprises a thermal break material between the vertical column and the respective plate.
5. The system of claim 1 , wherein the diaphragm includes a plurality of panels coupled together.
6. The system of claim 1 , wherein at least one of the diaphragm, the first pair of horizontal plates, the first pair of vertical plates, the pair of C-channels, the second pair of horizontal plates, the second pair of vertical plates, the horizontal beam, the pair of collars, the pair of columns, or the brace comprises metal.
7. The system of claim 1 , wherein at least one of the diaphragm, the first pair of horizontal plates, the first pair of vertical plates, the pair of C-channels, the second pair of horizontal plates, the second pair of vertical plates, the horizontal beam, the pair of collars, the pair of columns, or the brace comprises wood.
8. The system of claim 1 , wherein the horizontal beam comprises an I-beam, wherein the I-beam includes a pair of smaller C-channels at each end, and wherein the pair of smaller C-channels are configured to fit into channels defined on either side of the I-beam.
9. The system of claim 8 , wherein the I-beam is enclosed in a fire retardant material.
10. The system of claim 8 , wherein the I-beam is enclosed in a thermal break material.
