76 M10: MECHANICAL CONNECTIONS<br />
20A. Similar to detail 19, but with the segments of the<br />
ridge purlin set flush with the other framing.<br />
23. Similar to detail 22, with added shear plate.<br />
20B. Alternate to detail 20A.<br />
24. Similar to detail 22 for low slope arches. Side plates<br />
replace the threaded rod.<br />
Group 5. Cantilever Beam Connections<br />
21. Hinge connector transfers load without need to slope<br />
cut member ends. Beams are often dapped top and bottom<br />
for a flush fit.<br />
Group 6. Arch Peak Connections<br />
Group 7. Arch Base to Support<br />
Design concepts. Arches transmit thrust into the supporting<br />
structure. The foundation may be designed to resist<br />
this thrust or tie rods may be used. The base detail should<br />
be designed to accommodate the amount of rotation anticipated<br />
in the arch base under various loading conditions.<br />
Elastomeric bearing pads can assist somewhat in distributing<br />
stresses. As noted earlier, the connection should be<br />
designed to minimize any perpendicular to grain stresses<br />
during the deformation of the structure under load.<br />
25. Welded shoe transmits thrust from arch to support.<br />
Note that inside edge of shoe is left open to prevent collection<br />
of moisture.<br />
22. Steep arches connected with a rod and shear plates.<br />
