Anotace

This specification covers a procedure for evaluating metal devices used for wood-to-wood, wood-to-concrete, wood-to-concrete masonry, and wood-to-steel joist, beam, and girder connections. It describes test methods for evaluating the capacities of joist hangers subject to vertical and torsional loading. Also, this specification provides a method of assigning allowable loads to joist hangers based on measured strength and deformation characteristics. Test specimens consisting of a length of joist supported by joist hangers attached to two headers are subjected to a vertical load by a suitable testing machine, while the vertical load and corresponding deflection of the joist are measured and recorded to provide load-slip data.
