WELDED-WELDED FRAMING ANGLE CONNECTIONS

摘要

Results of tension and compression tests on angle segments are used to generate moment-rotation curves for welded-welded double framing angle connections. The beam line concept is then used to determine the connection moments for connection depths of 18 to 32 inches. With the connection moments known, the two welds, denoted as Weld A and Weld B in the AISC Manual Table IV are evaluated. Because the analytical model used to generate the weld sized published in the AISC Manual and analytical model used in this research differ, it was found that the capacities of the connection designs in the AISC Manual for Weld B have factors of safety ranging from 2.5 to 3.0. Design aids are included which give the connection moments for a variety of designs as a function of the length to depth ratio of the beam for the case of uniform loading.
