BIAXIAL BENDING OF COLD-FORMED Z-BEAMS

This paper reports the results of ten biaxial bending tests on unbraced, simply supported, cold-formed steel Z-beams loaded at midspan in planes inclined to the major principal plane. These results and those of six beams loaded in the major principal plane are compared with analytical predictions and with simple design approximations. The tests show that the beam strengths decrease as the load inclination to the major principal plane increases and that the strength is higher when the load inclination is toward the web than when it is toward the flange lip. Good agreement is demonstrated between the test results and analytical predictions of the strengths. An extended series of analytical predictions is used to develop simple interaction equations that can be used in the design of eccentrically loaded cold-formed Z-beams.
