Study on Mechanical Behavior of Floor Beams in the High-Strength Cold-Formed Steel Framing System
Tests and the finite element method (FEM) have been used to research the mechanical behavior of floor beams in the new cold-formed steel framing system. A group of 3 floor beams have been carried loading test to obtain ultimate bearing capacity, then finite element models, using plastic shell element and simultaneous considering material and geometric nonlinearity in ANSYS, have been established to analyze the mechanical behavior of floor beams. Finally, the ultimate uniform loads are given for the various specifications of floor beams, for practical engineering design.
