"QC.25. Figure below shows a nonsway frame. The following are the properties of the beams and columns: For beams AD and AE cross section is 330 by mm 500 mm. For beams BF and BG cross section is 330 by 570 mm and columns AB to AC is 330 by 530 mm. Also, the lengths in meters are L1 = 5.3, L2 = 5.6, L3 = 6.1, and L4 = 7.2 meters. The column AB is bent in single curvature about its y- axis. It is carrying a total factored axial load of 560 kN with an unfactored dead axial load of 196 kN. The factored end moments are 111 and 119 kN-m.

An engineer is designing a beam to support a flooring system above it, as well as two walls. The beam will be a T-section, though the engineer is considering the idea of combining timber and steel to create a composite member for the application. The dimensions of the T-section beam are shown below: dw The dimensions of the T-section beam are shown below: bf Flange (horizontal section of cross-section): • bf = 340 mm tf = 15 mm ● Walls Flooring Beam
