A compound steel column consists of two square concrete segments is shown in Figure Q4(b). Segment 1 has 100 mm edges and segment 2 has 150 mm edges. The column is subjected to torques of TB = 8 kNm and Tc = 12 kNm to act in the direction given in Figure Q4(b). Take Gsteel = 81GPa. (i) Determine maximum shear stress and angle of twist at point C. (ii) In your opinion, what shapes of cross section that prone to torsional bucking. Provide your judgements. T= 12 kNm C B T₂ = 12 kNm 100 mm FIGURE Q4(b) 150 mm
