1. Record the dimensions of portal frame members and calculate their second moment of area in Table 1. (1 mark).< Table 1 Geometric properties Element Width, b Length, L (mm)< Uu Depth, d (or thickness) (mm) 1 = (mm²) (mm) (refer to Figure 2 124 in the handout) Beam 19,9 3.0 495 44.775 Column 19.9 3.0 250 44.775 2. Record the strain values at different levels of loading in Table 2.
