The steel used for the frame has the same tensile strength, fu, and compression strength, fo, i.e. f=f=fc = 250 MPa (= 250 N/mm²). The horizontal load on the frame as shown in Fig. 2.1 is P = 20 kN, q = 8 kN/m. Q2.5: Consider the normal force and moment diagrams in Q2.3. Which points in the frame may be critical when considering the normal stress? Which combinations (N, M) are you going to consider? Q2.6: For all the (N, M)-combinations mentioned in Q2.6 show the normal stress distribution over the cross section for P = 20 kN, q = 8 kN/m. (Show the normal stress distribution stemming from the normal force N, show the normal stress distribution stemming from the moment M, and show the resulting normal stress distribution for Nand M acting simultaneously).
