A structure is fabricated by welding together three lengths of I-shaped members as shown in Figure..


A make is simulated by welding concomitantly three lengths of I-shaped members as shown in Figure P5–44. The comply ability of the members is 36 ksi, E = 29  106 psi, and Poisson’s association is 0.3. The members all possess cross-minority properties selfsame to a W18  76. That is, A = 22:3 in2, profundity of minority is d = 18:21 in., Ix = 1330 in: 4 Sx = 146 in: 3 Iy = 152 in: 4 and Sy = 27:6 in: 3 State whether a load of Q = 10;000 lb downward is safe opposing public complying of the esthetic. The constituent of security opposing public complying is to be 2.0. Also, state the ultimatum upright and horizontal deflections of the make.
