Transformed Area Method (Concrete Cracked - Elastic Stresses Stage) Problem 2) Modified Problem 2.13 (page 55, McCormac and Brown, 10th Ed.) Change f'c to 5 ksi and cross-sectional properties See figures below. 30 kip W = 2 kip/ft A 10 ft. 20 ft. 30 ft. f'. = 5000 psi 30 in. 36 in. 8 #9 bars 3 in. 3 in. 16 in. (a) Find the reactions at A and B. RA = kip, RB = kip ft*kip (b) Determine the maximum applied moment. Mmax = (c) Calculate the cracking moment of the beam and verify that the beam has cracked under the applied loads. Mer = ft*kip in3 Moment of inertia of gross section, Ig = Modulus of Rupture f, = (d) Calculate the cracked moment of inertia. Note that you will need to first calculate the concrete psi modulus of elasticity and modular ratio. Do not use the textbook modular ratio of n=8. Ec = psi (use the simplified equation for normal weight concrete) Modular ratio, n =
