Unformatted text preview: UNIVERSITY OF CALIFORNIA, BERKELEY Department of Civil and Environmental Engineering Spring Semester, 2005 Instructor: A. K. Chopra CE 130 MIDTERM EXAMINATION NO. 2 Please Note: 1. Write your answers on these sheets. 2. Show all computations; identify your answers. Problems Maximum Points Points Scored 1 8 2 10 3 12 Total 30 NAME: 1. A T-beam shown in the figure is made of a material with tensile proportional limit of 3000 psi and a compressive proportional limit of 6000 psi. If these stresses are not to be exceeded, find the magnitude of the largest force F which may be applied to this beam in (a) downward direction (b) upward direction. Consider only the bending stresses obtained from the flexure formula. For the given T-section the neutral axis (n-a) is 5.5 in. from the bottom and I = 97 in 4 about the n.a. 2. A box beam is fabricated by nailing plywood sides to two longitudinal wooden pieces, as shown in the figure. If the vertical shear at a section is V = 12 kN, determine: (a)...
