1.054/1.541 Mechanics and Design of Concrete Structures Spring 2004Prof. Oral Buyukozturk 1 / 71.054/1.541 Mechanics and Design of Concrete Structures (3-0-9) Design Example Shear and Torsion Objective: To examine the adequacy of given cross section based on shear and torsion capacities. Problem: At a section of a beam, the internal forces are Vu= 45 kips, Mu= 300 kips-ft, and Tu= 120 kips-ft. The material strengths are f’c= 4 ksi and fy= 60 ksi. Assume that the distance from beam faces to the center of stirrups is 2 in and d is 21 in. aaMassachusetts Institute of TechnologyFigure 1. Plan view of overpass 24‘’16‘’TuMuVuFigure 2.
