Figure 146.1 Reinforced Concrete Beam Problem Sketch ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–323 VM146 Material Properties Concrete (material 1) E = 2 x 106 psi σct = 0.0 psi υ = 0.0 Steel (material 2) E = 30 x 106 psi υ = 0.3 Geometric Properties b = 5 in d = 6 in A = 0.30 in2 Loading M = 600 in-lb Analysis Assumptions and Modeling Notes The bottom concrete element is lined with two spar elements to match the assumption given in the reference of discrete (rather than smeared) reinforcement. A zero Poisson's ratio and an infinite crushing strength are also assumed for the concrete to match the reference assumptions. An element width (in the X-direction) of 1.5 in. is arbitrarily selected. Constraint equations are used along the beam depth to conveniently apply the load and match the reference assumption that cross-sections remain plane. Dummy PIPE16 pipe elements are used to "line" the constraint equati...
