University of California, Berkeley Dept. of Civil and Environmental Engineering Spring Semester 2009 1 CE 121 — Advanced Structural Analysis Homework Set #5 (due Feb. 28, 2009) 1. Problem (5 points) All frame elements in the structural model have negligible axial deformations. All elements are heated up so that a uniform thermal curvature field of 8 × 10 −4 rad per unit of length results (recall how a positive curvature is defined in the element coordinate system that points from lower to higher numbered node). 1. Determine the displacements at the free DOFs ° ± . 2. Draw the deformed shape of the structure.

Unformatted text preview: Spring Semester 2009 2 2. Problem (5 points) The frame elements of the structural model (elements a through c) have negligible axial deformations. Elements a and b are heated up so that a uniform curvature field of 110-3 rad per unit of length results. 1. Determine the compatibility conditions that the deformations of elements c and d need to satisfy. 2. Use the compatibility conditions to determine the necessary initial deformations of elements c (initial camber) and d (lack of fit). 3. Determine the free dof displacements of the structural model. 4. Draw the deformed shape of the structural model. 5. Determine the rotation at node 4....
