Unformatted text preview: 5. Determine the support reactions and check global equilibrium [1 point]. 6. Draw the deformed shape of the structure [1 point]. University of California, Berkeley Dept. of Civil and Environmental Engineering Spring Semester 2009 2 2. Problem (5 points) The structure model below has a column with flexural stiffness and girders with flexural stiffness ? and a brace with axial stiffness . The frame elements have negligible axial deformations. 1. Determine the structure stiffness matrix in terms of , ? , and [3 points]. 2. Setup the vector for the distributed load shown [1 point]. 3. Setup the vector for a thermal curvature = 2 10 3 on the girders (elements b and c). For this question, assume ? = 50,000 [1 point]....
