Unformatted text preview: EI=100,000 units. The brace element d has axial stiffness EA = 30,000 units. Use the displacement method of analysis to answer the following questions, even though the force method would involve less equations: 1. Identify the independent free global dofs. 2. Determine the coefficients of the stiffness matrix for the structure (it should be a 4x4 matrix). 3. Solve for the global dof displacements under the given uniformly distributed element load. 4. Determine the basic forces and draw the bending moment diagram. 5. Determine the maximum and minimum moment in element c. 6. Draw the deformed shape of the structure under the given loading. 7. Determine the support reactions and check global equilibrium. 8 8 6 a b c d 1 2 3 4 w=5...
