Problem3 The following problem is intended to be solved by hand. For the structure shown below A.) Label the structure degrees of freedom (free only) and number the elements B.) For each element, det...
Analyze the given truss structure using the stiffness method. Clearly state the steps and (matrix) equations used in the problem-solving process. a) Label the degrees of freedom (both free and restrained DOFs) of the structure. b) Determine the stiffness matrix of each element in the local and global coordinates. c) Assemble the structure stiffness matrix Kff considering free DOFs, then write the complete equilibrium equations Kff Uf = Pf and solve for the unknown displacement vector Uf. d) Calculate the...
Problem 5.102: Solve the structure composed of 2 beam and 3 truss elements by taking advantages of the symmetry of structure. (1) Show your half model with proper boundary conditions; (2) How many free DOFs are there in your model? (3) Assemble and show the reduced global stiffness matrix and load vector in your model; and (4) Compute the displacements at Node 2, and element stress in Truss 4 or 5 by following Element and Node IDs as defined in...
