Problem 6.101: A structure is composed of two CST elements, and is subjected two concentrated forces...
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...
