Problem 6.101: A structure is composed of two CST elements, and is subjected two concentrated forces at the center node of the structure as shown in the figure. Please take advantages of the symmetry of structure to simplify the analysis of the problem with dimension D-10. Answer the following questions (hand-calculation only): 1) Show your FE models with proper boundary conditions and applied loads; 2) Compute reduced stiffness matrix and loads vector of your models; and 3) Compute the nodal...
