E M O R A N D U M TO: Dr. Kuang-An Chang Instructor, CVEN 302, Fall 2010 FROM: Ryan Henry 219003331 DATE: October 22, 2010 RE: Analysis of a Statically Determinant Truss In this program, I wrote user defined functions to define a Matrix [A], define a solution column vector {b}, and use Gaussian elimination to solve for the solution vector {x}. I then wrote a wrap- per program to run all of these functions. The x-value table below is a list of our solution vectors {x} for various inputs of F. X-VALUES FOR VARIOUS CASES F = [0 -3000] F = [0 -3000] F = [-1500 1200] F = [0 -1500] f_node = 8 f_node = 9 f_node = 14 f_node = 4,7,9,12,15 x = x = x = x = 1.0e+003 * 1.0e+004 * 1.0e+004 * 1.0e+004 * -6 -1.2 -2.28 -1.65 -9 -1.9 -4.23 -2.35 - 8.4853 - 1.6971 - 3.2244 - 2.3335 -3 -0.7 -1.95 -0.7 6 1.2 2.28 1.65 6 1.2 2.28 1.65 0 0 0 0.15 - 3.3541 - 0.6708 - 1.2746 - 0.8385 3.354 1 0.670 8 1.274 6 0.838 5 -3 -0.7 -1.95 -0.7 3 0.6 1.14 0.75 4.5 0.9 1.71 1.275 -3 -0.6 -1.14 -0.6 - 3.3541 - 0.6708 - 1.2746 - 0.7547 Zachry Department of Civil Engineering, 3136 TAMU, College Station, TX 77843-3136.
