2. Model the truss provided below in SAP2000. Give all members a cross-sectional area of 2.0 in2 and I 35 in. Use the steel material (E 29,000 ksi). Find all of the bar forces and report them in a table. Now remove all point loads and then apply a downward vertical point load of 110 k at point E. Find all...

Problem 5 (20 points): You are working as a consultant and your client presents the following schematic for a proposed roof truss design. The truss consists of 7 identical sections measuring 5 ft by 5 ft and subjected to 6 identical 200 lb loads. Find the forces in members AB, AC, BC, BD, and CD. Indicate on a sketch of the truss which members are zero force. What feedback on the proposed design would you give to your client? é...
5. (20 points) The truss shown below supports horizontal forces of 6 kips at Joint G, 8 kips at Joint E, and 4 kips at Joint C. All truss members are made of steel (E 29,000 ksi). Each of the diagonal members (Members AD, DE, and EH) has a cross-sectional area of 1.2 in2. Each of the vertical members (Members AC, CE, EG, BD, DF and FH) has a cross-sectional area of 2.4 in Each of the horizontal members (Members...
Problem 1: A lateral load resisting system of a 4-story building consists a K-truss and is shown in the figure below.
