Truss Analysis by Joints Problems

CIV E 321 Fall, 2022 – Global Campus Structural Analysis I Dr. R. K. Dowell HW 1 Truss Forces by Method of Joints For the truss structures given below, determine reactions and member forces by the Method of Joints. Prior to solving each problem, determine if the structure is stable and statically determinate. Identify zero-force members, where possible, before solving for member forces to reduce the required calculations. 100 kips A B D C 9 ft H F G 30 kips 60 kips 3@10 ft = 30 ft 10 kips 5 kips 10 kips E D E 5 ft A B C 20 kips 16 ft 15 kips 16 ft D C 40 ft B E 12 kips 40 ft F A 30 ft
