Study of Material, Diameter, Loading and Internal Angles Effects on Joints Displacements in Truss Members

Trusses is one of most usable structures in engineering. Truss is combination of bar elements created. Triangle shape is most stable possible are formed by bar elements in truss. In this research, effects of variations in internal angles, elastic modulus, diameters and loading on truss members and displacement in joints were evaluated. For this purpose, 45 models in Sigma/w analyzed. Results of present study showed that with decreasing elastic modulus in members, vertical and horizontal displacement in joints increase. Also, horizontal displacement in supports with two freedom degree is more than supports including one freedom degree.
