Statistical Analysis of Effective Parameters on Displacement Joints in Pratt Truss and Providing an Appropriate Model for Predict
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, with using statistical analyses methods effects of per parameters such as material, diameter of bar, ap...
