Graphical analysis methods for trusses are divided into the method of joints and method of moments. Mohr's stress and strain circles are discussed along with the extension to three-dimensional problems. Then the computational method is used for the solution of the same problems. Analysis of Trusses The analysis of trusses is usually based on the following simplifying assumptions: •The centroidal axis of each member coincides with the line connecting the centers of the adjacent members and the members only carry axial force. At the beginning, the analytical method is used for determination of values of external supports, axial forces and principal stresses in truss. Trusses: Method of Joints Frame 18-1 *Introduction A truss is a structure composed of several members joined at their ends so as to form a rigid body. A truss is a structure that consists of triangular units composed of linear rigid members whose ends are connected at joints. The Nature of forces is importantly availed here.
