In this study, the lattice roof model was designed in 3 dimensions using the finite element method in the Ansys package program. This method can be understood by making the complex engineering applications is a method to provide the solution can be controlled by the system. The element type of the model, the outside diameter of the truss pipe, the thickness of the meat, the modulus of elasticity and the poisson ratio parameters are defined as material properties. The material is a steel

... c material. A total of mechanical and elastic stress analyzes were carried out under the constant load of 25000 and 20000 kN applied to Fx, Fy, Fz beam axes and 2 MPa pressure on the 3D lattice roof model. Deformations of the model against the load were investigated by analyzing the stresses against the mechanical forces and the elastic stresses in the x, y, z axes. As a result of the analyses, it was observed that the mechanical and elastic stresses in the beam axes against the applied load increased.
