welded truss, stress-strain state, supporting ability. |

The investigation of the welded roof truss behavior under the complex influence of static and cyclic loads is carried out. The truss is made of the shaped pipes and its size is 24000x2400 mm. The technique of computer simulation experiment by means of SolidWorks Simulation software is used. It is found that the maximum stresses are formed in the area of thermal impact from the weld in the truss heel joints. During the truss operation, these stresses initiate the emergence of fatigue cracks and their growth until the structure ultimate state. The fatigue curve for the investigated structure is constructed. It is determined that the design service life of the truss under operational load modes is going to be 52 years.
