Abstract
The fatigue failure modeling of welded rectangular truss 4954 х 1596 mm size with gusset plates joints under external cyclic loading was studied in the paper. The sample is made of steel shaped tubes with various cross section areas. Loading and support schemes that identify the operating mode for this type of structure were selected. According to the results of computer simulation experiment in ANSYS Workbench 19.1 the stress value of welded truss nodes and the fatigue sensitivity curve were obtained. The results obtained in the paper can be applied both in the design of new trusses to prevent the destruction of structures in service.
