welded truss, thermal influence, temperature deformations.

The article studies some deformation features of the full-scale physical model test of the 2000x400 mm rectangular welded truss at thermal influence ranging from 20 to 160°C. Numerical information based on the values of deformations at seven control points of the truss for chords and nodes was obtained as a result. A computer simulation experiment using SolidWorks software for similar impact parameters on truss was performed. Results comparison of full-scale physical model deformation and computer simulation experiments revealed its similarity. Experimental results can be used in determining the parameters of the stress-strain state of the elements of the trusses under simultaneous force and temperature effects.
