On the work of steel two-tauri on longitudinal efforts

The article reviews the work of thin corrugated wall of steel I-shaped on the longitudinal efforts in flexural elements. The numerical experiment in program complex LIRA-SAPR is made to assess the relative value of the zone of thin corrugated wall with a triangular profile of the corrugations, working together with the belts on the longitudinal forces. The mathematical analysis of the stress-strain state of the 75-corrugated beams is produced to give the maximum and minimum values of the corrugated wall, working together with belts beams. The fractional and sedate regressions are received.
