| Summary: | The article discusses the issues of fatigue fracture of steel structures and the method of increasing their strength through the use of reinforcing elements. The authors set the search for ways to improve steel structures and to reduce their metal intensity without reducing strength and increasing their resistance to fatigue failure, except for the use of expensive high-strength alloys. They have proposed a method for strengthening the structure and searching for its optimal shape of the loaded part, capable with a smaller wall thickness to withstand fatigue failure of steel structures of mine hoisting machines used to transport metallurgical coke in long-term operation. The results of computer modeling the stress-strain state of a steel beam under operating loads are given. |
