МЕТОДИКА ПІДВИЩЕННЯ СТІЙКОСТІ СТИСНУТИХ ЕЛЕМЕНТІВ ФЕРМ ІЗ КУТИКОВИХ ПРОФІЛІВ ЛОКАЛЬНИМИ ТЕРМІЧНИМИ ВПЛИВАМИ
The work is dedicated to the development of design procedures and performance technology of local thermal influences for increase of stability of frаme compressed elements of rolled angle bar of structures. The technique for account of necessary quantity of a thermal energy for creation of residual stress is given. The technique is developed and the experimental researches of influence of residual stress on stability of the compressed elements are carried out. The size and degree of influence of residual stress on stability of the compressed elements of frames of angle bar of structures are determined. The practical technique for increase of stability of the compressed elements of frames executed of angle bar of structures with application of local thermal influences is developed.
