Conclusions
-
1.
On the basis of analyzing the working conditions of elements of the lock gates on the Moscow Canal and on-site strain measurements the low-cycle character of loading and the possibility of failure in the maximally stressed zones as a consequence of the occurrence of repeated elastoplastic deformations in the structural material was confirmed.
-
2.
It is necessary to calculate and determine experimentally the low-cycle life of elements of the load-bearing structures of lock gates and to work out recommendations on increasing their resistance to cyclic failure.
