Вплив циклічного знакозмінного навантаження на міцність, тріщиностійкість та деформативність прогінних залізобетонних елементів

Abstract

Posed and partially solved the problem by creating scientific and research complex stress-strain state of reinforced concrete beam elements influenced by alternating short malotsyklovoho load. The features of the stress-strain state of prototypes girders experiencing little-cyclic alternating load highs. For the first time the dependence of the nature and type of the destruction of their neighborhood of reference sites on the proportion of structural factors and factors of external influence. Systematized known and identified new schemes destruction of these elements under the action of said load.
