Development of Approaches to Estimating the Breaking Strength of Steel for Building Metallic Structures and Modern Standards

Abstract

The service properties of the steels intended for metallic constructions that are regulated by new standards and the standards that have recently been operative are compared. The validity of the transition to impact toughness standardization using specimens with a sharp notch instead of earlier specimens with a semicircular notch (transition from KCU to KCV) is grounded. The correlation of KCV as a structural strength parameter with other service properties of the steels intended for metallic constructions is discussed.
