Analytical calculation of bending elements with basalt fiber and glass composite rod reinforcement under short-term dynamic loading

During the construction and operation of buildings and structures, in addition to static loads, short-term dynamic impacts may occur on building structures and their elements caused by explosions, accidents, etc. As a result, damage or destruction of structures may occur, which leads to possible loss of life and significant material losses. Taking into account the influence of such impacts on the load-bearing capacity of building structures is relevant. A significant number of works by domestic and foreign authors are devoted to methods for calculating bending reinforced concrete elements under static and short-term dynamic loading. In the overwhelming majority, bendable concrete elements with steel rod and/or fiber reinforcement are considered as the object of research. The issues of predicting and assessing the stress-strain state of bending concrete elements reinforced with glass-composite reinforcement and/or basalt fiber under short-term dynamic loading have not been sufficiently studied. The current building codes consider calculations of such elements only under the action of static loads.
