CALCULATION OF A CONCRETE WALL DAMAGED BY AN EXPLOSION FOR FRAGMENT PENETRATION ACCORDING TO THE UFC 3-340-02 METHODOLOGY

Abstract

The article examines the evolution of building codes for designing structures resistant to blast effects in the United States and Europe. It analyzes the historical background that contributed to the development of modern standards, particularly UFC 3-340-02 and the Eurocodes. Special attention is given to the methodology for assessing damage to protective structures caused by fragments generated during explosions. An algorithm is presented for determining the required wall thickness to prevent perforation and spalling, taking into account the characteristics of explosive projectiles. The study offers recommendations for enhancing the design methodology of blast-resistant structures.
