With the increasing threat of localized conflicts and full-scale wars due to global geopolitical tensions—including the ongoing wars in Ukraine and the Middle East, North Korea’s nuclear threats, and China's expansionist policies—the importance of protective facilities for civilians and public infrastructure has become paramount. In South Korea, where over half of the population resides near the demilitarized zone, civil protection during wartime is a critical national concern. While there are over 14,000 designated civilian shelters, most lack sufficient protective capabilities, particularly against nuclear or high-explosive attacks. This study introduces the newly developed Standards for Protective Facilities and Explosion-Proof Facility Design Standards, published by the Korean Society of Protective Facilities Engineering. The standards aim to provide unified guidelines for designing, assessing, and upgrading both new and existing civil and public protective structures. The paper outlines structural performance levels required for various protection grades, explains simplified blast load models, and details the design procedures for reinforced concrete protective structures under explosive loads. It also includes practical classification criteria for blast damage levels and introduces methods for pressure-time response analysis, dynamic load amplification, and structural detailing strategies to ensure occupant safety and functionality under attack scenarios. These standards are expected to serve as essential tools in enhancing national civil defense infrastructure in a cost-effective and scalable manner.
