Scope

Scope: This document specifies the requirements for the anti-blast design of oil and gas chemical terminal buildings, including: basic provisions, explosion loads, plane design, architectural design, structural design, HVAC design, control and communication design, and fire protection design. This document applies to the anti-blast design of new, expanded, or modified oil and gas chemical terminal buildings. Main technical content: The following terms and definitions apply to this document. 3.1 Anti-blast building A building designed to protect personnel and facilities within the building and reduce the impact of external explosion accidents on production operations, based on the explosion shock wave parameters determined through explosion safety assessments. 3.2 Air shock wave A longitudinal wave with a sharp discontinuity in air parameters formed by an explosion in the air, referred to as a shock wave. 3.3 Positive pressure of the shock wave The pressure value in the compression zone of the shock wave that exceeds the ambient atmospheric pressure, acting perpendicularly on the surface of the objects surrounded by the shock wave. 3.4 Dynamic pressure The force generated by the rapid movement of gas molecules within the shock wave during its propagation in the air, which has a clear directionality. 3.5 Reflected overpressure The incremental increase in overpressure reflected on the surface of an obstacle encountered by the shock wave during its propagation in the direction of travel. 3.6 Stagnation pressure The overpressure and dynamic pressure acting on the front wall when the reflected pressure from the front wall completely dissipates. 3.7 Peak incident side-on overpressure The overpressure of the shock wave propagating from the center of the explosion outward in free air, reaching the closest surface of the building to the center of the explosion. 3.8 Ductility ratio A measure of the ability of structural components to absorb
