Scope

Main technical content: (1) Regarding the scope of application, this standard applies to newly constructed (or modified/expanded) steel or reinforced concrete bridges, arch bridges, rigid frame bridges, cable-stayed bridges, suspension bridges, and other steel structures or reinforced concrete structures, as well as lightning protection devices for artificial islands and tunnels. (2) Regarding terms and definitions, to provide a more comprehensive understanding of this standard, it provides 15 terms and definitions related to lightning protection technologies for integrated bridge-island-tunnel structures. (3) General provisions: It proposes a general requirement for lightning protection devices for integrated bridge-island-tunnel structures, including the composition of lightning protection devices, the division of lightning protection zones, lightning protection classification, grounding, and the composition of lightning approach warning systems. (4) Direct lightning protection: The standard specifies requirements for lightning arresters, down conductors, and grounding devices in lightning protection devices for integrated bridge-island-tunnel structures. (5) Protection against lightning electromagnetic pulses: The standard sets out general and special requirements for equipotential bonding and shielding, as well as surge protectors (SPDs) in lightning protection devices for integrated bridge-island-tunnel structures. Surge protectors include general requirements for bridge-island-tunnel structures and requirements for power and signal circuits. (6) Lightning approach warning: The standard specifies specific requirements for the design, installation, and maintenance of lightning approach warning systems for integrated bridge-island-tunnel structures, including requirements for warning processes, grade settings, release targets, installation of lightning approach warning systems, maintenance of lightning approach warning systems, and methods, functions,
