The method and principle of health monitoring of long-span space structure are proposed, and various monitoring methods are described with engineering examples. Respectively steel members, cable, membrane surface stress and welding cracks were monitored and the corresponding monitoring results were obtained. Finally, the wind load effect monitoring, wind pressure and wind vibration monitoring of long-span steel structures are studied. Describes the relevant sensor technology and engineering applications, and put forward some issues to be studied.
