During　the　service　of　single-layer　plane　cable　net　supported　glass　buildings,　as　the　supporting　structure　the　single-layer　plane　cable　net　will　inevitably　be　subjected　to　different　types　of　damages.　In　order　to　study　the　influence　of　such　damages　on　the　static　behavior　of　the　single-layer　plane　cable　net,　a　full-scale　model　with　the　dimension　of　4.85　m　×　4.85　m　and　4　×　4　grids　was　designed　and　constructed.　Static　tests　were　conducted　after　introducing　three　types　of　damages　including　failure　of　connectors　between　horizontal　and　vertical　cables,　cable　prestress　loss　and　cable　anchorage　failure.　The　results　indicate　that,　failure　of　connectors　between　horizontal　and　vertical　cables　almost　has　no　influence　on　the　static　behavior　of　the　single-layer　plane　cable　net;　the　change　of　nodal　displacements　induced　by　the　cable　prestress　loss　does　not　exceed　15%;　the　cable　anchorage　failure　affects　the　local　part　of　the　single-layer　plane　cable　net　significantly,　and　the　induced　change　of　nodal　displacements　is　between　18%　and　36%;　damages　have　stronger　effect　on　nodal　displacements　than　cable　tension　forces.　The　intensity　of　the　influence　of　damages　depends　on　the　damage　degree　and　location,　and　decreases　with　the　increase　of　load.　The　research　results　provide　a　sound　foundation　for　establishing　the　safety　evaluating　method　of　in-service　single-layer　plane　cable　net　structures.
