Application and Research of Steel Structure Construction Monitoring of Costa Rica State Stadium Canopy

State Stadium of Costa Rica is the key supporting-construction project of China, because Costa Rica is located in the volcanic active belt in west pacific coast watershed of central American, it is a country there often happens earthquakes. Internal and external arch of the scheduling stadium canopy is a big spanned and high height steel structure. In order to improve construction quality, and to ensure construction accuracy, it needs to do construction deformation and stress monitoring for the key parts during steel structure support dismantling and pre-stressing tension. The paper had done steel structure construction monitoring of Costa Rica state stadium canopy with wireless intelligent strain remote measurement system and measurement robot, got a satisfied and good result.
