Scaffoldings falling-off accidents during demolition works of buildings exterior walls are one of the major issues in labor and public safety in construction. This paper proposes a new strengthening system for scaffoldings, which are inevitably in freestanding condition after the supporting wall have been demolished. Indoor experiment as well as on-site experiment at real demolition site are conducted to verify the strengthening performance of the system against wind. It has been shown that the developed system has sufficient performance at required wind conditions and effectively suppress the displacement of scaffolding so that the system enables to prevent the falling-off accidents of scaffoldings themselves as well as construction workers on the scaffoldings.
