THERMAL-INSULATING AND FIRE-RESISTANT GRADED PROTECTION STRUCTURE OF BRIDGE STAY CABLE AND ITS CONSTRUCTION METHOD
Abstract The invention is related to a thermal-insulating and fire-resistant graded protection of bridge stay cable systems. The stay cable has protection structures comprising a first-level protection area with a vertical distance of 11-20 meter from a bridge deck and a second-level protection area with a vertical distance of less than 11 meter from the bridge deck. Each structures comprising a fibre composite wrapping layer formed by winding a fibre composite wrapping tape with a width of 30-50 cm and a thickness of 7-30 mm around a stay cable sheath, and a winding direction at an angle from 15 to 35 degrees. The thermal insulating and fire-resistant protection structures meets different protection standards and enables areas of the stay cable with different protection levels to be set along a height of the cable to meet an objective requirement that the stay cable is subjected to no damage in vehicle fires. -1/4 Ovel First-level protectionarea Second-level protection area 100 200 300 350 400 500 600 700 800 900 1000 Temperature/°C
