Abstract: This project is to solve the following 5 key scientific problems:(1)Building facade thermal insulation material fire property and safety design;(2)Fire spread in high-rise building and structure safety;(3)Multi-force aided smoke tranportation and multi-modes human evacuation Research items and goals: Reveal fire behavior thermal insulaiton materials; develop fire safety evaluation method for thermal insulation material; reveal fire spread behavior in high-rise buildings; reval structure response and safety of high-rise building in fire; reveal smoke transportaion behavior in high-rise building; develop multi-mode human evacualtion strategy. Five sub-projects;(1)Fire behavior and safety design for facade thermal insulation materials;(2)Fire spread behavior and control in high-rise buildings;(3)Structure response and safety of high-rise biulding in fire; (4)Fire smoke transportation and control in high-rise building;(5)Multi-modes crowds evaculation behavior and strategy. The funding budget is 36 000 000 Yuan.
Key Words: High-rise building; Fire; Proection; Thermal insulation material; Structure safety; Smoke control; Human evacuation
