英文摘要： To enhance the thermal efficiency of external wall panels is the key work about building energy conservation.The traditional thermal panels expose their drawbacks after years of use, such as the thickness and heavy self-weight of panels which is inconvenient for transportation, the corrosion of metal connections and the cold bridge which seriously decreases the thermal insulation behavior of panels.The project tends to devolep a new thermal sandwitch wall panels using the light and low thermal conductivity material-Fiber Reinforced Polymer(FRP).The wall composed of the glass fiber-reinforced polymer(GFRP) skins and low-density polyurethane core which connected by the FRP shear connectors. The project is based on the theoretical analysis and tests methods, to determine.the mechanical performance and calculation formulas for new GFRP connectors, study the parameters and failure mechanism of GFRP sandwich panels, explore the thermal and mechanical behavior of GFRP sandwich panels, then put forward the reasonable forms and analysis methods of GFRP sandwitch wall panels. This study is very important to the sustainable development and building energy-saving target of 65% and will bring remarkable econimic benefit and social benefit.
