英文摘要： An innovative building system integrating functions and structure is proposed, which is assembled with FRP sandwich panels skinned with flexible solar cells to form the non-linear shapes. In this system, the complicated appearance of architecture can be realized with the FRP curved sandwich panels which act the structure and the supporter of functions. The thin film solar cells such as DSC are used to cover on the FRP of the outside surface of the building, which can produce power to supply the building constantly. In this way, the multifunctions, including low carbon, light-weight and high-strength, architecture appearance, and heat insulation, are realized in the same member. In this project, the core member in this system, curved FRP sandwich panels skinned with flexible solar cells, is to be studied in the aspects of the mechanical behavior of panels, the interface and composite action between FRP and DSC, and the mechanical- photovoltaic performance. The key techniques in design and manufacture are to be developed. The large size sample will be manufactured and tested. Through the interdisciplinary research, the fundamental theory and the effective techniques on integrating functions and structure of the presented building system are to be built. All these are promising to provide a practical way to utilize
