RESEARCH AND DEVELOPMENT IN SEISMIC PERFORMANCE OF FRP REINFORCED CONCRETE COLUMNS AND STRUCTURES

Abstract

Abstract: Compared with ordinary steel rebars, FRP bars have the characteristics of high tensile strength, light weight and non-corrosive. However, FRP bars have low elastic modulus, being linear elastic materials and having great brittleness at failure, which limit the application of FRP reinforced concrete columns, especially the structural engineering in the seismic region. This paper briefly introduces the main progresses in the studies on seismic performance of FRP reinforced concrete columns and structures, in which the experimental and numerical simulation investigations are included. The results show that it is practicable to arrange FRP bars instead of steel rebars in concrete columns, concrete frames and frame joints. FRP reinforced concrete structures can develop better ductility and deformation capacity when FRP bars are arranged properly in the elastic range. In the end, this paper proposes conducting further researches on the failure modes, calculation method of shear resistance, ductility assessment and design theory of FRP reinforced concrete columns. It is of theoretical significance and practical value to investigate the basic theory and design method of FRP reinforced concrete columns systematically
