Abstract


Fiber-reinforced composite material ( Fiber Reinforced Polymer referred to as FRP) has high strength , light weight , corrosion resistance , convenient construction , etc. , its materials not only can be used in areas such as aviation, military , and is now widely used in civil engineering , water conservancy , transportation engineering and other fields . FRP in the field of civil engineering , both directly as a structural material for the new structure , but also as a reinforcement material reinforced building structure . Currently, most of the literature is a the FRP confined ordinary reinforced concrete members or reinforcement ordinary reinforced concrete structure , less FRP confined SRC member or reinforcement steel reinforced concrete structure . Therefore, theoretical analysis and numerical simulation of the FRP SRC force performance , this paper research and content as follows: theoretical study and analysis of three different failure modes of FRP Reinforced steel reinforced concrete beam FRP steel reinforced concrete beam bending capacity of the characteristics of each failure mode (mainly three kinds of failure modes , and each failure mode , there are three cases : in steel reinforced top flange and shaft through ; neutral axis by SRC web; neutral axis through SRC ) section bearing capacity of FRP Reinforced Concrete Beam derived formula . Analysis of the FRP plates SRC Beams force characteristics , can be divided into : U-shaped paste L - type paste , wrapped paste FRP cloth oblique section reinforcement , this article is not only to analyze the impact of the different paste and Ultimate Shear Capacity of FRP SRC formula is also derived to verify its correctness , and finally by the experimental data . Analysis on the basis of existing FRP confined concrete computational model , the strength of FRP confined rectangular concrete columns correction formula obtained by regression analysis , the superposition method formula derived FRP confined cylinder and bearing capacity of FRP confined rectangular columns . The whole process of FRP steel reinforced concrete flexural members nonlinear analysis, nonlinear program FORTRAN language , nonlinear analysis of beam bending moment - curvature curve and the load - deflection relationship . This method of analysis takes into account not only the characteristics of a variety of material factors , but also reflects the non-linear characteristics of the materials in the structure .
