CALCULATION METHOD AND ANALYSIS OF BEARING CAPACITY OF FRP REBARS CONCRETE BEAM

摘要

The mechanical properties of FRP rebar and steel bar are very different, and the design of FRP rebar concrete beam structure could not totally follow the method of conventional steel concrete structure. The study based on the research of specimen of FRP (Fiber Reinforced Polymer) rebar concrete beam analyzes the failure mode of the FRP rebar concrete beam. As for the two destructive forms, tensile and compression failure, the formula of normal cross-section bearing capacity of FRP rebar concrete beam is deduced. ANSYS software has been used to get the numerical simulation of the deformative characteristic process of FRP rebar concrete beam. The results of test, numerical simulation and theoretical calculation are identical.
