Abstract:

FRP fural resin concrete which has extensive application prospect is a kind of anticorrosive new engineering material.Although its stronger in compression than cementitious concrete，its tension behavior is weak，the reinforcement of polymer concrete beams in the tension zone with pultruded profiles made of resin and glass fibers are a good compromise between strength and stiffness.In this paper，firstly the experience has performed about the bending and creep characteristic of nonFRP reinforced furan resin concrete beam and FRP reinforced furan concrete beam，the creep  curves are gained of the beams under different loads by fourpoint bending tests method，analysis is carried on the viscoelasticity nature，the result shows that FRP not only enhances the furan resin concrete beams initial stiffness and strength，but also obviously reduces the creep strain of the beam.Secondly the creep model variables are determined through the least square method，the bending creep power law model are separately built of nonFRP reinforced furan resin concrete beam and FRP reinforced furan concrete beam，which is the basis of estimation of materials long term mechanics performance，and also has important project practical value to the FRP furan resin concrete structure design.
