Abstract

Polyurethane Fly Ash (PUFA) is a new type of environmentally friendly material, with high strength, light weight, easiness of construction, and many other advantages.In this paper, according to the ductility design method, PUFA is bonded to the surface of the existing reinforced concrete bridge pier reinforcement to improve the aseismic capability of bridge pier. Through experiments and numerical simulation analysis, the article will evaluate and analyze the seismic resistance of PUFA. Several experiment samples are made out and tested in the lab. The relevant data is collected and analyzed. At the same time, using finite element analysis software OpenSees, the numerical simulation analysis of the test process are carried out, the numerical simulation results are in good agreement with the test results. Test and numerical simulation results show that axial compression ratio increases the ductility of the structure after the reinforcement of PUFA materials and after using PUFA, the maximum bearing capacity and elastic stiffness of the RC bridge pier have been improved.
