| Abstract: | Basalt fiber reinforced polymer tendon is a new type of advanced composite material.BFRP is of multiple advantages which include light weight,high strength,non-magnetic,high temperature and acid resistance.The mechanical performance and the relaxation loss of φ10 mm BFRP tendons are firstly tested.After that,the flexural behavior of three prestressed and one non-prestressed concrete beams are tested.As a result,the loading process and failure modes,the development of plane-section assumption,the characteristic load,relationship of load-deflection,as well as ductility coefficient are obtained.On the basis of the experimental data,deflection limitation of concrete flexural member reinforced with BFRP tendons are given,flexural behavior between prestressed and non-prestressed BFRP reinforced concrete beams is compared and analyzed.The results can be used for further study on concrete flexural member reinforced with BFRP tendons. |
