| Abstract: | In order to improve the ductile behavior of reinforced fibrous exterior beam-column joints and evaluate the development of damage and fracture,the research of full-scale specimen under low cyclic loading is carried out.The strength,damage performance and energy distribution are obtained according to the experimental result.Also the fracture mechanism and procedure are further explored.It is shown that the utilization of fiber reinforced concrete and optimization of the density of stir-up can enhance both the ductility and strength of the joint. |
