Abstract

Based on the relaxation experiments of AFRP tendons for half a year,the variation regularities of the relaxation rate according to time of one kind of AFRP,FA11,are studied.The results indicate that the relaxation of AFRP is obvious,and the relaxation rate linearly depends on time and is in direct ratio with tension control stress.
