摘要
采用拉拔试验研究相同直径GFRP筋和钢筋与混凝土的粘结性能,比较冻融循环前后的粘结性能,并分析冻融循环条件、筋材种类等因素对粘结性能的影响,试验结果表明冻融循环作用后的GFRP筋混凝土粘结强度高于钢筋混凝土粘结强度。
The paper presents a study on the bond behavior of concrete reinforced with GFRP bars bars reinforcing concrete. The pull-out test is used to study the bond behavior before and after thawing cycles. The influence of types of reinforced materials and conditions of freezing-thawing also studied. The conclusions indicate that the bond strength of GFRP of concrete reinforced with steel bars after freezing-thawing cycles. and steel freezing - cycles reinforcing concrete is higher than are that
