초록
국외 수입에 의존하고 있는 띠형 강판 보강재를 대체할 수 있는 새로운 강(steel) 보강재로서, 강판과 지지부재를 결합한 새로운 형태의 보강재를 고안하였다. 개발 보강재는 폭
A steel strip reinforcement for the reinforced earth structures was recently developed to substitute the existing ribbed steel strip reinforcement. The developed reinforcement consists of the punched steel strip having dimension of 65mm width and 4.5mm thickness and the transverse steel bar for increasing bearing resistance. The punched steel strip has holes of 11mm diameter in every 50cm spacing with 2mm rising around perimeter of the holes. A series of shear friction tests and pull-out tests were carried out to evaluate the friction properties of the developed reinforcement. The results of these tests show that pull-out resistance of the developed reinforcement was significantly increased when the transverse steel bars are installed in the punched steel strip.
