Experimental Study on the Similitude in Flexure, Shear and Bond Behavior of Small-scale R.C. Beams

축소모델 철근콘크리트 보의 휨, 전단 및 정착거동에 관한 상사성 실험연구

The small-scale models have been utilized for the prediction of inelastic behavior of reinforced concrete structures for a long time. The parameters that affect the similitude between the model and the prototype are various. Among them, the effect of bond between the model reinforcement and the model concrete is one of the most important factors. The study reported herein is addressed to verifying this similitude in bond behavior. Another topic is the similitude in shear. The selected scales are 1/1, 1/5, 1/10 and 1/12. Two prototype specimens and three models were tested in addition to the associated material tests. The test results are compared from the viewpoint of similitude.
