축소모델의 지진모의실험을 위해서는 실물 실험체의 구조거동을 축소모델 실험체가 잘 모사하는지 상사성 확인이 필수적이다. 본 논문에서는 2층 RC 벽식구조 실험체의 반복 횡가력 실험을 통해 강도, 연성과 같은 전체거동과 휨, 전단, 들뜸과 같은 국부거동의 결과를 나타내었다. 인방보의 유무에 따른 3 : 5 실물 실험체와 1 : 7 축소모델 실험체를 비교 분석 하였으며, 1 : 7 축소모델 실험체가 실물 실험체의 전체거동과 국부거동에 대해서 대체로 잘 모사하고 있음을 확인하였다.
For earthquake simulation test it is essential to make sure the similitude in behaviors between the full scale prototype and the reduced scale model. This paper presents the test results obtained through the cyclic lateral-force test, on two-story RC wall subassemblages. A lower 2-story portion of the prototype structure was selected as subassemblages. The global behavior such as the strength and ductility, and the local behavior such as flexural, shear and uplift deformation were measured. The test results of the 3 : 5 scale specimens representing the prototype were compared with those of 1 : 7 scale models. Two types of subassemblages were used: One with lintel beams and one without lintel beams. The comparison shows that 1 : 7 scale model simulated in general successfully the global and local behaviors of the prototype.
