초록

공동주택의 구조형식이 기둥식 구조로 이행되면서 경량벽체의 수요가 증가하고 있다. 경량벽체는 구조적 안전을 위해 소정의 내충격성을 확보할 필요가 있다. 본 연구에서는 질량과 형상이 다른 경질 충격체 7종류와 일상적으로 벽체에 충격하중을 가하는 단단한 물체 5종류를 대상으로 하중해석 실험을 실시하였다. 충격에너지가 같아도 추의 질량이 다르면 하중의 크기가 최대 2배 이상 차이가 난다는 것을 실험적으로 규명하였다. 또한 경질 충격체의 하중과 실제 물체의 하중을 비교 분석하여 경량벽체의 재료설계를 위한 기초적 자료로서 제시하였다.

The demand for the lightweight wall has increased as the structure of the multi-unit dwelling has shift to the rahmen structure. The lightweight wall is required to secure certain degree of shock resistance for the structural safety. The study performed the load analysis test for 7 small hard bodies with different masses and shapes and 5 hard materials which applied the impact load on the wall. It was found out from the experiment that different pendulum weight doubled the load maximum even though the shock energy was the same. In addition, the study compared and analyzed the weight of materials and the load of small hard bodies to propose fundamental data for the material design of the lightweight wall.
