초록

본 연구의 목적은 1축압축을 받는 판 및 보강판의 최종강도추정을 위한 경험식의 도출에 있다. 이를 위해 다른 연구자에 의해 수행된 많은 실험결과를 정리 하였고, 식의 도출에 있어서 넓은 범위의 판의 치수에 대한 이들 실험결과의 유용성을 확인하였다. 또한, 필요한 치수범위에 있어서 편면보강재를 가진 보강판에 대한 압축 최종강도 실험을 추가적으로 수행하였다. 본 실험과 기존의 실험결과를 바탕으로 최소자승법에 의해 보다 더 유용한 경험식을 도출하였다.

The aim of this study is to derive an empirical formula for predicting ultimate strength of plates and stiffened plates subjected to uniaxial compression. The test data of ultimate compressive strength for unstiffened and stiffened plates previously obtained by others have been collected. Many test data are necessary so that the derived formula will be available in wide range of plate dimensions. Additional collapse tests for a plate specimen with one flat bar stiffener, varying dimensions of plate and stiffener were performed in this study. On the basis of the present and previous experimental data, a more useful empirical formula than the existing ones was derived by applying the least square method.
