Abstract

That main purpose of this paper is to clarify the effects of geometrically initial imperfection on the buckling characteristics of the pin-jointed single-layer lattice domes with triangular network. Additionally, this study is to get the data that is to formulate the general buckling-strength equation taking geometrically initial imperfection into consideration. Analysis is undertaken by using the frame analysis method which is based on the finite element method dealing with geometrically nonlinear problem.

본 연구의 목적은 삼각형네트워크를 갖는 핀접합 단층래티스돔이 형상초기부정을 가질 경우 하중상태에 따라 좌굴특성에 미치는 영향을 검토하는 것이다. 또한 형상초기부정을 고려하는 단층래티스돔의 일반화 좌굴내력식의 개발을 위한 기초자료를 수집하는데 있다. 해석은 유한요소법에 의한 이산화해석법을 이용했다.
