Three Dimensional Finite Element Analysis of Structures under Wind Loads
풍하중을 받는 구조물의 3차원 유한요소해석
Abstract
This paper compares conventional beam analyses with exact three dimensional plate analyses through numerical examples with plates under wind loads in order to study the disadvantages of conventional simplified beam analyses of wind-loaded structures, Bending moments and principal stresses from beam analyses are good agreements with those from plate analyses but torsional moments are not. And it is possible to get result forces which are variant along width directions from plate analyses but not from beam analyses due to constant distributions of result forces along width directions. Therefore exact three dimensional plate analyses are required in the analyses of wind-loaded structures instead of conventional simplified beam analyses.
