有限要素法によるコンクリート構造物の応力解析について Stress Analysis of Solid Concrete Structures by the Finite Element Method 西頭, 常彦 P(論文) In stress analyzing the massive concrete structures, for example, dam, abuttment, vessel, etc., conventionally it has been employed the beam theory. However, it is not suitable to estimate safety or utility life of solid structures. In such a case, generally we be driven by an impuls to know the stress distribution upon actual phenomena. Those stresses can be clarified by three dimensional analysis. That analysis can be performed speedy by using the Finite element method and digital computer. First of all, a concrete dam is divided into many tetrahedral elements. Deformation of each element is assumed to be a linear combination function (defined as the shape function). Then a potential energy II is calculated and treated with the Variational Principles in order to obtain the amount of deformation and the stress intensity. 1979 jpn departmental bulletin paper https://fukuyama-u.repo.nii.ac.jp/records/7596 AN00217655 福山大学工学部紀要 1 44 51 https://fukuyama-u.repo.nii.ac.jp/record/7596/files/KJ00005780906.pdf application/pdf 470.0 kB 1979-01-01
