In particular, the webs and flanges of beams, simple walls, brackets, bracing beams and joints of frames are investigated. By this means, the majority of design cases are already covered. In reality, all structural components are three-dimensional. Here, however, components are considered either directly as two-dimensional plate elements (i. e. the plane stress condition with no variation of stress over the thickness of the element) or they are subdivided into several plates. Since two-dimensional structural elements are statically redundant, it is pOSSible for a particular loading to be in equilibrium with many (theoretically an infinite number of) stress states. If the lower bound method of the theory of plasticity is employed, then an admissible stress field or any combination of such stress fields may be selected. In chapter 4 it is shown that this method is suitable for the design of reinforced concrete structures, and the consequence of the choice of the final struc | | 出版日期 | Textbook 1997 | | 关键词 | Fundament; Torsion; beam; concrete; development; prestressed concrete; reinforced concrete; structure; theor | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-0348-9047-2 | | isbn_softcover | 978-3-0348-9885-0 | | isbn_ebook | 978-3-0348-9047-2 | | copyright | Birkhäuser Verlag 1997 |
