| Summary: |
| Influence of cross sectional shape of reinforced concrete prismatic folded
plate structure, of span length L=20m, on internal forces and displacements was
analysed using finite strip method. The paper presents and comments obtained diagrams
of displacements, rotations, internal forces, moments and stresses. Selection of the
optimal cross-section can be made based on comparisons of these diagrams for different
shell "depth". By analysis of obtained diagrams it is concluded that too "shallow" cross
sections of prismatic folded plates should be avoided. Convenient fo rm of the cross
section is obtained by placing particular plates under such an angle to achieve
maximum similarity with the corresponding cylindrical shell. |
