Enhancements in ELPLA 9.0


  Design for punching¬†
  It is possible to design the floor slab or raft foundation for punching due to concentrated loads and reactions from columns, piles or supports. The design for punching is carried out according to 4 different codes: ACI, DIN 1054, EC2 and ECP.

  Flexibility coefficients for interior nodes
 

For rigid and elastic rafts, it is convenient to determine the flexibility coefficient of interior node at the characteristic point of the loaded area on that node. While for flexible foundation, it is real to determine the flexibility coefficient of interior node at that node.

Now it is possible to determine the flexibility coefficient of the interior node due to a uniform load at that node Figure B-3

- at the characteristic point of the loaded area, where rigid settlement equal to flexible settlement.
- at the midpoint of the loaded area, where maximum settlement occurs.
- at the interior node on the loaded area.
  Flexibility coefficients for exterior nodes
  Earlier versions of ELPLA determine flexibility coefficients for both interior and exterior nodes by assuming uniform loaded areas on these nodes. This assumption uses the principle of superposition for determining the flexibility coefficients. Now it is possible to convert the loaded areas on exterior nodes to point loads, Figure B-3. By this way the program doesn't need to use the principle of superposition in the analysis, making it much faster than the old analysis. The new way of analysis is consequently faster and more efficient for problems that contain a large finite element mesh.
