The program ELPLA is a part of the program group GEOTEC. The original program ELPLA 4.0 was developed firstly under the operating system MS-DOS and then it was revised for the operating system MS Windows 95 in order to use the possibilities of the user interface offered in it. The program runs also under Windows XP/ Vista / 7.

ELPLA has a significant enhancement. The new features and enhancements are the result of feedbacks from users over the last years. The major enhancement in Version 9.2 is the ability to carry out a consolidation analysis beside elastic settlement analysis using the different calculation methods that are available in ELPLA. ELPLA also uses different types of finite elements, allowing the user to analyze any irregular shape of slabs with arc boundaries. Many improvements have been carried out in the generation of the flexibility matrix to allow the user solving large size problems faster.

The most important enhancements in ELPLA are explained in the next paragraphs.

GEOTEC Office Applications with Multilingual User Interface

The new English-language versions of GEOTEC Office applications with Multilingual User Interface (MUI) are now available. The Multilingual User Interface Pack is a set of language XML resource files that can be added to the English version of GEOTEC Office applications. MUI Pack allows the user interface language to be changed according to the preferences of individual users to one of the available supported languages. MUI Pack provides a single version of GEOTEC Office applications to which users can add one or more MUI Packs providing localized user interface and help files. Now, three languages are already available in ELPLA 9.1; English, German and Arabic.

The major benefits of the new MUI Pack are:

- Allows user interface switching between languages

- Easy to update with new languages

- Language-specific updates do not affect all languages

- Languages are XML based resources that make it easier to users to add their own languages.

 

Two-Dimensional Frame Problems

  The analysis of Two-Dimensional frame problems is now available in ELPLA.

 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

- 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.
