The PLPAK for You!

We are proud to introduce our main product the PLPAK. The PLPAK is a software tool for structural analysis of slabs that is based on the boundary element analysis of the shear-deformable plates. The PLPAK introduces a new era to more versatile user interaction with structural analysis. It provides advanced numerical methods for structural analysis of plates with a wide range of multidisciplinary applications. ( Check out our ACI (American Concrete International) paper regarding the PLPAK : "ACI PLPAK")

More About the PLPAK Features

The tool uses the boundary element analysis of the shear-deformable plates. From a simple CAD file to complex models of slabs (with the possibility of adding drop panels) and foundations. The PLPAK facilitates structural modelling and processes whole model creation in a matter of minutes. Harness this powerful tool, which uses the most thorough computation engine in producing results that were never thought achievable! Products of the BE4E solve structural systems using primarily the boundary element method. The earliest of these products was the PLPAK. Motivated by the accurate analysis procedures, several new products were created to serve for a wider range of structural analysis. This includes PLDesign for slab and beam design, and EHSPAK for advanced soil modeling (elastic-half space analysis). Check the features and the documentation from the links below!
