PLPAK for academics
The PLPAK is a rigorous structural analysis software that has an interactive interface, BIM (Building Information Model) design and capabilities of real geometry modeling. These capabilities of the PLPAK present it as a useful tool for academics to demonstrate the simple structural analysis applications to students.
This page has some examples that may be useful to present the simple structural engineering applications to students in an interactive approach.
For academics who wish to know more about the PLPAK educational prospects, you may contact our services team at services@be4e.com.

Beams: Negative moments in simple beams
This example is provided to demonstrate the code provisions for top reinforcement above supports in simple spans. The model presented herein proves that there is a small value for negative moment that appears above the support even in the case of simple supports.
