i-concrete Applets

Java applets are an older solution for executing a programme within a web page.

The i-concrete site offers various types of applets, which aim to facilitate the understanding and modelling of the behaviour of concrete structures.

NEW: Starting in June 2025, it is now required to first sign in to i-concrete from a “normal” (non IE) browser, then again from Edge in Internet Explorer (IE) mode to use the Java applets

IMPORTANT: Please read these pages if you want to use the Java applets
