XFrame3d of course referred to 3d frameworks, but by now our flagship product can do so much more than that. Think for example of a calculation of 3d frameworks in steel and\u002For timber, concrete beam grids, slab foundation, flat plates supported by columns or walls, walls, shells, and so on.

Johan has developed a calculation method with which reinforcement in a plate or shell can be designed efficiently. He has also advised us to use hybrid quadrilateral elements because they enable us to determine an accurate shear force. Johan has supported us in the realization and implementation of this.\u003C\u002Fp>\n\u003Cp>In autumn there will be a publication in Cement by Prof. Johan Blaauwendraad about the calculation with such a hybrid plate\u002Fshell element as implemented by Struct4U.\u003C\u002Fp>\n\u003Cp>To be able to calculate quadrilateral elements we also had to incorporate another mesh-er. And that's what we did. That new meshing tool works really great and is also more intuitive.\u003C\u002Fp>\n\u003Cp>The longitudinal reinforcement and shear reinforcement are automatically designed for strength (ULS) and also for cracking (SLS).
