Foundation elements

A new tool: Strut3D, has been incorporated in the 2013.e version of CYPECAD, Metal 3D and Foundation elements. Strut 3D checks foundation pile caps using a general calculation method in which the D regions of the reinforcement are analysed using a strut and tie model, in order to guarantee the structural requirements are met in accordance with the standards. The strut and tie model used has been previously validated by a linear finite element analysis.

Additionally, Strut3D provides a graphical output of the results, allowing users to consult them on screen and in the detailed verification reports, which indicate whether or not they comply with the standards. The information provided is of great importance, as it is this information which will be used by the project designer when deciding on and justifying the design.

Strut3D is the result of a development project developed by CYPE with the collaboration of the 'Instituto de Ciencia y Tecnología del Hormigón' (ICITECH) of the 'Universidad Politécnica de Valencia' (UPV), financed by the 'Centro para el Desarrollo Tecnológico Industrial (CDTI) and co-financed by the European Regional Development Fund (ERDF).

Therefore, Strut3D is a breakthrough compared to other products currently in the market, because it verifies and justifies compliance with the design standards based on an optimised strut and tie model in a simple and intuitive manner for its users.

To access Strut3D in CYPECAD or Metal 3D, users must have a license providing access to version 2013.e or higher in either of these programs, and their Pile caps module. To access Strut3D in the Foundation elements program, users only require the program with version 2013.e or greater.

The first version of Strut3D currently only considers the Spanish EHE-08 concrete design code. More concrete design codes will be implemented in upcoming program updates.

More information on this CYPE program tool will be available shortly.
