Cofra5 – designing composite floors made easy

CLICK ON LINKS BELOW AT BOTTOM OF PAGE

Arval, the ArcelorMittal brand specialised in innovative steel solutions for façades, roofs and, in particular, composite floors, is pleased to announce the release of Cofra5.

Cofra5 is a new, web-based, design software to facilitate the design of lightweight composite floor solutions. Cofra5 makes it easy to propose alternatives to traditional floor structures quickly and reliably, thereby allowing the evaluation of the technical feasibility of such alternatives in the early stages of a project.

Simplify the basic engineering of composite floor systems

In the search for the most appropriate technical and economical solution for their client’s structural concept, engineers need to compare a wide range of construction alternatives. The number of alternatives that can be considered is limited by the effort required to assess each design.

Cofra5 is an easy-to-use tool to check the technical feasibility of a composite floor design – rapidly and completely. Cofra5 allows more options to be assessed early in the project.

Calculation according EC 4 as additional service to our product range

Cofra5 covers both the static analysis of the construction stage of the project as well as the final behaviour of the composite system in use. The software is based on the demonstrated performance of ArcelorMittal Arval’s product range of composite floor sheets (Cofrastra and Cofraplus) and takes into account the specific national design parameters wherever general Eurocode design rules are accepted.

The software can also work with specific German DIN regulations and allows the user to set up other criteria individually, such as crack limitation or redistribution of the hogging moment. Defined for single or irregular multi-span systems, the Cofra5 software can apply complex, punctual, linear and mobile loads and so can reproduce all common scenarios.


Ease-of-use and web-access are key to user-friendliness

The simple user-interface, with choice of language, has a simple input mask and delivers the calculation results either in a summary report or as full documentation both in pdf-format.

By being web-based the software guarantees compatibility with any IT-system and ensures that the latest version is always available for use. Each subscriber’s account is password protected and users manage their own project data and store project calculations.
