Mixte Verif
Software for design of composite road and railway bridges
Mixte Verif is an advanced software application for the design according to Eurocodes of composite road and railway bridges.
Mixte Verif allows the design of a composite bridge with I or box section. The internal forces under reglementary loads for the most unfavorable girder, calculated by any structural analysis software, are the data input of the software. Mixte Verif provides the capability to perform the calculation of internal forces for particular loads as shrinkage and temperature or other.
Mixte Verif defines automatically, all the reglementary combinations (SLS, ULS), calculates stresses and realizes all the Eurocode verifications. The verifications report is automatically generated.
Mixte Verif is developed and owned by Computer Control Systems S.A. (CCS).
Mixte Verif is the result of the high level of expertise and experience of CCS engineers in the composite bridges domain. CCS software is being used by organizations such as the design department of the French railways (SNCF), Design Offices, and Construction Companies such as Eiffage Métal and Baudin Chateauneuf.
General:
