Mixte Verif is an advanced software application developed by Computer Control Systems (CCS) for the design of composite road and railway bridges according to Eurocodes. It allows the design of bridges with I or box sections and performs all necessary verifications like stresses, combinations, and reports. CCS has extensive experience in composite bridge design through projects with organizations like SNCF and the development of other bridge software solutions. Mixte Verif is the result of CCS's expertise in the domain of composite bridges.
