Dams & Dikes

Dams and dikes are complex structures whose analysis requires the advanced functionality of a finite element analysis software package that can carry out complex analyses with ease.

Proven in this sector as the right choice for complex structural analysis 

DIANA’s comprehensive material and analysis functions make it the ideal choice for complex structure analysis. Within one software package and in one analysis, you can carry out complicated concrete analyses in conjunction with geotechnical and dynamic functionality to ensure that you are designing a safe, cost-effective and, in today’s terms, “green” structure.

The right track history

Because of the importance of such critical structures, you need to be sure that you are using a proven software for the job.
DIANA provides you with the ability to ensure that you are following in the footsteps of many successful projects around the world. As a designer of sophisticated structures, many factors need to be taken into account:

  • Construction phases including nonlinear material behavior over time, and ambient/time/temperature dependent material behavior.
  • The interaction of the structure between the reservoir, the ground and its foundation against the whole body of the dam
  • Forces incumbent on the dam during or after – eg. earthquake, and other coupled phenomena
