CALDINTAV is a software for dynamic analysis of high-speed railway bridges developed by the Computational Mechanics Group, Civil Engineering School at the Technical University of Madrid.

The objective of this program is to provide the user a fast and simple tool to analyse dynamic effects not only on simply supported bridges but also on continuous bridges, covering a wide range of structures.

The main measures of dynamic performance for the design of the bridge may be obtained by CALDINTAV . For instance, dynamic impact factor, acceleration and displacement on the deck of the bridge.

Its GUI (Graphical User Interface) let the user use the program easily and dynamically.
