Dynamic Factor Table


The value of dynamic factor for the selected elements can be edited using the Dynamic factor table.


Determinant Length : If Auto is selected,the determinant length (Lphi) needs to be specified by the user.

Quality of track maintenance : The quality of the track can be specified in the table and the program calculates the value of Dynamic factor based on:


Reduced dynamic effect :In the case of arch bridges and concrete bridges of all types with a cover of more than 1,00 m, the value of dynamic factors may be reduced using the equation given below. Check the [ ] for the reduced dynamic effect to be applied.
