Railway Dynamic Factor Table by Element Table

Specify the dynamic factor to be applied due to the motion of traffic rail loads using the dynamic factor table.

From the Main Menu select Load > Moving Load > Railway Dynamic Factor Table by Element Table

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.

where h is the height of the cover.

Height Of the cover: Specify the height of the cover for the reduced dynamic effect consideration.

Dynamic Factor: Calculated Dynamic factor value based on the inputs.
