Calculation and evaluation of influence lines
The moving load calculation in Allplan Bridge allows for calculating the most unfavorable effects due to traffic. It is based on the theory of (related) influence lines allowing an easy and fast calculation.
First the influence lines are calculated by moving a unit force in the defined direction (Vertical, Transversal and Longitudinal) along the corresponding lanes. In the second step the evaluation of influence line is done by placing the load train such that the influence on the respective results becomes a maximum or minimum.
Final result of this is an envelope containing the most unfavorable effects. This lane related envelopes must be superimposed with other envelopes to represent the total maxima and minima for further design tasks.

- Design checks for prestressed and/or reinforced sections
- Considering the effects of creep, shrinkage and relaxation
