Braking Page EC

The braking load is calculated according to EC 1991-2, 4.4.

The load is considered to be applied uniformly distributed in longitudinal direction along the roadway axis acting at the finished roadway level and in case of grillage modeling distributed proportionally to all applicable main girders.

Setting	Description
Total braking load	Braking force according to EC 1991-2, 4.4.1 expression (4.6) Q_lk = 0.6×α_Q1×(2×Q_1k) + 0.10×α_q1×q_1k×w_l×L as a fraction of the total vertical load on notional lane 1 (see traffic load definition).
Height of application	Distance between the cross-section slab surface and the level of the finished roadway.
Total line load	Intensity of the line load deriving from dividing the total braking force over the length of the bridge as defined in Superstructure > Spans. Note: This value is calculated automatically and cannot be changed directly but only by adapting the "total braking load".
