![]() It is also important to consider accidental actions on the bridge especially vehicle collision on the substructure of the bridge. However, there are non-traffic actions that are possible on footbridges such as thermal action, wind action, snow action, indirect actions such as support settlement, etc. This force is usually sufficient to ensure the horizontal longitudinal stability of the bridge. ![]() This horizontal force does not coexist with the concentrated load, and acts along the bridge deck axis at the pavement level on square surface of sides 0.1 m. This load is not to be combined with other variable non-traffic load.įor horizontal forces, a horizontal force acts simultaneously with the corresponding vertical load whose characteristic value is equal to 10% of the total load corresponding to the uniformly distributed load. Q fk = 2.5 kN/m 2 ≤ 120/(L + 30) ≤ 5.0 kN/m 2įor local assessment, a concentrated load of 10 kN is is considered to be acting on a square surface of sides 0.1 m. ![]() ![]() However, when there is no such risk of dense crowd action, the load on the pedestrian bridge is given by This value is synonymous with continuous dense crowd action which is given by Load Model 4 of road bridges. However, when a road bridge is supporting a footway, a UDL value of 5.0 kN/m 2 is recommended by the code for that section. The effect of crowd action on a footbridge is represented by a uniformly distributed load which depends on the loaded length of the footbridge. (3) One or more, mutually exclusive standard vehicles to be taken into account when maintenance or emergency vehicles are expected to cross the footbridge itself (not applicable in this post). (2) One concentrated load representing the effect of maintenance load, (1) A uniformly distributed load representing static effect of a dense crowd, There are three mutually exclusive envisaged vertical load models for footbridges (5.3.1(2) EN 1991-2:2003) ![]()
