Bridge Loads

Bridge Design - Standard Highway Loadings Type HA

Equivalent UDL to be used with Knife Edge Load (KEL)

TABLE 1
Loaded Length (m) Force, KN/m of Lane 
1 - 23 31.5
24.0 31.2
25.0 30.8
26.0 30.4
27.0 30
28.0 29.7
29.0 29.3
30.0 28.9
31.0 28.5
32.0 28.2
33.0 27.8
34.0 27.4
35.0 27.0
36.0 26.8
37.0 26.6
38.0 26.2
39.0 26.0
40.0 25.7

Type HA Loadings = UDL + KEL

Width of
Traffic Lane
Beam or Slab Decks Transverse Slabs
3m or less

Lane loading=Loading from Table 1 x w/3

Load/sq m = lane loadings x 1/3

KEL/m=40 KN 

 Over 3m

Lane Loading = Loading from Table 1

Load/sq m = Land Loading/W

KEL/M = 120KN/w KEL/m = 40KN

For Highway Bridges, Type HB Unit Loading , 1 unit = 12.50 KN. Allow 4 units HB Vehicle.
