Loads
Enter the load cases and loads required to analyze a RC slab bridge. Load cases and combinations are automatically generated in an auto-generated model.
Fig. R.C. Slab Bridge Wizard Loads dialog box
Load Combinations
Factored
Factored load combinations are auto-generated.
Unfactored
Service load combinations are auto-generated.
In V 6.3.0 we can specify loads by "KRTA-BRG2K, AASHTO-Std2K, AASHTO-LRFD02, IRC: 6-2000 and Taiwan", and options are activated depending upon each country code.
Define Moving Load Code
Select the moving load code of a country.
Self Weight
Self-weight.
Pavement
Weight of pavement (pressure load).
Thickness
Pavement thickness.
Weight Density
Weight density of pavement.
Barrier
Barrier load (pressure load).
Self-Weight
Self-weight of barrier per unit length.
Additional Load
Additional loads such as noise barrier, guard rails, etc.
The linearly distributed loads entered for Barrier and Median Strip are divided by the widths entered in the Transverse tab and applied as pressure loads.
Median Strip
Self-weight of the median strip (pressure load).
Side Walk
Superimposed weight of sidewalk.
Thickness
Sidewalk thickness.
Self-Weight
Superimposed weight of sidewalk per unit volume.
Crowd Load
Human occupancy load.
Live Load
Bridge live load (It needs to be adjusted by comparing with AASHTO).
Class of Loading
Bridge live load grade, HS, HL, etc.
Eccentricity
Reference axis when the live load is applied eccentrically.
Settlement
Negative value
When Settlement is entered, the settlements by the locations of the auto-generated support settlement group are automatically analyzed.
Temperature
Temperature difference between the top and bottom surfaces of the slab
Wind Load
Wind load acting on the bridge and noise barrier
W
Lateral wind load acting on the bridge and noise barrier
T
Moment due to the lateral wind load acting on the noise barrier.
