Deck Overhang Loads

Enter the parameters for calculation of deck overhang load. Lateral bending stress calculated from the deck overhang loads are applicable for top flange of tub section and top and bottom flange of I section. Lateral bending stress calculated from deck overhang loads is used in Constructibility check only.

From the Main Menu select Rating > Steel Bridge > Deck Overhang Loads

New for Civil 2015 (v1.1)

Firstly, select the members in the model and enter the following:

Deck Overhang Loads

Distributed Force: Enter the unfactored distributed force, F. The program considers load factor of before composite dead load automatically.

Note
The program uses F to calculate uniformly distributed lateral bracket force F_l.

where, F_l = F tan α

M_l = F_lL_b2/12

Concentrated Force: Enter the unfactored concentrated force, P. The program considers load factor of before composite dead load automatically.

Note
The program uses P to calculate concentrated lateral bracket force P_l

where, P_l = P tan α

M_l = F_lL_b/8

Eccentricity of Overhang Loads: Enter the eccentricity of deck overhang loads, e.

Note
The program uses e to calculate α, i.e. α = tan^-1(e/D). D is the total web depth.
