Function
- 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.
Call
From the main menu, select [Design] tab > [Type : Steel Composite Design] > [Design Input Data] group > [Design Parameters] > [Deck Overhang Loads]
Input
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.
The program uses F to calculate uniformly distributed lateral bracket force Fl.
where,
Fl = F tan α
Ml = FlLb2/12
Concentrated Force : Enter the unfactored concentrated force, P. The program considers load factor of before composite dead load automatically.
The program uses P to calculate concentrated lateral bracket force Pl
where,
Pl = P tan α
Ml = FlLb/8
Eccentricity of Overhang Loads : Enter the eccentricity of deck overhang loads, e.
The program uses e to calculate α, i.e. α = tan-1(e/D). D is the total web depth.
