Function
- Define control parameters of deflection for serviceability check.
Note
Steel Serviceability Parameters are applied to beam and column members.
Call
From the Main Menu select [Design] tab > [Type : Steel Design] > [Design Input Data] group > [Design Parameters] > [Serviceability Parameters]
Input
Select a beam or column member from the Model View to enter the following parameters:
Option
Add/Replace : Add a new value or modify a predefined value.
Delete : Delete a predefined value.
Selection Type
Select all the members (All) or select the members by using By Selection.
[When Eurocode 02 is selected in design code]
Deflection Control for Beam
Enter the limiting deflection for beam members.
Deflection Control for Column
Enter the limiting deflection for column members.(h0= height of the building, h=story height)
Deflection Amplification Factor
Enter the Deflection Amplification Factor.
[When ACI318-14 (ACI318M-14) is selected in design code]
Deflection Control
Select the limits of deflection for short-term.
Long-Term Deflection Control
Select the limits of deflection for long-term.
- Live Load Reduction Factor : Enter the reflectance ratio of the live load at deflection calculation.
- Time-Dependent Factor : Select : Select the elapsed time after constructing. The factor is set automatically according to elapsed time, and User input is also possible.
Deflection Amplification Factor
Enter the Deflection Amplification Factor.
