Function
When the Time Dependent Material Property of structural materials is defined by CEB-FIP, the geometric shape dimension (h) is revised here. The dimension (h) is applied to automatically calculate the time dependent property of the elements that used the defined material. When a number of elements of an identical material property have different geometric shape dimensions, the dimensions can be entered for each element, overwriting the geometric shape dimensions defined in the Time Dependent Material (Creep/Shrinkage).
This function is not applicable for the Composite Section for Construction Stage, and the user needs to directly enter the Notational Size of Member (h) for each Part in Composite Section for Construction Stage.
Call
From the Main Menu select [Properties] tab > [Material Properties] group > [Change Property]
Input
Option
Add/Replace : Add or replace the geometric shape dimension (h).
Delete : Delete the geometric shape dimension (h).
Element Dependent Material
Notational Size of Member : Element geometric shape dimension
Input : Specify the user-defined h
The formula is h=2*Ac/u in CEB-FIP Code
Ac : Section Area
u : Perimeter in contact with atmosphere
Select a standard applicable for calculating h.
Auto Calculate : The Program auto-calculates the values using the section properties
Note
1. The 'h' dimension revised here supersedes the value entered in Time Dependent Material (Creep/Shrinkage).
2. In case the Composite Section for Construction Stage is used, 'h' for each Part needs to be entered in Composite Section for Construction Stage.
Volume Surface Ratio
Input : Specify the user-defined v/s
The formula is v/s = Volume/Structure in
(ACI, PCA, Combined(ACI&PCA)) Code
Select a standard applicable for calculating v/s.
v : Volume
s : Surface area
