Change Element Dependent Material Property

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.

From the Main Menu select Properties > Time Dependent Material > Change Property.

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
