Modify Concrete Material
Use this function to modify a part of the steel rebar and concrete material property data, entered during the creation of the analysis model, or to change the material property data. Modifications that are made here will not affect the analysis results, but will only be used for automatic design and strength verification.
From the Main Menu select Rating > Bridge Rating Design > CS454/19 > PSC Bridge > Modify Concrete Material
The following dialog box is used to enter the data:
Material
List
Display the steel rebar and concrete material properties entered during the creation of the analysis model. Select the material to be modified or changed.
Concrete
Material Selection
Display the selected material properties and modify/change the material property data.
The material property data can be changed by using the material property database built-in the program or by directly entering the changed data.
Procedure
for using the material property database
Select the relevant code and the material name with the mouse.
The reinforcing steel bar standards are specified similar to the concrete standards and may be changed by the user if necessary. That is, the concrete and rebar standards need not be the same.
Direct entry by the user
Select 'None' in the Code field and enter the name of the material
to be used in the Name field. Then, each data field is activated
and the following material property data can be entered :
Specified Compressive Strength (f'c/fck): Design compressive cylinder strength of concrete
Rebar
Selection
Code: Select reinforcing steel standards
Grade of Main Rebar: Grade of main rebar
Grade of Sub-Rebar: Grade of sub-rebar (stirrups & ties)
Fy: Yield strength of main rebar
Fys: Yield strength of sub-rebar
: Modify the material property data as defined by the user.
:
Do not enter the selection and close the dialog box.
