Modify SRC Material

 

 

 

Use this function to modify a part of the steel, concrete and rebar material property data entered during the creation of the analysis model or change the entered material property data suitable for design.

 

 

 

From the Main Menu select Design > Design > SRC Design > Modify SRC Material.

 

 

 

 

 

0-Check.jpg Material List

 

Display the steel, concrete and rebar material properties entered during the creation of the analysis model. Select the material property to be modified or changed with the mouse.

 

 

0-Check.jpg SRC Material Selection

 

Display the selected material property data separately classified by steel, concrete and rebar.

 

Steel Material Selection
The selected steel material data can be modified or changed.

The steel material data can be changed by using the steel material database built-in the program or by directly entering the data.

 

 

Using the steel material database

 

Select the design code and the material name with the mouse (refer to Note 1).

 

 

Direct entry by the user

 

Select 'None' in the Code field and enter the name of the material property in the Name field. Then, each field is activated so that the following material property data can be entered :

 

Es (Modulus of Elasticity): Modulus of elasticity of steel

 

Fu (Tensile Strength): Tensile strength of steel

 

Fy: Yield strength of the member which is thinner than or equal to 1.5'' (refer to Note 2)

 

 

Concrete Material Selection


Display the selected concrete material so that the material data can be modified or changed.

 

The concrete material data can be changed by using the concrete material database built-in the program or by directly entering the data.

 

 

Using concrete material database

 

Select the design code and the material name with the mouse (refer to Note 3).

 

The steel rebar and the concrete standards are identically displayed and can be changed by the user if necessary. In other words, the standards for the steel rebar and the concrete do not necessarily have to be the same.

 

 

Direct entry by the user

 

Select 'None' in the Code field and enter the name of the material property in the Name field. Then, each field is activated so that the following material property data can be entered :

 

Specified Compressive Strength (fck/fck): Design compressive cylinder strength of concrete

 

 

Reinforcement Selection (refer to Note 4)

 

Code: Select standard for rebar (refer to Note 5)

 

Main Rebar: Grade of main rebars

 

Sub-Rebar: Grade of sub-rebars (shear rebars)

 

Fyr: Yield strength of main rebars

 

Fys: Yield strength sub-rebars (shear rebars)

 

 

0-Modify.jpg : Update the previously defined material data.

 

0-Close.jpg : Do not enter the selection and close the dialog box.

 

 

Note 1
The steel material standards are classified by None, ASTM(S),CSA(s), BS(S), DIN(S), EN(S), JIS(S), GB(S), JGJ(S), KS(S), KS-Civil(S).

 

Note 2
The maximum thickness of a member determines the value of Fy.

 

Note 3
The concrete material standards are classified by None, ASTM(RC), CSA(RC), BS(RC), EN(RC), JIS(RC), GB(RC), GB-Civil(RC), KS(RC), KS-Civil(RC).

 

Note 4
When rebar data for SRC members have not been entered in the analysis model, the following values will apply:

 

Main Rebar = Grade 60 (Fyr = 60 ksi)

Sub-Rebar = Grade 60 (Fys = 60 ksi)

 

Note 5
The rebar material standards are classified by None, ASTM(RC), CSA(RC), BS(RC), EN(RC), JIS(RC), GB(RC), GB-Civil(RC), KS(RC), KS-Civil(RC).

 

Note 6
The applied values of the moduli of elasticity of the rebar are defined as follows:

 

The allowable stress design of the American SSRC(Structural Stability Research Council) (SSRC79) : 29,000 ksi

The SRC design of the Architectural Institute of Korea (AIK-SRC2K) : 2.1002-MSM-math01(X).jpg106 kg/cm2

 

Note 7
If "None" si selected in the Code field, user defined materials are used for design.
