Use this function to modify a part of the steel material property data
entered during the creation of the analysis model or to change the entered
material property data pertaining to specific design requirements.
From the Main
Menu select Design > Steel Design Parameter > Modify Steel
Material.
From the Menu
tab of
the
Tree Menu select Design
> Steel Design Parameter > Modify Steel Material.
Use the following dialog box to enter the
data (refer to Note
1):
Modify Steel Material dialog box
Material List
Display the material properties of steel
entered during the creation of the analysis model. Select the material
to be modified or changed with the mouse.
Steel Material Selection
Display the selected material so that the
property data can be modified or changed.
The material property data can be changed
by using the material property database
in the program or by directly
entering the changed data.
Method for
using material property database
Select the material name and the code in which the relevant material is
defined, with the mouse.
Direct entry
by the user
Select 'None' in the Code field and enter the name of the material in the
Name field. Once these entries are made, all the material property data
fields are activated for data entry (refer to Note 2).
Modulus
of Elasticity (Es): Modulus of elasticity of steel
Poisson's
Ratio (Ps): Poisson's ratio of steel
Tensile
Strength (Fu): Tensile strength of steel
Yield Strength
(Fy)
Yield strength
of members with thicknesses thinner than 40mm (refer toNote 3)
Yield Strength
[t > 40mm] (Fy2)
Yield strength
for which the thickness of the members in use is thicker than 40mm (refer
to Note 3)
: Modify the relevant
material property data by replacing with the values entered by the user.
: Do not enter the values
or the selection and close the dialog box.
Note
1
When the Name, Es, Ws, Fy1 and Fy2 are not entered in the analysis model,
the following data are applied by default :
Name = A36
Es = 4.176+E9
lb/ft2 (29,000 ksi)
Ws = 490 lb/ft3
Fy1 = 250 lb/ft2 (36 ksi)
Fy2 = 250 lb/ft2
(36 ksi)
Note
2
The steel material standards are classified into None, ASTM(S),CSA(s),
BS(S), DIN(S), EN(S), JIS(S), GB(S), JGJ(S), KS(S), KS-Civil(S).
Note
3
The Fy-a, Fy-b, Fy-c and Fy-d values below represent the steel yield strengths
and are used to calculate the allowable stress (design strength) for each
stress component (compression, tension, bending and shear) during the
strength verification. The maximum thickness of a member determines the
application of Fy-a, Fy-b, Fy-c and Fy-d for the calculation of the allowable
stress (design stress). The heading, Fy-a, Fy-b, Fy-c and Fy-d (simply
expanded to demonstrate the variation) listed below do not necessarily
correspond to the heading in the dialog box.
