KSCE-LSD12(S) : Apply the material strength of structural steel specified in the Road Bridge Design Code (Limit State Design Method) - V810-541.
KS10-Civil(S) : Considering the Additional Steel Grades in the Korean Road Bridge Design Standards (2010)
KS08-Civil(S) : Korean Industrial Standards, SI unit system applied
KS-Civil(S) : Applying the Allowable Stress of Structural Steel specified in the Korean Road Bridge Design Standards (Ministry of Land, Infrastructure and Transport)
KS08(S) : Korean Industrial Standards, SI unit system applied
KS(S) : Applying the Allowable Stress of Structural Steel specified in the Korean Industrial Standards, Steel Structural Calculation Standards (Korea Institute of Civil Engineering and Building Technology).
Differences between KS(S)and KS-Civil(S)
The allowable stress of structural steel varies depending on the thickness, and even for the same steel grade, the application method differs according to the design standards. In the Steel Structural Design Standards (AIK-ADS), the thickness of the steel is divided into two regions, while in the Road Bridge Design Standards (KSCE-ADS), it is divided into 2-3 regions based on thickness.
Differences between KS-Civil(S) and KS08-Civil(S)
KS-Civil(S) is a material defined in the CGS (Centimeter-Gram-Second) unit system, while KS08-Civil(S) is a material defined in the SI (International System of Units) unit system.
The meaing of KS08
The standard information in the KS (Korean Standard) criteria continues to evolve. New steel grades are added, and the information regarding existing steel grades is also updated. KS08 indicates that it reflects the content of the KS criteria revised until 2008.

Differences between KS(RC) and KS-Civil(RC)
Taking into account the difference in unit weight according to the design conventions of architecture and civil engineering engineers, KS(RC) applies a unit weight of 2.3 ton/m³ (except for self-weight calculations, where it is 2.4 ton/m³), while KS-Civil(RC) applies a unit weight of 2.5 ton/m³.
Differences between KS-Civil(RC) and KS01-Civil(RC)
KS-Civil(RC) is defined in the CGS (Centimeter-Gram-Second) unit system, while KS08-Civil(RC) is defined in the SI (International System of Units) unit system. The design standard values of the materials have been adjusted to reflect the change in unit system in the design criteria.
The meaning of KS01
The standard information in the KS (Korean Standard) criteria continues to evolve. New steel grades are added, and the information regarding existing steel grades is also updated. KS01 indicates that it reflects the content of the KS criteria revised until 2001.

DB : Select the types of concrete registered in the standard codes of each country.
When Type = 'SRC'
Enter the material properties for steel and concrete in the respective input fields using the same method as Type = 'Steel' and 'Concrete'.
When Type = 'User Defined'
This option is used when the material type is not 'Steel', 'RC', or 'SRC', or when the user wants to input the material data directly. It also allows for entering material properties for orthotropic materials based on the element coordinate system. However, materials defined as 'User Defined' are not applicable in the design functions.
Modulus of Elasticity
Poisson's Ratio : The Poisson's ratio is used in the calculation of the shear modulus for elasticity.
Thermal Coefficient : Coefficient of thermal expansion, Coefficient of thermal expansion is used in thermal stress analysis.
Celsius : Celsius temperature scale
Fahr. : Fahrenheit temperature scale
Shear Modulus : Shear modulus (Local-xy, Local-xz, Local-yz), Shear modulus = Elastic modulus / (2 x (1 + Poisson's ratio)).
Type of Material = For isotropic materials, the shear modulus is automatically calculated using the aforementioned formula.
Type of Material = For orthotropic materials, the user-inputted shear modulus values are used.
Weight Dinsity : Unit weight (or specific weight)
It is used in the analysis process to calculate self-weight and mass.
Use Mass Density : Mass per unit volume
When "Use Mass Density" is checked, the Mass Density is calculated using the gravitational acceleration (g) provided in the database. When "check off," the Mass Density is calculated using the gravitational acceleration (g) specified in the Structure Type. This mass is independent of the Dead Load and is only applied during the eigenvalue analysis.
