Create an analysis case. Add a new analysis case, or modify, copy, delete an existing analysis case. The input window for analysis case creation is as follows:

General

[Name] : Input the analysis model name.

[Description] : Input the description for the analysis model.

General Setting

[Ground Material Set] : Select the modeled stratum to be used for analysis.

[Depth No. of Bed Rock] : Select the stratum number corresponding to the bedrock.

Control Motion Input

[Outcropping(2E)] : Set the ground acceleration as an outcrop state.

[Within(E+F)] : Set the ground acceleration as the ground response.

[Depth No.] : Select the control point for the earthquake wave input stratum.

[Ground Acceleration Function] : Select the input earthquake acceleration time varying load.

Water Level

[No. of Water Level] : Stratum ID inputted in Ground Material can be selected, and it calculates assuming that the water level exists from the selected stratum.

Analysis

[Cut-off Frequency] : Set the maximum frequency range for frequency analysis.

[Frequency Step (for Transfer function)] : Set the calculation frequency spacing for transfer function analysis.

[Maximum Number of Iteration] : Input the maximum iterative calculations to find the equivalent linear material property value.

[Tolerance] : Input the tolerance for the shear modulus and damping ratio used to find the equivalent linear material property value through iterative calculations.

[Effective strain coefficient] : Input the coefficient needed to calculate the effective shear strain from the maximum shear strain.

Response spectrum

[Damping] : Input the damping ratio to calculate the response spectrum.
