Free Field Analysis(Starting)

 

Overview

IMG_C_ICON_DOT.gif1D Ground Response Analysis, also called Site Response Analysis, is a program used to analyze the in-situ response of the ground for earthquake inputs before excavation or construction.

Methodology

First set the project and then input the strata information and material properties, dynamic material property function and ground acceleration function onto the model. Later, create an analysis case and conduct the analysis for result analysis.

 

File

Set the basic information of the project. Because the analysis results are affected by the values set in Project Setting, the settings need to be accurately set before analysis. It is best if the Project settings are pre-set when starting a new project, but it is fine if the settings are changed during modeling.

 

       

Set the unit system applied in the project. Click the [Unit Convert] button to set a different unit system. The time unit settings are not changed.

Return to the immediate previous state using undo, or use redo to return to the state before the command execution.
