AVD (Acceleration-Velocity-Displacement)

Navigation: User Interface Overview > Charts >

The AVD chart plots the Acceleration-Velocity-Displacement histories of one or multiple recorded ground motions on the same chart. Below are the description of the AVD Ribbon along with screenshots of one and three components of a record AVD charts. Note that the AVD charts are shown only if the users have the record histories is available in the GM Library Database. To display the AVD histories, the record acceleration files should be available in the GMLibrary folder.

Chart

Show/hide chart general features:

•Legend: show/hide the chart series legend

•Records: show/hide individual records (components & triplets)

•X Log: switch the X-axis scale between Linear and Logarithmic

•Y Log: switch the Y-axis scale between Linear and Logarithmic

•X Grid: show/hide grids on the X coordinates (parallel to Y-axis)

•Y Grid: show/hide grids on the Y coordinates (parallel to X-axis)

•Norm X-Axis: switch the X-axis normalization on/off (normalizes X-axis such that maximum value is 1.0)

•Norm Y-Axis: switch the Y-axis normalization on/off (normalizes Y-axis such that maximum value is 1.0)

•Freeze X-Axis: freeze X-axis scale to its current range (min,max)

•Freeze X-Axis: freeze Y-axis scale to its current range (min,max)

Components

Show/hide a specific record component in the chart:

•H1 Comp: show/hide 1st Horizontal Component

•H2 Comp: show/hide 2nd Horizontal Component

•V Comp: show/hide Vertical Component

Peaks

Show/hide the following chart annotations:

•Maximum: display the maximum value of the acceleration, velocity and displacement charts

•Minimum: display the minimum value of the acceleration, velocity and displacement charts

•Absolute maximum: display the absolute maximum value of the acceleration, velocity and displacement charts

Copy Data

Users may select the output chart of interest and have the ability to perform the following:

•Copy Metadata, copies the record view record data, including header and footers of the data, which makes it easy to create record tables in MS Excel or Word.

•Copy Chart Data, copies the chart series data which can be exported to create tables in MS Excel or Word.

•Copy Chart Image, take a screenshot of the selected chart
