GGU-VIBRATION: "Diagram" menu item

A diagram is shown on the output sheet containing the footing vibration velocity drawn against the distance to the endangered buildings. The format and appearance of this diagram can be edited in this menu item's dialog box, if the "Show diagram" check box is activated.

The position and size of the diagram can be defined or edited by means of the variables "X" and "Y", "Width" and "Height". The font size can be varied as required. The fastest way to modify the position or size of the diagram is to press [F11] and then to either drag the diagram to the new position or move the sides of the diagram to their new size holding the left mouse button pressed.

The program automatically selects a sensible axes scale for graph visualisation. If the "User-defined axes" button is clicked a dialog box opens allowing the "Use the following axes values" check box to be activated. The required minimum and maximum distances and velocities can then be given. The x-axis can be displayed on a logarithmic scale by activating the appropriate check box.

Beside the automatic display of the footing vibration velocity in the diagram, the vertical ground vibration velocity and the horizontal and vertical vibration velocity for floors and walls can also be shown. Activate the required check boxes.

The resulting vibration velocity value for the distance to the building entered in "Edit/System parameters" is displayed in the diagram if the "With individual values" check box is activated in the dialog box. The area behind the graph of the footing vibration velocity is backed using the colour defined by clicking the "Edit colour" button if the "Diagram coloured" check box is activated.

The distance at which the vibration velocity graphs begin is defined using the input in the "Min. distance [m]" box and to which distance on the x-axis using "Max. distance [m]". The total length of the x- and y-axes is automatically adapted if the specified distances are altered or are defined by the user using the "User-defined axes" button (see above).
