Earthquake

In the Visual-Q4M it is possible to perform analysis with:

• Input Motion X - Component
• Input Motion XY - Component

For to perform an analysis both in X and Y, the two components of the dynamic load must have the same number of records and the same time step. Is not possible perform an analysis only the Y-Component. The Visual-Q4M has the algorithms for signal analysis that can be processed for:

• Acceleration
• Velocity
• Displacement
• Pseudo- Acceleration
• Pseudo- Velocity
• Pseudo- Displacement
• Fourier Transform Spectrum
• Power Spectrum

All accelerograms can be scaled.

The internal database can be updated automatically with a series of standard Input Motions
