Generalized material property functions allow you to use any laboratory or published data. Three constitutive models are supported: a Linear-Elastic model, an Equivalent Linear model, and an effective stress Non-Linear model. QUAKE/W uses the Direct Integration Method to compute the motion and excess pore-water pressures arising from inertial forces at user-defined time steps.
QUAKE/W can be used to analyze almost any dynamic earthquake problem you will encounter in your geotechnical, civil, and mining engineering projects.
Easy to Use
Defining a Dynamic Earthquake Model
The unique CAD-like technology in QUAKE/W allows you to generate your finite element mesh by drawing regions on the screen. You can then specify material properties, import earthquake records, and apply boundary conditions and structural elements. If you make a mistake, you can correct it with the Undo command.
Viewing the Analysis Results
Once you have solved your problem, QUAKE/W offers many tools for viewing results. Animate the motion by viewing at the displacements for successive steps. Look at the complete displacement, velocity and acceleration history record at key points. Perform a spectral analysis at these points to study the ground motion frequency and seismic characteristics. Generate contours or x-y plots of stress, strain, pore-water pressure, and over 35 other parameters. Show the shaded liquefaction zone. View any stress state as a Mohr Circle with the associated space-force diagrams. Then export the results into other applications, such as Microsoft Excel or Word, for further analysis or to prepare presentations.
QUAKE/W can model the dynamic behavior of almost any earth structure, including:
- • Earth embankment dams
- • Natural soil and rock slopes
- • Loose ground deposits
- • Estimation of post-earthquake deformation
- • Impact loads from dynamic blasting
- • Any natural, near-horizontal ground sites with potential for excess pore-water pressure generation during earthquake shaking
