QUAKE/W

Overview

QUAKE/W is a geotechnical finite element CAD software product for the dynamic analysis of earth structures subjected to earthquake shaking, or point dynamic forces from a blast or a sudden impact load. QUAKE/W determines the motion and excess pore-water pressures that arise due to shaking. Its comprehensive formulation makes QUAKE/W well suited to analyzing a wide range of problems.

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

Beginning an analysis is as simple as defining the geometry by drawing regions and lines that identify soil layers, or by importing a DXF™ file. Then specify material properties, import earthquake records, and apply boundary conditions and structural elements.

Viewing the Analysis Results

Once you have solved your analysis, QUAKE/W offers many tools for viewing results. Animate the motion by viewing 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 prepare the results for your report by adding labels, axes, and pictures, or export the results into other applications such as Microsoft® Excel® for further analysis.

Typical Applications

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
• plus many more!
