QUAKE/W is a geotechnical finite element 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. Using QUAKE/W, you can determine 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.
Earthquake Record
Time History Records and easily be input into QUAKE/W for the dynamic analysis of your project. The user can specify a peak acceleration value to scale down the earthquake record imported.
Graphing and Output
For an excavation with a tie back wall using anchors, moment oscillations in the sheet-pile wall during the earthquake can be displayed at every time step for the acceleration record imported (and scaled). The figure shows the axial force in the free (unbonded) length of the upper anchor. Note that at time zero, the axial force is equal to the static force that would be obtained from a SIGMA/W analysis. The second figure below shows the variation of the axial force in the grouted length of the anchor during the shaking. The forces are, of course, the highest where the bonded length is connected to the free length portion of the anchor.
