Graphing is critical for the interpretation In a QUAKE/W analysis can be used to compute the degree of permanentĭeformation with a stress-redistribution analysis in SIGMA/W. Information on potential liquefaction zones generated Integrate with SIGMA/W to Model Permanent DeformationĬauses large strength reductions, which may lead to permanent deformationsįollowing an earthquake. The time required for dissipation of excess pore-water pressures generated during an earthquake can be determined by inputting QUAKE/W results into a SEEP/W analysis. Integrate with SEEP/W to Dissipate Excess Pore-Water Integrate with SLOPE/W to Model Liquefaction ZonesĪreas indicated as potential liquefaction zones in QUAKE/W can be evaluated in a SLOPE/W analysis to assess the influence of liquefaction on stability, given the associated liquefied strength reduction factor. Integrate with SLOPE/W to Model Excess Pore-Pressures andĮxcess pore-pressures computed by QUAKE/W can be considered in a SLOPE/W analysis to examine the effect of the elevated pore-water pressures on stability. Greatest potential permanent deformation.

The stability results can be sorted to identify the trial slip surface with the The QUAKE/W computed dynamic forces can be used in SLOPE/W to compute yieldĪccelerations and potential permanent deformations for each trial slip surface. Potential permanent deformation in earth slopes arising from dynamic earthquakeįorces. Integrate with SLOPE/W for Newmark Analyses Structural stiffness on the dynamic response of the earth structure. QUAKE/W analysis to investigate the effect of both axial and flexural Used in the QUAKE/W analysis to represent site-specific conditions. Peak acceleration and duration can be modified in order to adjust the values Vertical earthquake accelerations are imported, the QUAKE/W allows you to import and scale earthquake Which the horizontal stresses exceed the vertical. This provides the ability to model heavily over-consolidated soils in Used to create a displacement boundary function.Įither Poisson’s ratio or by specifying an initial K For example, acceleration or velocity data over time can be As such, actual field data over time or user-specifiedįunctional relationships can be pasted into QUAKE/W. With the entire GeoStudio suite, QUAKE/W makes broad use of generalizedįunctions for boundary condition definition. Hydrostatic pressure, displacement, force, or spring boundaries. G-reduction functions, and typical soil classifications for Cyclic numberĬomprehensive Range of Generalized Boundary Conditionsīoundary condition options including normal/tangential stress, X-Y stress, Process requires only fundamental material information, such as the N exponentįor pore-water pressure functions, confining stress and plasticity index for QUAKE/W will use these properties to identify zones ofĮstimate Material Properties for Typical MaterialsĮstimated using built-in properties for typical materials. Liquefaction potential by defining a collapse surface and steady-state strengthįor the material. Structure can fail at strengths below its conventional strength as defined byĮffective c' and φ' parameters. Vary with cyclic strain for successive iterations. QUAKE/W performs an Equivalent Linear analysis, the Damping Ratio and G modulus Number, pore-water pressure, damping ratio, and G modulus reduction. This includes functions for the overburden correction function (Ks), shear stress correction (Ka), cyclic The Cyclic Stress Ratio (CSR) approach is used forĬalculating excess pore-pressures arising from dynamically induced shearĪllow you to use any laboratory or published data. Three constitutive models are supported: Linear-Elastic, Equivalent Linear, and an effective stress Any natural, near-horizontal ground sites with potential for excess pore water pressure generationĬonstitutive Models and Material Properties.QUAKE/W can model the dynamic behavior ofĪlmost any earth structure you will encounter in your geotechnical, civil, and Alternative time intervals can be used for other dynamic analysis types. Means integrating a set of time intervals from the start to the end of theĭefined earthquake record. When analyzing earth structures subjected to earthquake shaking, this The potential permanent deformation associated with earthquake shakingįormulation based on direct integration in the timeĭomain.The liquefaction potential of earth structures subjected to earthquake shaking.The stability of slopes that are subjected to inertial forces arising from earthquake shaking.Therefore, it is designed primarily for assessing: The motion and excess pore-water pressures that arise due to shaking. QUAKE/W can be used to analyze earth structures subjected to earthquake shaking or dynamic point forces from a blast or a sudden impact load. Your model, analyzing it, and viewing results.
