Dynamic earthquake analysis

QUAKE/W is a powerful finite element software product for modeling earthquake liquefaction and dynamic loading. QUAKE/W determines the motion and excess pore-water pressures that arise due to earthquake shaking, blasts, or sudden impact loads.


Key Features

Dynamic Stress Analysis

QUAKE/W models dynamic stresses arising from earthquake shaking or dynamic point forces from a blast or sudden impact. QUAKE/W simulates the impact of these stresses on earth structures.

Earthquake Records

Earthquake time history records can be imported and scaled for a dynamic analysis. Modify the peak acceleration and duration to ensure the values used in the QUAKE/W analysis represent site-specific conditions.

Newmark Analyses

The QUAKE/W computed dynamic forces can be used in SLOPE/W to compute yield accelerations and potential permanent deformations for each trial slip surface.

Excess Pore Pressure

Excess pore-pressures computed by QUAKE/W together with the initial static pore-pressures can be used in SLOPE/W to examine the effect of the elevated pore-pressures on stability.


Solutions

QUAKE/W can model the dynamic behavior of almost any earth structure

Newmark Deformations

This example demonstrates how the results of a QUAKE/W analysis can be used in conjunction with SLOPE/W to estimate the permanent deformations that may occur as a result of the inertial forces associated with an earthquake. This type of permanent deformation analysis is referred to as a Newmark analysis.

Soil-Structure Interaction

The response of the ground can be influenced by the rigidity of a structure. Stated conversely, the presence of a stiff structure could possibly affect the response of the ground to earthquake shaking. This example illustrates some modeling techniques used to include the effects of a structure, including the mass of the structure, in a QUAKE/W analysis.

Upper San Fernando Dam

The San Fernando earthquake occurred in California in 1971. The earthquake created a liquefaction failure at the Lower San Fernando Dam and Reservoir. This analysis demonstrates the advantages of using QUAKE/W with other GeoStudio products to analyze the multiple issues that arose with this case.

Blast Vibrations

This example considers the dynamic response of a pit slope to a blast charge. The project file contains an equivalent linear QUAKE/W analysis as well as a SLOPE/W stability analysis.
