- Linear analysis using linear-elastic soil properties.
- Equivalent Linear analysis, which varies soil properties for successive iterations (Damping Ratio and G-Modulus vary with cyclic strain for successive iterations).
- Generalized data point functions for specifying material properties, including functions for overburden correction function (Ks), shear stress correction (Ka), cyclic number, pore pressure, damping ratio, and G modulus reduction.
- Imported earthquake records; both horizontal and vertical acceleration vs. time records can be used.
- Scale peak acceleration and time duration of imported earthquake records for site-specific conditions.
- Boundary condition types include X and Y displacements, forces, pressures, and spring constants, as well as stress, fluid pressure, and self-weight gravity loading.
- Definition of liquefaction potential using a collapse surface and steady-state strength.
- Structural elements for soil-structure interaction; specifying both axial and flexural stiffness can affect the dynamic response of the system.
- History nodes show complete record of displacement, velocity and acceleration.
- Many ways to view results, including x-y plots, contours, deformed mesh, animation, spectral analysis, data tables, and Mohr circles.
- View most result parameters for static conditions, dynamic conditions, or both.
- View displacements, velocities and accelerations as relative values (the finite element results) or as absolute values (the results added to the earthquake record).
- And many more!
Integration with Other Applications
Use QUAKE/W results in a SLOPE/W stability analysis
Earthquake shaking of ground structures creates inertial forces that may affect the stability of the structures. The shaking may also generate excess pore-water pressures. Both the dynamic stress conditions and the generated pore-water pressures can be taken into SLOPE/W to study how an earthquake affects the earth structure stability and deformation. SLOPE/W can perform a Newmark-type of deformation analysis to determine the yield acceleration and estimate the permanent deformation of the earth structure.
Dissipate excess QUAKE/W pore-water pressures in SEEP/W
Excess pore-water pressures generated during an earthquake can be brought into SEEP/W to study how long it will take to dissipate them.
