QUAKE/W
有限元素地震動態分析
for finite element dynamic earthquake analysis

Features
  • 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!
Overview

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.
