QUAKE/W 2012 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!
