Super FLUSH/3D is a program for three-dimensional dynamic interaction analysis using the substructure method.
When analyzing dynamic soil-structure interaction, it is necessary to take into account the semi-infiniteness and nonlinearity of the ground.
SuperFLUSH/2D, which features special functions for boundary analysis and equivalent linear analysis of the ground, is widely used for its analysis code that handles dynamic soil-structure interaction.
- Combining the advantages of both the contact body and contact surface solutions, the substructure method (mixed solution) reduces the degrees of freedom to be handled and the required computing time.
- The "thin layer element method" is used to account for the infiniteness of the ground.
- Performs complex response analysis in the frequency domain using complex stiffness.
- Has analysis functions that can greatly reduce the time required to compute the impedance for a circular or rectangular foundation.
Overview of features
- Structures: 3-dimensional FEM models. Solid, beam, spring elements and more.
- Outputs the transfer function, response acceleration, stress, strain, etc.
- Various restart calculation functions
- 1/2and1/4model analyses
- Ground: stratified ground (thin-layer element method)
- Free soil analysis---equivalent linear analysis according to the calculated pullback of input ground motion and the strain-dependence of the soil
- Analysis of dynamic soil-pile-building interactions
