Finite element analysis for Earthquake engineering: Structural, Soil and Rocks dynamics

FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization

For many non-standard structures, a proper earthquake design requires a dynamic finite element analysis. For simple assessment, a linear analysis in frequency domain may be sufficient. However, for other applications, the full nonlinear characteristics of possible failure mechanisms and interaction of the structure with ground and environment need to be considered in a nonlinear time stepping analysis. Enteknograte offers solutions for both simple linear dynamic analysis, which can be applied for the design of structures, and also full nonlinear dynamic analysis taking into account the loading history of the structure.

Types of Earthquake Analysis

  • Linear transient analysis with different time integration schemes
  • Direct frequency response analysis
  • Modal response analysis & Spectral response analysis
  • Nonlinear transient analysis with different time integration schemes
  • Hybrid frequency-time domain analysis
  • Pushover load & Pushover analysis

New structures in earthquake sensitive areas are designed to sustain earthquakes without danger of damage or collapse. But if the condition of the structure has been unidentifiably changed, eg. by damage to the structure, deterioration of materials or altered loading, then the effect on earth- quake resistance may be significantly altered.
