Geotechnical dynamic analysis – QSIM

190.00 esc. IVA

QSIM software performs the analysis of slope stability in dynamic conditions using Newmark’s method.

The software offers as a result the trend displacements and velocities during the earthquake and the maximum displacement. It also generates design artificial accelerograms and more.

Video Tutorial


Newmark’s method models a landslide as a rigid block sliding on an inclined plane; movement occurs when horizontal acceleration exceeds the critical value kc that is calculated by a pseudo static analysis.When acceleration falls below this value motion proceeds with null acceleration.

Other features:

  • Import of accelerograms from any external file
  • Integration of design accelerograms in the automatic generation
  • Computation of response spectrum for design accelerogram
  • Computation of response spectra according to normative for ultimate limit state ULS, for damage limit state and for elastic limit state, horizontal and vertical
  • Superimposition of the response spectrum of the design accelerogram and normative spectrum to establish compatibility
  • Returns the diagrams of accelerations, velocities and displacements
  • All graphics can be exported and printed
