3d earthquake software
Non-planar faults (currently limited to variable dip, rectangular elements)
Slow and fast, aseismic and seismic slip transientsĭynamic weakening (thermal pressurization) Microphysically based frictional model ( Chen-Niemeijer-Spiers model) Rate-and-state friction, with velocity cut-offs, aging and slip laws To get started with QDYN, see the documentation. It is equipped with user-friendly MATLAB and Python interfaces and graphical output utilities. QDYN implements adaptive time stepping, shared-memory parallelization, and can deal with multi-scale earthquake cycle simulations with fine details in both time and space. The medium surrounding the fault is linear, isotropic and elastic, and may be uniform or (in 2D) contain a damaged layer. In 3D it handles free surface effects in a half-space, including normal stress coupling. Loading is controlled by remote displacement, steady creep or oscillatory load. QDYN includes various forms of rate-and-state friction and state evolution laws, and handles non-planar fault geometry in 3D and 2D media, as well as spring-block simulations.
#3d earthquake software software
QDYN is a boundary element software to simulate earthquake cycles (seismic and aseismic slip on tectonic faults) under the quasi-dynamic approximation (quasi-static elasticity combined with radiation damping) on faults governed by rate-and-state friction and embedded in elastic media.

The main deliverables of this project will be the software for the 3D numerical code for wave propagation andįor the automatic classification of the level of risk at each location of the study area, an experimental database use of pattern recognition methods developed in artificial intelligence to identify the most relevant siteĬonditions that control the level of risk, and to provide the basis of guidelines for practical applications. (Greece), one from Japan (Ohba Ohashi bridge) and the Nya Ullevi Arena in Gothenburg (Sweden) Simulations on simplified models using existing codes will be performed - use of strong and weak motion recordings from local seismometer arrays, including one from Kefallonia Island 5mx5mx2m) cyclic soil-foundation interaction tests with saturated sand at near-failureĬonditions to be carried out at the ELSA reaction wall facility of JRC (Joint Research Center) Ispra.
an original hybrid finite element- spectral appoximation algorithm that constitutes the basis for the 3D The field, and laboratory tests, salient among which are: The objectives will be attained by a combination of analytical tools and software, experimental observations in To formulate improved criteria for taking site effects into account, and to incorporate them into preliminary, simplified guidelines for practical applications. To identify new practical classifications of site-dependent ground motion hazard by th einnovative application of artificial intelligence techniques. To demonstrate the practical use and reliability of the numerical code through validation with data from local seismic arrays. To create an innovative three-dimensional (3D) numerical code for wave propagation in linear and nonlinear earth media, for analysing earthquake and man-made vibratory ground motions in the presence of significant site effects, including foundation interaction domains.
