Create Artificial and Synthetic Ground Motions Matched to Target Spectra.

SeismoArtif is a powerful application capable of generating artificial earthquake accelerograms that perfectly match a specific target response spectrum. It utilizes advanced calculation methods to create artificial and synthetic ground motions from scratch.

While using real records is often preferred, SeismoArtif is the essential solution in regions with sparse seismic data, and for theoretical. parametric studies and code-based design, when access to real accelerograms is challenging or inappropriate.

Controlled Synthetic Generation

Generate ground motions with precise characteristics using industry-standard simulation models:

  • Accelerogram Generation: Use different computational approaches — including synthetic generation, random-phase methods, frequency-domain adjustments and even real-accelerogram adjustment — to best suit your project needs.

  • Envelope Shapes: Control the non-stationary characteristics of the shaking (duration, build-up, and decay) using standard shapes like Saragoni & Hart, Compound, Exponential, or Uniform.

  • Real Record Envelopes: Import envelope shapes from real earthquake records to introduce realistic characteristics to your synthetic motions.

  • User-Defined Spectra: Define user-defined spectral shapes, or simply compute the spectrum of a specific accelerogram to match against.

Validation & Verification

Ensure your artificial and synthetic records are engineering-ready. SeismoArtif provides real-time validation tools:

  • Response Spectra Calculation

Automatically calculate the Acceleration, Velocity and Displacement Response Spectra of the generated motion to verify it meets your design criteria.

  • Spectral Comparison

Instantly view the match between your synthetic record’s response spectrum and the target spectrum, including the Mean Spectrum Error (%) and Coefficient of Variation.

Who Uses SeismoArtif?

SeismoArtif serves a broad range of professionals and organizations working in earthquake- and structural-engineering — essentially anyone who needs credible ground-motion data, when real records are lacking or insufficient.

Typical users include:

  • Structural & geotechnical engineers performing seismic design and structural analysis of buildings and infrastructure — especially in regions where recorded ground-motion data are sparse, outdated or incompatible with code requirements.

  • Design offices & consulting firms engaged in performance-based seismic design, nonlinear dynamic analysis, or probabilistic seismic hazard studies — using SeismoArtif to generate suites of accelerograms matched to target spectra for different seismic scenarios.

  • Researchers and academic institutions studying structural response under earthquake loading, developing & validating new seismic-analysis methodologies, or comparing structural performance across different ground-motion inputs.

  • Designers and planners involved in retrofit or assessment of existing structures, where realistic dynamic input is needed but historically recorded strong-motion data may not exist for the site or code-level hazard.

SeismoArtif is used by engineers, consultants, academics or any practitioner that requires realistic, spectrum-compatible ground-motion records, when real earthquake data are missing or inadequate — enabling credible seismic analysis, design and researc

New in v2026

  • AI Assistant Integration: The new Seismosoft AI Assistant is now integrated to help you select the most appropriate envelope shapes and troubleshoot generation parameters for your specific seismic hazard scenario.

Key Capabilities

  • Efficiency without compromise. The intuitive interface, built-in exportability, and visual tools mean you can integrate seismic simulation into your workflow without cumbersome setup or steep learning curves.

  • Visual Interface: Fully visual environment for defining spectra, selecting envelopes, and viewing generated time-histories.

  • Batch Generation: Generate suites of accelerograms simultaneously to create a statistically significant dataset.

  • Seamless Export: Copy generated acceleration, velocity, and displacement time-histories directly to Excel, Word, or text files for immediate use in analysis software like SeismoStruct or SeismoBuild.

  • Support for global standards: Offers target-spectrum creation using the rules from more than 25 national building codes and seismic design standards worldwide.

Ideal For

  • Preliminary design studies when no suitable real accelerograms exist
  • Nonlinear dynamic analysis of new or existing structures
  • Generation of multiple ground-motion scenarios for performance-based design
  • Research, academic work or comparative studies of structural response under different seismic inputs
  • Projects spanning different countries and seismic code requirements

Completely visual interface. No input or configuration files, programming scripts or any other time-consuming and complex text editing requirements.

Due to its full integration with the Windows environment, SeismoArtif allows for numerical and graphical results to be copied to any Windows application (e.g. MS Excel, MS Word, etc.), noting that the plots characteristics can be fully customised from within the program itself.
