Seismosoft develops specialist earthquake-engineering software (and training) to help engineers and researchers assess, strengthen and retrofit structures subjected to seismic actions.

Founded in 2002, we have always focused on two things: scientific rigour and ease of use—so advanced methods can be adopted efficiently in both practice and academia. Our applications are requested at around 1,000 downloads per month and are used in 110+ countries by universities, consultancies and public organisations.

We enable modern seismic workflows, from ground-motion processing to nonlinear structural analysis and retrofit design—supporting performance-oriented studies, comparison of strengthening alternatives and clear reporting for decision-making. While our core focus is building strengthening, our tools are also used across broader structural dynamics and infrastructure applications where reliable nonlinear modelling and seismic input handling are essential.

Our product suite covers the full ground-motion-to-structural-performance workflow:
• SeismoBuild – assessment & strengthening of RC buildings
• SeismoStruct – structural assessment & retrofitting (nonlinear analysis)
• FRP Designer – FRP strengthening design of RC columns & beams
• SeismoSelect – selection & scaling of ground-motion records
• SeismoSignal / SeismoSignal 3D / SeismoSpect – strong-motion processing & spectral analysis
• SeismoMatch – response-spectrum matching
• SeismoArtif – generation of artificial earthquake accelerograms

Beyond software, we share know-how through webinars and structured online courses on seismic analysis, strengthening and retrofitting, with hands-on projects using our tools.

Users are supported with free trials, academic licences, documentation and a support ecosystem—so teams can move from learning to delivery quickly.

By making powerful, user-friendly tools and training widely available, we aim to support the global effort to reduce earthquake risk and improve resilience.
