Sometimes when we work with seismic projects at Fluxiss, we feel every building “tell its story” under an earthquake. And that’s exactly what Time History Analysis does. It allows us to apply real ground motion records to a structure and observe how every second unfolds. This is the method we trust when someone wants accuracy and not assumptions.
In our earthquake engineering, the one thing that stood out was how unpredictable ground motion can be. Codes like ASCE 7-22, Eurocode 8, and BS EN 1998 push for real seismic behaviour, not approximations and that’s where time-domain simulation becomes essential.
At Fluxiss, we run seismic time history simulations for clients in Los Angeles, New York, London, Dubai, Abu Dhabi, because the risk profile of every region is different.
Time History Analysis is when we feed real earthquake waveform input into a structural model and track how the building behaves every millisecond.
That’s it, simple, real, and data-driven.
We start with ground motion records sourced from research bodies like PEER NGA, USGS, or NEHRP.
These records become the raw input for:
We use this when the structure stays elastic. Codes like ASCE 7-22 allow it, especially for regular buildings.
This is the deeper dive, where we watch elements yield, crack, and degrade.
This type is ideal for performance-based design, tall buildings, critical facilities, and high-seismic zones like California, Alaska, Turkey, UAE, and Greece.
When clients approach Fluxiss for time history structural evaluation, here’s what we walk them through:
We build the structural model with its mass, stiffness, damping, nonlinearity, and real boundary conditions.
We apply multiple accelerograms, often scaled or matched to the target spectrum (ASCE / Eurocode).
This is where we observe:
We prepare reports for code officials, third-party peer reviewers, or internal design teams.
Cities we frequently support:
San Francisco, Seattle, Los Angeles, Houston, Dubai, Abu Dhabi, London, Manchester.
Clients usually ask when Time History is better than Response Spectrum. Here’s what we explain:
Both are valid. Time History is used when realism is critical.
As someone who’s seen how inaccurate assumptions cause failures, we take this service seriously. Fluxiss delivers:
Get your earthquake analysis done with accuracy and transparency.
High-rise buildings, critical infrastructure (hospitals, power plants), structures with complex irregularities, and projects using advanced systems like base isolation typically require detailed earthquake motion modelling. It’s mandated by codes like ASCE 7 for high-seismic zones.
Ground motion records are the acceleration-versus-time traces from past earthquakes. For accurate seismic time history simulation in NLTHA, codes require us to use a suite (often 7 to 11 pairs) of these records. We scale them to match the site's target design spectrum, reducing uncertainty and ensuring a robust dynamic earthquake modelling result.
Yes, absolutely! While we are a US-based engineering company, our expertise in global standards like ASCE 7, Eurocode 8, and other regional codes allows us to provide advanced seismic dynamic time study and structural time history study for projects across the USA, UK, Europe, and the Middle East, including cities like New York, London, and Dubai.
We’re proudly serving clients across the USA, UK, UAE, and Europe. From corporate giants to research labs and the shipping industry,
