Modal Vertical Earthquake Analysis with the ProtaStructure 2025

Modal Vertical Earthquake Analysis with the ProtaStructure 2025

With its new features for advanced earthquake engineering applications, ProtaStructure now enables you to perform modal vertical earthquake analyses. ProtaStructure reflects the effects of vertical earthquake action to design by following two methods:
  1. Approximate Static Approach
  2. Modal Spectrum Analysis Method
In the Approximate Static Approach, vertical vibration modes and a dedicated vertical spectrum are not considered. Instead of those, the result from gravity load case is multiplied by a fraction of horizontal spectral acceleration. On the other hand, in Modal Spectrum Analysis Method, the vertical vibration modes of the structure are considered together with a vertical acceleration spectrum.

In this video, Prota Software Product Manager Mustafa Tan demonstrates how to perform the modal vertical earthquake analysis with ProtaStructure through a live demonstration. Moreover, he shows how to visualize the analysis results on the analytical model.




Notes
As a structural engineering software designed by structural engineers, ProtaStructure provides its users with comprehensive tools to ensure safe design. With the ProtaStructure 2025, significant new seismic capabilities have been introduced and the code-coverage of the software has become even more expansive. You can check out "ProtaStructure Suite 2025 New Features" document to explore all the essential new capabilities, and you can find the table of supported design codes on our website.
