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:
- Approximate Static Approach
- 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.

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
