Multi-Mode Pushover Analysis in ProtaStructure 2025

Описание: With its advanced analysis module, ProtaStructure supports you in advanced earthquake engineering applications as well. For this purpose, a number of new capabilities have been introduced to this module in the 2025 version. One of the most significant one of these is multi-mode pushover analysis.
Traditional pushover analysis utilizes the primary vibrational mode of the structure, and it is viable for a limited range of buildings. Hence, for buildings suffering from higher mode effects or irregularities, single-mode approaches are not sufficient.

In the ProtaStructure 2025, on the other hand, the Chopra Goel’s (2002) Modal Pushover methodology has been adopted. You can find the further details of this method in this video and on the ProtaStructure 2025 New Features document published on Prota Help Center. Additionally, you can visualize the results of both multi-mode pushover analysis and time-history analysis easily.
