Member redundancy analysis

This example shows a simple method for carrying out a member redundancy assessment using pushover analysis in Usfos. The main aim is to understand how the structure behaves when certain members are removed and to evaluate its overall strength and stability.

In this example, selected members are removed based on criteria such as their importance, existing damage, or fatigue life. The removal is done step by step to avoid instability and to better observe how the structure responds to each change.

The pushover analysis is then performed by gradually increasing the load until the structure shows significant deformation or failure. Key results such as displacement and load capacity are used to assess the structure’s redundancy.

Overall, this example helps illustrate how member removal affects structural performance and highlights the importance of careful analysis to ensure reliable results.
