I am designing a cable stay bridge for my master’s thesis. I want to conduct a non-linear analysis and plot the load-deflection curve of a particular node at the end in Microsoft Excel. I have tried running the analysis using ASE TH3, but the deflections I am getting for the loads I have applied are linear. I also tried using module Star2 but still got a linear result for the deflections. Please can anyone help me with an easy approach as this is holding me back in making progress on my thesis?
