How to get the max value from a plot defined in a function

Hello, PTC community,

I defined a function in Mathcad prime 9 for plotting the displacement response (Y-axis) versus time (X-axis). This plot is for a single time period T.

I want to get the maximum displacement (Y-value) from the graph for each time period T.

For example, I want the maximum displacement values from the plot for Time period T if T= 0.02, 0.2, 4.

eg

T= 0.2 max. displacement: xx

T:0.4 max. displacment xxx and so on.

I attached the mathcad file and it imports a text file containing earthquake data which is also attached for your reference.

I would really appreciate your help.

Thanks,

Abdur

Here are my 2 cents. A simple function should do the job.

Thank you very much for responding and helping.

I have been using Mathcad to apply the Newmark method and successfully plotted the displacement versus time for earthquake ground motion. However, I'm facing a challenge in extracting the maximum displacement values for each time period (T=0.02s to 4s in increments of 0.02s) from my plot.

My goal is to create a new plot with time on the X-axis and the corresponding maximum displacement values on the Y-axis (Response Spectrum Curve)

I've attached the Mathcad file for reference. I would greatly appreciate your insights.

Thanks,

Abdur
