RBOC for the Fall

  • I am teaching graduate level Structural Mechanics at Eastchester for the first time this fall. I will use the Fundamentals of Structural Mechanics book by Keith Hjelmstad. Expect some posts on how to use OpenSees to solve structural mechanics problems for beams, plates, shells, etc.
  • I will do NaBloPoMo again this November. Writing a post every day for a month is not a new thing, but it remains novel in the earthquake engineering corner of the blogosphere. I have posts for about half the month planned out, so if you have any ideas to help me round out the rest of November, please let me know.
  • The blog turns 2 in two days. I’ll summarize stats again.

  1. Thank you Dr Scott. I request you to write on how to use the ArcLength integrator. Additionally, you can consider a topic on why we need to be careful about groundMotion while doing multisupport excitation analysis.

    1. The arc-length integrator would be a good topic, like what arc-length should be input. Thanks! For the groundMotion, do you mean the trapezoidal vs. Simpson integration of ground acceleration to get ground velocity and displacement?

      1. Thanks Dr Scott. For groundMotion, it’s about which is safer, the record input in the format of acceleration or displacement history? Because I think if we input acceleration history, there is going to be an internal conversation by trapezoidal or Simpsons rule. Both of these rules can give us non-zero displacement at the end of the ground motion duration or sometimes totally weird displacement history, if the accelerogram was not processed well ( base-line correction and noise etc). Hence, it is better to give directly the displacement history as ground motion input in multisupport excitation analysis. What’s your take on this point?
