Hysteresis for flat slab-column connection

Post  DagoCR1 on Thu Apr 07, 2011 5:00 am

I have been trying to model flat slab-column connection to replicate results from Hwang and Moehle experiments. I have been using a modified takeda hysteresis model on a giberson beam for the behavior (making it thin alpha=0.5, beta=0) but I cannot get closer to the results I want. I tried concentrating the behavior on springs near the joint but I got results that were even farther off from the expected. I have read that there is a mckenna and fenves model available in opensees but not in Ruaumoko. Is there a better hysteretic model in Ruaumoko that I can use?

I have also thought that maybe including some capacity degradation parameter may help but I have had no experience with these parameters.
Any comments and observations will be very appreciated.

Hi Dago,

Quite difficult to answer without knowing all the details of the test and the modeling, but at least a figure in which you show the exerimental vs numerical results might give us a better idea..
