Hello,I have construct a 3x3 steel frame and then I have conduct a dynamic analysis.I can get some good results.However,When I use the display tool,I find my model may turn into the red sometimes.I just don't know why.The period I get can matched well! I don't konw what it meas.Could someone explain...

could anyone help me?Does anyone know what problems are?Please give me some help, I will be very grateful!!

The DFdata is the displacement history which I get from aforementioned website i.e. the displacement in the data displacement-force.

If anyone want run my code ,I can make a pack and email to you.I'm really a new guy,many theory I just don't konw.For me,I really want to solve this problem,however,I really don't have any direction now.Can anyone recommend some books or papers Which are helpfu to read?

Thanks ismailqeshta for your reply，and I will try you advice!

Hello,everyone,I'm a really new guy.I'm trying to use the opensees these days,but it was a relly great challenge for me.I have encountering many problems since I use the Opensees.Sometimes,it was the convergence.Sometimes,it was the model itself .Even I contructed a model and it can work very well,b...

Hello everyone, I have build a N-Story,N-Bay MRF based on the example in openseeswiki ,Pushover and Dynamic Analyses of 2-Story Moment Frame with Panel Zones and RBS ,but,it didn't work very well.Although I have examine the model many times,I can't find where my mistakes are.It really makes me very ...
