Re: Strange seismic response on high frame building

Dear all... I’m having similar problems with concrete 06. In cyclic behavior, particularly after an unloading branch, the monitored fiber defined in the model presents positive strains and negative stress. I defined my parameters in SI units. Do you think that this could be the problem and i need to...

Dear vesna.

I used the gettime comand and a variable to limit the time inside the while cycle...problem solved.
thanks for your help...

Re: impose displacement

Dear Vesna: I made a material library script that I source for other scripts and always have the expected form in the curve. In the steel 02 model, the unloading zone is a straight line instead of the curve that Menegotto Pinto (or Prof. Filippou implementation) R parameter defines. I have very smal...

impose displacement

Dear all: I want to impose a curvature history to a zero length element in order to analyse the corresponding moment-curvature response. The curvature history doesn’t present regular increments. I made a for each cycle for the n incremental curvatures of the history and i used the cyclic static anal...
