Good day everyone!
Harvie here, I'm literally new to opensees and is trying to understand how this works. I'm trying to read stuff from the wiki but I can't seem to find what I'm looking for.
I'm trying to model low to mid rise structures as MDOF concentrated mass shear models and high rise structures as MDOF concentrated mass flexural-shear model for an urban scale analysis for my thesis. I am going for DEM since data available are on macro scale such as building height , building footprint, etc and no specific dimensions for the beams and columns since data gathering is difficult for an urban-scale analysis.
I know that masses can be modelled as concentrated nodal masses but my problem is modeling the shear and flexural springs and how are these gonna be connected to the nodal masses.
Any help is greatly appreciated! Thank you!

Re: Help with MDOF shear and MDOF flexural-shear modeling
You can use zerolength element to model the shear and flexural springs. However the shear and flexural springs will not be coupled.

hello @selimgunay!
Thank you for replying, I'm actually thinking of using 2-node links, is this possible?
Or should I use zerolength elements and connect them with rigid links?
