I am wondering what are the differences between nonlinearBeamColumn, forceBeamColumn and dispBeamColumn elements and their usages?
Thanks
What are the exact difference between following elements?

Re: What are the exact difference between following elements
the nonlinearBeamColumn and forceBeam column are the same. the nonlinearBeamColumn command is not in the manual anymore.
the dispBEamColumn is a displacement based element (given nodal displacements, it can determine section deformations at gauss points along element assuming linear curvature between end nodes).
the forceBeamColumn is a force based element (it iteratively finds section deformations at gauss points for case where beam is in force equilibrium given end displacements .. force method)
see the documentation listed in the commands for the force based element for a more detailed description. there was also a webinar on the topic. it is theoretically the more correct element.
