Re: Drift at top and rotation/curvature in plastic hinge zone

[Subject Prev][Subject Next][Thread Prev][Thread Next]
In other words, rotation (radians) = Drift (percentage) ?

e.g. .005 [0.5%] x height = .005 radians x height ?

This would assume that the plastic hinge is at the very bottom of the
column, and not over a length, Lp.

Any other comments??
