Envelope Drift Recorder

Post by mkumar07 »

Hi Everybody,

I am looking for a recoder that provides me maximum (+ve, -ve, or abs) drifts for the nonlinear time history. Just like envelope node recorder that gives maximum displacements.

I need such option to scale the ground motions to produce a certain level of drift at any storey of the structure.

It would save me a lot of time.

Why don't you simply use the difference between the displacements of two nodes?

But you need to record the full history of nodes displacements and then determine the envelopes.

Although having a recorder that you need would be great. :P
