Re: Pedestrian bridge vibration and strengthening

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The March edition of Modern Steel Construction has an
article about vibration problems.  You might give it a look.
Also, try AISC Design Guide 11.  I believe that is the
most recent publication available.
