CONTROL OF SLAB VIBRATION

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Title: Seismic Base Shear - Tank With Supported Bottom

GREETING ALL.

 

THERE IS  ONE SLAB THAT PRESENTS PROBLEMS OF VIBRATION FOR THAT WHICH  

I AM DESIGNING A STRENGTHENING.

THE SLAB IS  RETICULAR  OF  8.5 M  OF SPAN WITH  BEAMS OF 0.4*0.6. And THICKNESS IS  0.25 M 

MI  IDEA IS  to PLACE TWO METALLIC TUBULAR BEAMS BELOW  SLAB OF 250X300 MM.

MY PRINCIPAL IDEA it is to CHANGE FIRST VERTICAL VIBRATION MODE AND to TAKE AND TO MOVE AWAY FROM THE PERIOD THAT IT PRODUCE WITH THE  WALKING OF PEOPLE ( 2  TO 4 CPS)

THE  CONSULTATION IS THAT IF SOMEBODY KNOWS OR  IN THE PAST   WORKED  WHIT THIS TYPE OF STRENGHTENING.  TO AVOID THIS   PROBLEM OF VIBRATIONS IN RETICULAR SLAB. 

ANY IDEA IS VERY IMPORTANT.
