Floor Vibration on Corridor Bridge
Floor Vibration on Corridor Bridge
(OP)
I am designing a simple-span interior bridge, spanning some 45ft, 8ft wide, second floor corridor loading (80psf LL).
I know of ASIC Design Guide No11 - Floor vibrations due to Human Activity; but I have never really looked too in depth through it. I was wondering if anybody had any experience with similar designs and if a the frequency of occupants is even an issue to really warrant a close examination, or would some quick numerical natural frequency clacs be sufficient in your opinions?
Thank you,

RE: Floor Vibration on Corridor Bridge
another solution you can go for span/1000 but according to AASHTO that does not guarantee to exclude the Sick Feeling that could occur to the pedestrians
Another easy accurate solution is: get your frequency from the FEA and compare it with the values given in" NCHRP 20-07 TASK 244
