mezzanine

[wayne87]

HI

I would like to construct a mezzanine floor, on top of some offices for storage.

there are already trusser which are 50mm x 150mm with a span of 3m. The trussers are 850mm apart i would like to use 21 mm shutterply wood flooring where each board is 1.2m x 2.4m.

How can calculate the max load per a m2 that the floor will be able to take and will it be a problem that the trussers are 850mm apart.

please let me know asap

thanks

if you doubled up the joists i.e. every 450mm centres then you will be ok for domestic loading at that joist depth.

not sure about the shutterply flooring though.

Thanks
but unfortunately that still does not help me, i need to know how to calculate the max load per a square meter using bending moments, allowable stresses ect.

so that i can determine a value per a square meter.

please advise

thanks wayne

Do you have a background in Engineering?

What you ask took most of us a few years of college and a few years of practice to learn.

Shuttering ply is pretty much ****e quality from a structural point of view, and with a span of 850mm it's going to flex alarmingly.

You can probably get hold of a copy of BS 5628 from somewhere which is the timber design code, or try TRADA for design manuals, but the deflection will pretty much rule out what you are trying.

Hi there

I am actually studying meachanical engineering, i have done some calculations and i was just trying to check if i was on the right path, i went to see my lecturer this morning and he helped me iron out the some of the mistakes i was making .

But yes you are certainly right 850mm is way to far apart.
Im just going to lay more trussers between and it should be ok for the application of light storage.

Thanks so much for the guidance i really appreciate it.

cheers
