REFERENCE FOR DESIGN FOR BOX GIRDERS

REFERENCE FOR DESIGN FOR BOX GIRDERS

(OP)
Hi
I am in need of some good reference book on design of steel box girders.I specifically need the moment of inertia requirements for diaphragms
at the point of eccentric loading where torsional moment and a vertical load is applied to only one web(like from cantilever platforms attached to one web only).Any help would be highly appreciated.
Thanking you in advance for your help.

RE: REFERENCE FOR DESIGN FOR BOX GIRDERS

The Lincoln foundation had a publication on the design of orthotropic plates; I don't know if it's still available...

RE: REFERENCE FOR DESIGN FOR BOX GIRDERS

Orthotropic is likely only going to give small three-sided boxes and trapezoidal shapes with no diaphragms to speak of.

The best shot here is one of the AISC Design of Steel Highway Bridges Handbook.  In it they have design examples of steel box girders.  While the analysis is done by computer, most of the design components are shown by hand for clarity.

As I recall there is a box available on the design of box girders...just don't recall the author or date, but I know it is from the 70s.

I meant to say there is a text available on the design of steel box girders.  Very theoretical as I recall.

RE: REFERENCE FOR DESIGN FOR BOX GIRDERS

Is this cantilever loading attached directly to the web?

Is this steel box girder composite with a concrete deck?

Thanks for that great link, bridgebuster!

your welcome

RE: REFERENCE FOR DESIGN FOR BOX GIRDERS

Ditto... Dik

RE: REFERENCE FOR DESIGN FOR BOX GIRDERS

CHARLESCOSTA,

With boxes torsional warping stresses should be looked at, the provided manual states that if less than 10% of long. bend. stress there is no need to consider it.

Thanks for all your replies.I am referring to steel box girder with plate diaphgrams like the ones used in
overhead cranes where drive platforms are directly attached to one web.Voyageofdiscovery which manual are you referring to?

RE: REFERENCE FOR DESIGN FOR BOX GIRDERS

Hi,

The "manual" I refer to is the "AASHTO-LRFD DESIGN EXAMPLE HORIZONTALLY CURVED STEEL BOX GIRDER BRIDGE".  This is obviously specific to bridge design.

RE: REFERENCE FOR DESIGN FOR BOX GIRDERS

I should have said "example", my mistake.

RE: REFERENCE FOR DESIGN FOR BOX GIRDERS

Another good link, bridgebuster.

RE: REFERENCE FOR DESIGN FOR BOX GIRDERS

thanks
