Seeking a reference for design of steel baseplate with stiffeners (BS)
Seeking a reference for design of steel baseplate with stiffeners (BS)
(OP)
Hi,
I have been searching for a while for a good reference guide to design steel baseplate with stiffeners, unfortunately the BS5950 doesn't cover baseplate with stiffeners.
The reference is preferred to be related to British standards.
Thanks in advance
Regards

It can be purchased directly from the publisher at a very reasonable cost https

To design base plates you will need to undertake a plastic analysis and don't forget prying when checking the bolt capacity.
RE: Seeking a reference for design of steel baseplate with stiffeners (BS)
I was especially asking about (Tension case) because what I have heard is that for columns on tension (some truss chords) you 'have' to provide stiffeners to the base plate.

As long as your yield line/plastic analysis is compatible with your building code stiffeners aren't absolutely necessary, but they could be more economical.
How big a tension load are you looking at?

Sorry I didn't notice your comment
Thanks for the clarification
It - (Tension)- could reach up to 3600 kN but mostly around 1500-2000 kN.
I have been through some recommendations of providing stiffeners if you have considerable tension also if you have big bending moment.

I will see if there is a possibility to do that.
I have one small last question, if you have combined bending moment acting on the column, how would you deal with it on baseplate?
would you consider each axis with its own bending?
or
combine them and find the angle of the axis of the resultant bending relative to x-axis?
or
would you deal with it as a footing with combined bending?
I didn't read or see much talking about such case in the textbooks I have been through.

Anyhow, if that can't be done first design the bolt group. Then work out each bolt reaction from the combined biaxial moment/tension. Using those forces you can work backward to determine the plate capacity with a yield line analysis.
A job like this may warrant an FEA, you don't want to stuff it up by assuming the wrong yield line pattern.

The last question was not related to the first one.
I appreciate your helpful information.
Best regards
