Balustrade Design
Can anyone help me in the design of Mildsteel & Stainless steel Balustrade & Handrails systems for Stairs etc when it comes to loadings. I am a Draughtsman by trade and would like further knowledge when it comes to producing structural calculations for balustrade systems. When we need calculations producing we sub this work out to structural engineers who produce these calcs for us. I would like to be able to produce these calculations myself. Can anyone help me please.

RE: Balustrade Design
It is unlikely that someone is going to explain the intricacies of the Building regs and British Standards to enable you do that.

RE: Balustrade Design
You can get some information from approved document K of the Building Regulations and from BS6399. Well done for trying to broaden your knowledge but it is really a job for a structural engineer unless you are very experienced. Keep up your quest for knowledge I hope I've given you a starter.

RE: Balustrade Design
Thankyou for your help so far...i am fully aware of all the currant building regulations and standards which to follow. All i am in need of is someone to explain the basic theory behind the bending moment calculation used when working out the strength of the material for when you are working out balustrade spacings. I have to go out to chartered structural engineers to have calculations produced but i think it is always good to be able to undersatnd these things yourself. I really hope someone can help me in my quest. thankyou

RE: Balustrade Design
hopefully the Engineer you are going to is a fully paid up owner of a Professional indemnity insurance policy to cover his work, if anything was to go wrong people would be covered. if you did the design, you could be taken to the cleaners if it went wrong. As mentioned above this is not the place to start to learn bending theory,perhaps you could go to university, i went for 4 years to get the basics of structural engineering. what type of drawings do you do? steel, rc concrete, big buildings, houses?

RE: Balustrade Design
I produce drawings for architectural steelwork. I am wanting to calculate the bending moments on a balustrade system to determine if the balustrade will take the required "Horizontal Uniformaly distributed load" of 0.74, 1.5 & 3kN I know all the following points: 1. the steel material/section which i am wanting to use. 2. I know the property of the material i am using. 3. I also know the height to the top of the handrail which is 1100mm. I am wanting to determine if the material i am wanting to use will withstand the required load and the maximum spacings which i can have for my balustrade posts. I dont know the formula you would use to determine this. can anyone please help by e-mailing me some information or pointing me in the right direction. I am aware of all the building regulations and british standards which are followed when designing balustrade systems. It is just the case of proving the structural integrity of the material.

RE: Balustrade Design
My advice is very simple:go and get structural engineer with Professional indemnity insurance policy to cover his work,because if something gone wrong ,you be covered

RE: Balustrade Design
people keep telling me to go to a sructural engineer because of Professional indemnity insurance reasons....its not the case that i am wanting to make money out of knowing this its just that i would like to know how to do this out of interest. No money will be made by me knowing this. You could say that i am a very boring git but this is my hobby not just a job.

RE: Balustrade Design
if load is 0.74kn/m run, you need to know the height of balustrading and the spacing of the posts, in order to calculate the overall force and the bending moments.

RE: Balustrade Design
reading the above, you shoulfd have a full set of calculations to cover the design anyway, what did you recieve from your engineer, any calculations? these should detail all you need. i get the feeling we are all directing you in the coreect direction, a little knowledge is dangerous! we have people asking similar questions every working day, only giving part of the information and looking for the answer, we have to protect them from dangerous design. we are all responsible engineers and have a charter to adhere to. if you realy want to get an insight into the subject, there are lots of good books covering the basic of design available from technical book shops.
