Hi Christo,
Im a Mechanical Engineer current in a aluminium/fabrication industry, overseeing the designs & manufacturing of marquees.....
I have been involved in a new design for a double decker marquee, currently the designs for the marquee have been signed off by structural engineers. however the steel structure staircase for the double decker is abit of stumble block for me.
i was wondering of there are any guidelines or mandatory specifications for these types of steel structures. ie, total deflection for the supporting members, height to width ratio.
I have consulted with the go to material, SANS & SABS are very thin with this regards.
I will post the image of the modular design as reference,
Kind regards.
