Dear experts,

I am doing stress analysis for building raiser piping around 160 meters long strait pipe, how to specify the clamp support on vertical raiser pipe for each 4 meter level, kindly advice if any standard practice .

Run a single, long riser with a big difference between From & To nodes. Specify the support configuration you want somewhere else in your model (e.g., +Y at Node xx). Select that long riser and "Break" it into yy elements and copy the restraint at xx to all new nodes.

Thank you very much sir,

Vertical pipe Clamp support means +Y support right,
150 meter vertical pipe required any anchor for tem. 46 degree C installation and 5 degree C is design
expansion is less only, if we provide any anchor at mid point with all other support are +Y means the anchor loads are huge arround 130 tons,

Kindly advice me how to solve this problem

Dear sir,

Kindly advice me if I provide +Y support at first level means it is working properly and other level of +Y supports are not resting on the on +Y....

So What I have to do for this problem, how to solve this kind of problem.

Dear,

As in any pipe system, you have to support the pipe and guide it. As stress analyst, you decide where to suppot (+Y), where to support and guide (+y & GUIDE) or where only guide.

Your supports must properly work for your load cases, and if you have big loads in your vertical pipe run and you consider you have to reduce it, maybe spring is required.

Study the pipe system and give proper suppurting based on your stress criterion.

Regards.

Spring supports would be an obvious choice.
