Thread design for tubular members

[Kuda]

Hi people
new to this forum but i need some help on my thread design. I've been browsing the net for some time to try and find some help on the design of this but have not found much.

My problem is i have a tubular member of 250mm outer and 100mm inner diameters that is subjected to an axial load of around 157 kN, this load is cyclic and occurs in only one direction so i figured a buttress thread is probs the best selection. This member needs to be fastened to an outer structure but i am having trouble finding the resources needed to design such a thread. The maximum threaded length is about 250mm and i am looking at stainless steels but materials is not really my major concern at this time.

Any help will be appreciated

Have you tried analyzing any designs using CAD software, hand-calculations, ANSYS, etc?

If you can't find any resources I would just try to analyze the bolts' cross-section by hand and find the stresses on the teeth of the thread. Have you checked any libraries for books on thread types?
