RE: Anchor Forces & Moments

Hi Tushar Zope

your question is one of transfer of responsibility. The pipe stress engineer calculates the forces and moments generated by the pipe system which need to be resisted by a structure. It is the job of the structural engineer to provide supports capable of withstanding these forces and moments. In my opinion, it is important that the pipe stress engineer understands a little about the design of the supports, and conversely, the structural engineer understands a little about the pipe force/moment design. Without this overlap of understanding, it is all too easy to produce an inefficient overall design. Also without overlap, it is easy to make mistakes, especially through misunderstanding. On a project with a designated lead designer, it is his/her responsibility to ensure overall design efficiency/ cost effectiveness. Your first task is to find out who this person is. This person should be able to answer your question, or tell you who to ask. If your project is management style based, it may be necessary to build a relationship with the structural engineers. You will probably find that the answer to your question is at least as complex (and probably more) as your calculations required to determine the applied forces and moments. There is no easy answer, but you will increase your value immeasurably if you attain a basic understanding of the design principles of structural restraining systems.
As a starting point, I suggest you read "Structural Steel Simply Explained" by Oscar Faber. Then read everything you can find by Oscar, including "Reinforced Concrete Simply Explained". His books are short and to the point. They will help you inderstand what the structural engineers are trying to tell you. I wish I knew a book you could give the structural engineers to read. I have not found one yet.

Cheers

Subject: [PipingDesign] Anchor Forces & Moments

Friends,

In one of our projects, Anchor forces & moments is the cause of arguments & discussions of the experts.

How do we check that the anchor forces & moments are with in the allowable limits? I mean the anchor itself does not fail.

Is there any formula to check the strength of the anchor? In this case how to
calculate the allowable value for (Fx, Fy, Fz & Mx, My, Mz).

Thanks & regards.
