Calculating if a Stack support for a chimney will fail?

helsbay

Hello,
I have a problem in calculating if a support structure for a chimney will fail. I am not asking for someone to do it for me just point me in the correct dirrection. Its the weight and force from the chimney and the external forces like wind that need taking into account. I have used a wind speed of 100mph on the chimney calcs. I have included a pdf of the stack and support of a stucture I know will fail from another companies calcs but I do not know how they did it. Any help will be appreciated and I will be forever in your debt. Thank you.

Rob
