As this is your first visit to this site, we have no experience of your competence or your ability to successfully carry out this design. This site is for exchange of information between design professionals, and if you were a practicing structural engineer, you would not be asking this question. Please seek assistance from a structural engineer in the real world rather than on-line.

Dear hokie66
when I joined this forum " engineering-tips", I was unaware it was restricted to practicing professionals only. My thought was every professional can join, including EIT's. I respect your opinion and I will seek assistance somewhere else.
