Does anyone have experience designing a building (boathouse) supported on flotation, i.e. a dock. The boathouse will be located on a lake and is approximately 54'-0" x 36'-0". There are three boat slips with roll up doors on the long side of the boathouse.
The building loads will be transferred to the flotation through columns spaced throughout the interior of the boathouse to distribute the load to the flotation as evenly as possible. The boathouse will not be finished on the interior. The exterior walls will be sheathed with plywood and the roof will be skip sheathed and covered with wood shingles.
1. I'm concerned about building movement when subjected to wave action. How stiff or flexible should the building be so that it can withstand the cyclic nature of the wave action?
2. I'm also concerned about the side of the building that has the roll up doors, and in particular the two short walls that separate the three doors. Could there be a load case during extreme weather when the short walls and tributary roof loads are not supported on the column and flotation but rather the flotation and column are hanging from these walls?
If anyone has comments or insights they would be appreciated.
Thank you...
