We often are asked, “How big are the posts in your buildings?” People are often surprised (and sometimes annoyed) when we tell them we don’t know. Each building is engineered individually and the post size is determined based on a number of different factors. Additionally, the strength of our buildings does not lie in the size of the post. Our buildings, although they are pole buildings, are engineered using the diaphragm design method. What this means is that the wind load is dispersed through the building as a whole using the strength and stiffness of the entire building including trusses, wall framing and sheathing to transfer lateral loads to the foundation. What this means to you is that that the building is designed to look good for a very long time because the building moves as one and does not take all the load in the posts which can result in a disfigured building down the road.
When principles of diaphragm design are not applied, the total lateral wind load must be withstood solely by the posts. When the post takes the whole windload, the need to be bigger! (Not necessarily better!).
