Numerous readers have requested advice on the quickest, easiest way to build post and beam frames. I suggest using standard galvanized metal wood connectors by companies such as Simpson Strong-Tie. (I’m referencing Simpson anchors because they’re widely available. Shop and compare. All brands meet code.) Deciding which connectors to use can be a bit confusing since there are hundreds to choose from. Post bases on a small porch, for instance, usually don’t need to be as securely anchored in the concrete as a house. For a porch, it’s usually more important to raise the posts to prevent moisture damage, so a different post base may be used than what is shown here. And to add to the challenge of selecting the right ones, connectors go by different names. Wall bracing may be called sway bracing, a post cap may be called a beam anchor and so on. The drawing above shows a typical example. Other similar connectors could be used, but the ones shown here will get you started in the right direction.
Note: Foundation variations include post/pier footings, monolithic slab, standard 8″ wide reinforced concrete foundation with the floor butted up to it, insulated foundations for cold climates (ICFs, rigid foam board, scoria earthbag, shallow frost-protected foundation, etc.).
