It is interesting to note that post and beam construction is still fairly common in the US. Just not for residential buildings. It is used extensively for agricultural barns and commercial and light industrial buildings particularly in rural areas. Often buildings that have sheet metal exteriors are "post framed". Post framing is quite similar to post and beam. A "mortise and tenon" connection is implemented for securing the roof trusses to the posts. On site laminated 2x material is used or a notch is cut in post.
