Depending on the size and the material (solid hardwood or industrial steel), large beams can weigh upwards of a thousand pounds and necessitate a crane to lift and position them. The installation of structural beams-those that are part of a building’s weight-bearing design-is always a job best left to the pros. But timber-frame assembly, also referred to as “post-and-beam construction,” never died out completely-it’s still a feature in ski resorts, mountain homes, cabins, large barns, and agricultural buildings. Exposed beam construction became the norm, appearing in cottages and castles alike throughout Europe, the Orient, the Middle East and virtually all countries as architecture evolved.Īs construction technology advanced in the 1800s and lumber mills capable of the mass production of wood members appeared, massive overhead beams were gradually replaced by the smaller dimensional lumber used to frame rafters (the sloped members) and joists (the horizontal ceiling members) in home construction.įrom the 1950s to the 1980s, high ceilings and large beams were concealed behind lower, “dropped” ceilings during remodels to help reduce heating and cooling bills. With the invention of rudimentary tools, craftsmen could carve longer beams from larger trees. Logs and sticks, the precursors of early beams, were laid across the tops of stone walls. ![]() ![]() Overhead beams are a standard element in timber-frame construction and, while they have an undeniable aesthetic appeal, their earliest purpose was purely functional: Large beams effectively support the weight of upper floors and roofs.
