Timber framing is a nearly obsolete system for creating the structural skeleton of a house. Timber framing was used in Europe since medieval times, and is the basis for English half-timbered houses where the structural timbers show on the filled and stuccoed exterior. In a timber-frame building, the entire weight is carried by massive beams and posts; wall sheathing is just a curtain to keep out the elements. Timber framing was the basic technique for building wooden houses in the U. The timber frame was hand hewn. In the early days, all of the framing timbers were felled and squared up by hand.
Barns are perfect for studying construction techniques. Unlike in a house, in a barn the structure is out in the open. Everywhere you turn you can see clues to the way in which the building was constructed.

Archaeologists in Germany say they’ve used tree-ring data to identify four ancient water wells as some of the world’s oldest timber constructions. A research team led by the University of Freiburg said the wells excavated at settlements of the first Central European agricultural civilization in the Greater Leipzig region are the oldest known timber constructions in the world, dating to between 5, and 4, B.

Many instances are found, for example, in ruins of houses in the Silk Road kingdom of Cadota, dating from the first to the fourth century BC. In traditional Chinese architecture, wood components, such as beams, brackets, roof frames and struts, were made to interlock with perfect fit, without using fasteners or glues, enabling the wood to expand and contract according to humidity.
Archaeological evidence from Chinese sites shows that, by the end of the Neolithic, mortise-and-tenon joinery was employed in Chinese construction. The thirty sarsen stones of Stonehenge were dressed and fashioned with mortise-and-tenon joints before they were erected between and BC. The word mortise is derived from the same Latin stem as are the words mortem, mortify, etc.
It is supposed that the usual shape of the mortise resembling the shape of the grave gave rise to the origin of the name. Thus the mortise is the hole in one piece of wood into which the tenon fits. The word tenon is derived from the Latin teno, to hold. From the same Latin stem words as tenacity, tentacle, etc. The tenon is the part of a joint of wood which fits into the mortise.
The Different Types of Timber Joints Explained: Know Which Woodworking Joint to Use When
If you have ever been to Europe, most likely, you also visited a hundreds of years old castle dating back to the Middle Ages. All those turrets and high walls took your breath away and, duly impressed, you retired for some refreshments to the local pub down Castle Street. As you were writing your postcards and chatting away with your fellow tourists about the magnificence of the ancient architecture, little did you know you were, in fact, sitting under the roof of one!
In fact, these buildings might be just as old as the nearby castles and churches, but instead of dominating the landscape, they mold into it. Even though their roofs might have burned down in constant skirmishes between feudal overlords, or their walls destroyed in an explosion during one of the World Wars, their joints were hand carved and fitted to last.
The history of timber framing is long and varied, and spans all the continents of the during one of the World Wars, their joints were hand carved and fitted to last. is believed to be the oldest timber frame construction in the world dating back.

The History of Timber Framing Around the World
The paper presents the results of an experimental investigation of stop-splayed scarf joints, which was carried out as part of a research programme at the Wroclaw University of Science and Technology. Analyses and studies of scarf and splice joints in bent elements presented in the literature are reviewed, along with selected examples of analyses and research on tensile joints. It is worth noting that the authors in practically all the cited literature draw attention to the need for further research in this area.
Load-deflection plots were obtained for load-bearing to bending of each beam in relation to the load-bearing of a continuous reference beam.

For the last few thousand years it can have a precision of a few decades and may, in certain circumstances, be comparable with tree-ring dates. The laboratory at Cambridge here in England was among the first six to be set up anywhere in the world. There are now several radiocarbon dating laboratories in Britain including those at Belfast, Cambridge, East Kilbride, Oxford and Swansea, as well as a commercial unit near Harwell.
Radiocarbon dating is based on the element carbon, the basis of all life on earth. The atoms of this element are of three different types or ‘isotopes’. They are identical chemically but have slightly different physical properties, particularly in mass. The isotopes are respectively 12, 13 and 14 times as heavy as the common hydrogen atom the base unit by which the weight of other elements is measured.
The isotopes C and C are stable and make up the bulk of the element, but the C isotope, which is mildly radioactive, is extremely rare. The instability of radiocarbon results in half of it disappearing in 5, years its ‘half-life’.
Timber Frame in History
Why Do Timber Frames Fail? The fundamental question as to why are ironwork repairs important enough to warrant study can be answered reasonably simply. Iron-work repairs represent the pinnacle of low-tech, minimum intervention repairs to failed timber joints and thus they highlight the inherent failings of the timber, its fabric, construction and properties and the efforts that the craftsmen went to in overcoming its failings.
There are several reasons why timber frames fail and these are summarised following. Given the diversity of joints in timber framing and their steady evolution as highlighted by Cecil Hewett in English Historic Carpentry it is evident that some joints served their purpose better than others. Unsatisfactory jointing techniques were abandoned or rapidly reconfigured to function satisfactorily.
Over time these scarf joints became more sophisticated. The late Cecil Hewett developed a method of dating the timber framed barns of the south-east by the.

Traditional Timber Framing – A Brief Introduction
Made with Xara. The dominating house type was the X-joint log house knuttimmerhus — houses built with horizontally laid logs, interlocked in the corners. Sweden has large woodlands so the conditions were right for constructing log houses. Other terms are notched corners; log built corners or corner joints.
Britain dates to the C13th. The timber of choice in Timber frames and roofs. This leaflet describes the character of historic timber Most joints are based on the.
A mortise occasionally mortice and tenon joint connects two pieces of wood or of material. Woodworkers around the world have used it for thousands of years to join pieces of wood, mainly when the adjoining pieces connect at right angles. Mortise and tenon joints are strong and stable joints that can be used in many projects. The mortise and tenon joint is considered to be one of the strongest joints next to the common dovetail joint. The mortise and tenon tenon joint also gives an attractive lookout.
One drawback to this joint is the difficulty in making it due to the precise and tight cutting required. In its most basic form, a mortise and tenon joint is both simple and strong. There are many variations of this type of joint, but the basic mortise and tenon comprises two components:. The tenon, formed on the end of a member generally referred to as a rail, fits into a square or rectangular hole cut into the other, corresponding member.
The tenon is cut to fit the mortise hole exactly. It usually has shoulders that seat when the joint fully enters the mortise hole. The joint may be glued, pinned, or wedged to lock it in place.

Building a timber frame structure means participating in a longstanding architectural tradition. Found in archaeological sites in the Middle East, Europe, and Asia, timber framing has a history throughout the world. The joints used to construct timber frame structures appeared as early as BC. Prior to timber framing in the United States, many other cultures worldwide capitalized on this building method. Japanese builders also discovered the strength and dependability of working with wooden joints and fibrous timbers.
In an area prone to typhoons and earthquakes, stone buildings would crack under stress, while the timbers shrugged and bore the weight. Modern timber framing has capitalized on technology, using industrial mill processing to speed up the production and reduce costs. However, before the advent of the industrial mill, timber framing was a solely handcrafted process from the ground up. Diaries of early Americans in New England describe the culture surrounding timber framing as one of community-driven labor.
Farmers in need of a new barn would spend the winter gathering wood, and the spring preparing the wood for a master timber framer. In this way, barns and town halls were constructed relatively quickly with the help of fellow citizens. Timber framing was one of the major building models in the United States until the early s when the industrial revolution met the demand for housing by producing smaller, dimensional lumber from its new mills.
