Most barns were constructed with wooden frames (also known as poles and beams) that formed very strong structures that could withstand severe storms and heavy feed loads. Timber truss is a method of making frame structures out of heavy wood connected by various joints.

Stables often work in 10×12 frames for indoor stables, cab rooms, and sinks. Storing hay in the attic creates its challenges. Years ago people would simply mount summer beams and logs and throw as much straw as possible on the ceiling.
Like most technical things, hay bales are now packed more compactly and weigh more than a few years ago, as are all changes in building code. Nowadays it is common to design attics to withstand loads of 100 pounds per square foot.
Real wood frames are an art that can be traced back several generations. Even today, much of the work is done by hand using traditional tools such as chisels, hammers, and beetles. Pieces of wood, bars, plates, and rods are connected by precise, interlocking connections made of nails and wooden pins.
Various types of joints are used during the construction process. Today most of the wood frame structures are designed to use new CAD (Computer-Aided Design) technology which helps them to properly design and distribute loads.
