Poles, from which these buildings get their name, are natural shaped or round wooden timbers 4 to 12 inches (100 to 300 mm) in diameter. [4] The structural frame of a pole building is made of tree trunks, utility poles, engineered lumber or chemically pressure-treated squared timbers which may be buried in the ground or anchored to a concrete slab.
Slip gates are a form of gate which permits people and vehicles through an entrance but which blocks the passage of animals. Branches or worked wood crossbars or stangs were used, one field slip gate pier with L-shaped grooves and the opposing stile gatepost with square or circular concavities to receive the three or four horizontal crossbars.
In the U.K. a strut may be very similar to a post but not carry a beam. [8] In wood construction posts normally land on a sill, but in rare types of buildings the post may continue through to the foundation called an interrupted sill or into the ground called earthfast, post in ground, or posthole construction.
A reinforced concrete column is extended by having the steel reinforcing bars protrude a few inches or feet above the top of the concrete, then placing the next level of reinforcing bars to overlap, and pouring the concrete of the next level. A steel column is extended by welding or bolting splice plates on the flanges and webs or walls of the ...
This is a list of building materials.. Many types of building materials are used in the construction industry to create buildings and structures.These categories of materials and products are used by architects and construction project managers to specify the materials and methods used for building projects.
The defects in concrete in Japan were found to be mainly due to high water-cement ratio to increase workability. Poor compaction occurred mostly because of the need for speedy construction in the 1960s and 1970s. Hajime Okamura envisioned the need for concrete which is highly workable and does not rely on the mechanical force for compaction.

The Wood–Armer method is a structural analysis method based on finite element analysis used to design the reinforcement for concrete slabs. [1] This method provides simple equations to design a concrete slab based on the output from a finite element analysis software.
