The company was founded by Barclay Simpson in Oakland in 1956, as a successor to his father's window screen company. [1] Simpson manufactured joist hangers and the company's subsidiary Simpson Strong-Tie Co. Inc. became a dominant producer of structural connectors in North America and Europe. [1]

A hurricane tie used to fasten a rafter to a stud. A tie, strap, tie rod, eyebar, guy-wire, suspension cables, or wire ropes, are examples of linear structural components designed to resist tension. [1] It is the opposite of a strut or column, which is designed to resist compression. Ties may be made of any tension resisting material.
A tie rod or tie bar (also known as a hanger rod if vertical) is a slender structural unit used as a tie and (in most applications) capable of carrying tensile loads only. It is any rod or bar-shaped structural member designed to prevent the separation of two parts, as in a vehicle. Tie rods and anchor plates in the ruins of Coventry Cathedral
The discovery of all possible ways to tie a tie depends on a mathematical formulation of the act of tying a tie. In their papers (which are technical) and book (which is for a lay audience, apart from an appendix), the authors show that necktie knots are equivalent to persistent random walks on a triangular lattice, with some constraints on how the walks begin and end.
A cable tie (also known as a hose tie, panduit [1], tie wrap, wire tie, zap-straps, or zip tie) is a type of fastener for holding items together, primarily electrical cables and wires. Because of their low cost, ease of use, and binding strength, cable ties are ubiquitous, finding use in a wide range of other applications.
There is a potential with beginners to wrongly tie the bowline. This faulty knot stems from an incorrect first step while tying the rabbit hole. If the loop is made backwards so that the working end of the rope is on the bottom, the resulting knot will be the Eskimo bowline , looking like a sideways bowline, which is also a stable knot.
Upon installation, tiebacks are tested and usually pre-loaded. In specific, a combination of proof tests and performance tests are performed on every job. Proof testing involves the application of successively larger loads on the tieback with a loading jack, allowing for the recording of a load-elongation curve according to gauge readings.
