The process of manufacturing wire makes steel stronger (though less ductile), making it possible to create elements with high tension strength but small area and moment of inertia.
to construct with minimal amount of material. After graduation in 1952 Otto began a systematic investigation of suspended roofs. The investigation was presented in the doctoral thesis Das H¨angende Dach (The Suspended Roof), which was the first
This is good and bad.
In a pin-connected chain, such as a bicycle chain, the connections can transfer compression, but the pin connections create a mechanism that is not stable under compression, shear, or moment.

Tension structures must always address the issue of stability, incorporating a strategy to limit changes in shape under varying loads.
in 1953 the arena was completed
A big step in the development of suspended roofs came in 1950 when Matthew
through the architect William Henry Deitrick and civil engineer Fred Severud and
The first structures regarded as cable roofs are four pavilions with hanging roofs
설명
On an exchange visit to the U.S.A. in 1950 a German student in architecture, named Frei Otto, previewed the drawings for the Raleigh Arena in the New York office of Fred Severud. Otto saw that the project embodied many of his own ideas about how
It`s good because the structure will always assume a shape so that it works purely in tension (that`s all it can do), so there is an efficient use of material.
Nowicki designed the State Fair Arena, Figure 2.1, at Raleigh, North Carolina,

Tension structures
The buckling and bending resistance of individual fibers is extremely low compared to the tension strength.
It`s bad because it is usually impractical for a structure to undergo large changes in geometry under varying loads.

It is possible to configure structural elements that have high strength and stiffness in tension, while having low or zero stiffness in compression, bending, and shear.
built in the U.S.A. and Europe, but none of major importance.
The fibers can slip with respect to one another so that the rope does not act as a monolithic unit in resisting buckling or bending.

in 1896. During the 1930’s a small number of roof structures of moderate sizes were
The low moment of inertia gives low resistance to compression buckling and bending.
In a conventional linked chain connections between links transfer no moment or compression, shear cannot transfer across a link.
순서
Since such elements cannot resist compression, bending or shear, they do not maintain their shape (e.g. they are unstable) under changing loads.
