What is a structural failure?

Structural failure occurs when a structure, such as a building, collapse or physically fails in a similar way. There are many causes of structural failure, both natural and humans. In some cases, the design or actual construction of the building of fault may be, while in other cases it is the cause of negligence, overload or natural disaster. Sensors and mathematical models are used in the design and maintenance of buildings to reduce and monitor the possibility of structural failure. The factors of possible stress include the shape and the intended use of the building-for example, the height office building is physically different from a multi-level parking garage or a single-storey residential house. Each of these buildings will respond to heavy costs, wind, rain and earthquake in a different way.

The material is also important. For example, steel frames and a large amount of building glass used in skyscrapers give these high buildings the flexibility necessary to withstand high wind strength. Culminated shingledThe roofs on the houses in cold climate allow snow, rather than accumulate during heavy loads and weight formation that could lead to the collapse of the roof - a common type of structural failure. In the case of an earthquake, brick buildings may be more dangerous, although less susceptible to fire than wood buildings, because heavy masonry can collapse and create dangerous danger to those inside.

Structural failure may occur as a result of a design defect if those who designed the building did not take into account its location, shape and intended use. This may also occur due to negligence or building abuse - for example, it is loaded through the intended capacity with people or in addition to items such as machinery. These cases of building collapse are created by man and can be prevented by modeling probable tribes on the building mathematically during the design process and following these instructions on the life of the building.

natural disasters and weather phenomena can often be more demandingthreat. Strong winds, fire, rain or snow weight and earthquakes can lead to structural failure. Although these factors are expected to design and construction as much as possible, there are still accidents. Unexpected corrosion of the metal frame element due to water leakage can lead to the collapse of the structure. Errors in concrete mixtures used to build foundations can lead to cracking and possible failure.

In order to alleviate these risks, engineers often use sensor systems mounted inside the structure. Vibration devices called accelerometers can measure and are used to measure bridge function. The meters and optics of the fiber use to detect voltage and damage caused by load on structures. These and other related sensor devices help engineers predict and prevent possible structural failure.
