The initial creation of textile-reinforced concrete (TRC) began in the 1980s. Concepts for TRC originated from the Sächsisches Textiforschungs-institut e.V. STFI, a German institute focusing on Textile technology. [10] The first patent for textile-reinforced concrete design, granted in 1982, was for transportation related safety items.
The total recordable incident rate (TRIR) is a measure of occupational safety and health, useful for comparing working conditions in workplaces and industries.It is calculated by combining the actual number of safety incidents and total work hours of all employees with a standard employee group (100 employees working 40 hours a week for 50 weeks a year).
In engineering, a factor of safety (FoS) or safety factor (SF) expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.
The National Highway Traffic Safety Administration (NHTSA) has its Vehicle Research and Test Center (VRTC) on TRC property. TRC is the only North American proving ground with a government research and test center on site. [1] [2]

According to IEC 61508, the SIL concept must be related to the dangerous failure rate of a system, not just its failure rate or the failure rate of a component part, such as the software. Definition of the dangerous failure modes by safety analysis is intrinsic to the proper determination of the failure rate. [citation needed]
Logo of Eurocode 2 An example of a concrete structure. In the Eurocode series of European standards (EN) related to construction, Eurocode 2: Design of concrete structures (abbreviated EN 1992 or, informally, EC 2) specifies technical rules for the design of concrete, reinforced concrete and prestressed concrete structures, using the limit state design philosophy.
