where I is the moment of inertia of the beam cross-section and c is the distance of the top of the beam from the neutral axis (see beam theory for more details). For a beam of cross-sectional area a and height h , the ideal cross-section would have half the area at a distance h / 2 above the cross-section and the other half at a ...
The TSI Rolling Stock (2002/735/EC) has taken over the UIC Gauges definitions defining Kinematic Gauges with a reference profile such that Gauges GA and GB have a height of 4.35 m (14 ft 3 in) (they differ in shape) with Gauge GC rising to 4.70 m (15 ft 5 in) allowing for a width of 3.08 m (10 ft 1 in) of the flat roof.

Double tee structure is an alternative for short to medium spans between 40 and 90 feet (12 and 27 m). There are many standards such as double-tee beam of Texas Department of Transportation and the Northeast Extreme Tee (NEXT) Beam of the Northeast. [8] A benefit of using double tees for bridge replacements is to shorten the construction time.
In the area surrounding the overhead lines it is dangerous to risk interference; e.g. flying kites or balloons, using ladders or operating machinery. Overhead distribution and transmission lines near airfields are often marked on maps, and the lines themselves marked with conspicuous plastic reflectors, to warn pilots of the presence of conductors.
Architects, engineers and builders found it difficult to compare rated capacities and to use fully the economies of steel joist construction. Gable steel joists being erected. Members of the industry began to organize the institute, and in 1928 the first standard specifications were adopted, followed in 1929 by the first load table.
