The key of efficiency of composite construction over the other Constructions can be expressed in a simple way. Steel has merits of high strength, gas/water tightness, longevity, and industrialized construction. One example of the flat roof type can be seen in the next picture, where the secondary timber beams span between the primary beams. For example, if a beam is being designed, the design values used will typically be bending, shear and compression perpendicular to the grain and modulus (to calculate deflection). The analysis also accounts for notches at the supports, which can impact the structural integrity of the beam. The total load Timber beams are used in many buildings, warehouses and garages.
