A Steel beam is a nominally horizontal element bearing transverse loads, whose primary function is to resist bendin stresses.
They can be distinguished into two types: primary and secondary beams.
– Primary beam. – These beams bear heavier loads and transfer them to the vertical elements. As they need deeper sections, “I” shaped beams are the most common sections used.
– Secondary beam. – They are usually used to transfer the loads from floors, roofs and walls to primary beams or columns. The loads applied to these members are lighter since they are spaced at short intervals.
