H section steel is a kind of cross section area allocation optimization and weight more reasonable than the economic section of effective profile. Since the different parts of h-beam with orthogonal configuration, so h-beam in all directions has bending capacity, simple construction, cost saving and structure light weight etc, so today we’re going to talk about h-beam in building what advantage?
H section steel structure, light weight, covers an area of small, compared with concrete structure dead weight is light, reduce weight, reduce the internal structure design, can make the building structure based processing demand is low, construction is simple, the cost is reduced. And is suitable for all-weather construction, influenced by the climate conditions. Is given priority to with hot-rolled h-beam steel structure, not only because of its scientific and reasonable structure, good plasticity and toughness, high structure stability, applicable to withstand vibration and impact load large building structure, strong ability to resist natural disasters, especially suitable for some more earthquake belt structure; And the construction speed of about two to three times the speed of the concrete structure construction, capital turnover doubled, reduce financial expenses, saving investment.
According to statistics, in the above magnitude 7’s devastating earthquake disasters in the world, predominantly h-beam steel structure building victims is minimized. Increase the structure effective use area. Compared with concrete structure, steel structure column cross-section area is small, which can increase the building effective use area, depending on architectural form, can increase effective use area of 4-6% compared with the welded h-beam, can significantly save work material, reduce the consumption of raw materials, energy and artificial, low residual stress, surface appearance and good quality.
