Steel-concrete composite beams horizontal reinforcement how to set? Everybody Xiaobian in the following for everyone to detail. First, the steel-concrete composite beam cross-sectional dimensions 1. Bending capacity, shear capacity, stiffness requirements Simply supported composite beam high span ratio of 1 / 18-1 / 12, generally take 1/15. Concrete thickness usually take Section height of about 1/3, the general use of 100mm, 120mm, 140mm, 160mm; load particularly large platform structure or bridge structure of concrete thickness can be used 180mm, 200mm or even 300mm. The distance between the top surface of the rib of the steel plate and the top of the concrete slab is not less than 50mm 2. The section height of the steel girder The section height ha of the steel girder should not be 1 / 2.5 of the total height h of the section. Stability, according to "Steel Design Code" set the stiffener requirements. 3. Flange plate structure should meet the requirements of the requirements of the composite beam Beam concrete flange plate structure should meet the requirements of the icon. There pallet, the extension should not be less than hc2 length; no pallet, should outdoor pool fence design
