Note the use of high-rise building steel structure large shopping malls, high-rise buildings, bridges, steel structures are used as a framework for the main structure, replacing the traditional reinforced concrete structure. Then the steel construction process, the following points should be noted. Yunnan Steel believes House floor tall steel building should have sufficient rigidity when the earthquake energy can transfer and dispersion, floor beams can be of steel - concrete composite beams or composite beam, floor and the best use of pressed steel composite slab poured on top of a layer of reinforced concrete and steel structures to facilitate speed up construction projects, generally less-situ reinforced concrete floor. Precast reinforced concrete slab stiffness is poor, should not be used in high-rise steel structure, must be used if, in addition to panels and steel beams should be reliable seismic structural connections, should not be less than 4cm above it cast reinforced concrete surface layer thickness combination of steel shear connectors must be used to connect the two materials, one of the connection according to their different points of deformation and rigid connection of flexible connectors, plus when prestressed concrete cast thin layer of prefabricated reinforced concrete When general-situ reinforced concrete floor or slab or other light floor, floor and steel beams should be a reliable connection, in order to ensure the integrity of the floor. Square and T-beam steel and rigid connections, cylinder head studs, channels and bending steel fittings belong flexible connectors, cylinder head studs, channels and bending steel fittings belong flexible connectors, connector commonly used for Cylinder head nail shear connectors, composite beam frame strong earthquake zone, the area should not be set higher than the plastic pegs, to prevent the beam just had a bad general node pull, a strong earthquake area floor to sit at the rate of steel dowel column Squeezing through the column to the floor and, if necessary, steel floor and adjacent parts of the column should be added reinforcement and stirrups. Or adopt other effective measures to enhance the torsional rigidity of the structure. http://www.yntaiyang.com Yunnan Steel | Steel Works Yunnan | Yunnan Steel Design
