Description

Method for joining prefabricated columns and composite beams using deck beams The present invention relates to a method for joining a pre-assembled column and a composite beam using a deck beam, and more specifically, to a method for joining a pre-assembled column and a composite beam using a deck beam that can improve the joining performance of the pre-assembled column and the composite beam. In conventional architectural structures, single structures using the same material for columns and beams, such as reinforced concrete, steel, or steel-reinforced concrete structures, are generally used, and these single structures have been systematized while forming specialized fields. Among these, reinforced concrete structures are the most widely used structurally and economically, as they are designed to complement concrete—which is strong in compression but very weak in tension—by reinforcing it with steel, which is strong in tensile strength. However, despite their various advantages, reinforced concrete structures have disadvantages, such as large cross-sections and weights of members, a long construction period required because concrete must be poured and cured according to the progress of the construction, and the need for thorough management due to the difficulty of achieving uniform construction. In addition, steel structures are made of steel, which has superior strength and ductility compared to reinforced concrete, and thus can absorb a large amount of deformation energy caused by earthquakes, wind, impacts, etc., making them advantageous for high-rise or super high-rise buildings or long-span buildings. However, they have disadvantages such as members being prone to buckling under compressive force, strength reduction or deformation due to high temperatures during welded connections, and rust due to moisture. However, recently, as buildings have become larger and taller in terms of scale and more complex and diversified in terms of function, a single structure as described above is unsuitable for building requirements due to the characteristics of its materials, and disadvantages have arisen in terms of construction conditions and economics. Such a building structure has the problem of increasing construction time and costs because it reinforces both columns and beams rather than just the ends weak to shear force.
