17/3/2009 · Traditionally, engineers have designed the structure for high-rise buildings using all structural steel or all structurally reinforced concrete. There are advantages to each building material. "Composite structures" combine the two using structural steel columns and beams for floor construction, concrete on metal deck floors, and a concrete core structure that contains elevators and
An exposed steel structure is proposed with: S355 steel to BS EN 10025-2:2004 the beams welded to the column flange, as shown in Figure 1.1 the elements are hot rolled sections and the thickest parts are 31.4 mm (column flange) and 19.6 mm2

Anchor bolts are used to connect structural and non-structural elements to concrete. The connection can be made by a variety of different components: anchor bolts (also named fasteners), steel plates, or stiffeners. Anchor bolts transfer different types of load: tension forces and shear forces. A connection between structural elements

Steel-concrete composite structures have been used extensively in bridge structures, both highway and railway bridges, due to the benefits of combining the two construction materials, their higher span-to-depth ratio, reduced deflections, and higher stiffness ratios than traditional steel or concrete beam structures (Lin et al., 2016a).).
