 FABRICATION, ERECTION AND HYBRID STRUCTURES FABRICATION: Fabrication is the process used to manufacture steelwork components that will, when assembled and joined, form a complete frame.   The process of steel fabrication involves grinding, welding, cutting, bending, drilling, punching, burning or melting, and other general crafting methods using various  high-quality tools and CNC equipment . The entire steel fabrication process is systematic and requires the utmost planning, precision, and knowledge. Steel fabricators are well aware of all the crucial steps and measures that need to be taken care of in the fabrication process.  Structural steel is usually fabricated to create structures like beams, trusses, hollow sections, angles, and plates. ERECTION : The erection of structural steelwork consists of the assembly of  steel components  into a frame on site. The processes involve lifting and placing components into position, then connecting them together...

Hybrid

  Glass and Steel Construction: Glass with a density comparable to reinforced concrete presents modulus of elasticity almost equal to that of aluminium. Glass is several times weaker in tension than in compression. The fracture pattern of glass is highly dependent on residual stress. Annealed float glass breaks into large fragments whereas fully tempered glass presents high fragmentation and breaks into small pieces which does not affect post-breakage strength. Metal enforced glass beams: Comparing the load-bearing capacity of different glass beams in four configurations of glass strips: layered laminated, laminated segmented and laminated reinforced glass, Veer   has proved that even small amount of steel bonded to tensile side of a glass beam improves the post-breakage performance of the beam significantly. Carbon and glass fibre reinforced glass beams: A carbon fibre strip was bonded to the bottom edge of a glass beam with a structural adhesive. The main role of th...

  Steel fabrication, erection and hybrid construction Fabrication: In fabrication methods such as grinding, welding, cutting, bending, drilling, punching, burning or melting are involved. High quality tools and Computer Numerical Controller equipment is also used. Crucial steps and measures are needed to be done in this process. Structural steel is usually fabricated to create structures like beams, trusses, hollow sections, angles and plates. Structures have to be specifically designed and fabricated before constructing and assembling them together.   Steel erection:   Erection is done with the help of cranes or by jacking and lifting and placing components. Bolted connections are done to keep the components secure and bracing is also done. Structure alignment is essential by checking the column bases to be lined and levelled. The process involves lifting and placing an exact position by connecting together. Connections may be achieved by bolting,...
