Needs analysis: The first step in the preparation of a Steel Structure Engineers assess the use of the building, anticipated loads, operational areas and future expansion requirements. For instance, a logistics warehouse needs wide-span framing, or a manufacturing plant must be able to hold significantly heavy equipment. These initial choices dictate the base for the whole Steel Structure layout.
The performance of a Steel Structure is highly dependent on its local conditions. Wind, snow and earthquakes, as well as soil pressure and environmental influence must all be layered after detailed inspections. Engineers then work out the loads on a structure—dead, live, dynamic and environmental—and use these to calculate safe dimensions of members for the frame. This will ensure that the Steel Structure is safe and durable for longterm use.
The quality of Steel Structure also depends on the kind of material used. High-strength grades of steel are normally used to achieve the best performance under stress. Depending on project climate and use, coatings resistant to corrosion, treatments for fireproofing and insulation that improves energy efficiency can be incorporated. To match material characteristics with structural requirements and assure that steel structure fits the durability as well as economical targets, or a team of electrical engineers.
After the loads and materials have been determined, engineers “lay out” the general structural system. These are columns, beams, trusses, bracing and roof assemblies. For wide span applications, welded H-beam and portal frames are commonly selected. For buildings of several stories, composite and rigid floors are adapted. Every decision has consequences for the building operation and as such, Steel Structure is one of the key milestone during design process.
Screw connections within any steel frame are frequently the reason for real world functioning. Drawings are developed by engineer’s to define bolts, welds, gusset plates and anchor points so the structure is properly erected in the field. Precision drawings ensure ease in positioning and install-ability of axles. This phase also incorporates BIM Steel modeling, which is commonly used to visualize the Steel Structures and address the potential clashes before it reaches fabrication stage.
One of the big benefits of a Steel Structure is that some components are can be manufactured offsite within factory settings since it limits the amount of assembly even more. All beams, posts and plates are manufactured to ISO and industry standards. Some of the quality tests include testing dimensions, welds and coating adequacy. This procedure is what allows fast and safe installation on site when the Steel Structure arrives.
The last phase is to set up the Steel Structure as per BEAM of Engineering Drawings. Components are put into place by cranes and lifting gear before being bolted and welded into place, supported and braced. Following bitumen roof and wall cladding, walls and roofing are aligned, load path transfer is reviewed with Inspectors in place, safety inspected before the building is 'mudding' completed.
