Effect of Pitch on the Design of Pre Engineered Building Shed Structure - A Review

Pre-Engineered Steel Buildings uses a combination of built-up sections, hot rolled sections and cold formed elements which provide the basic steel frame work with a choice of single skin sheeting with added insulation or insulated sandwich panels for roofing and wall cladding. The concept is designed to provide a complete building envelope system which is air tight, energy efficient, optimum in weight and cost. These Pre-Engineered Steel Buildings can be fitted with different structural accessories including mezzanine floors, canopies, interior partitions, crane systems etc. The building is made water-tight by use of special mastic beads, filler strips and trims. For pre-engineering steel building apart from conventional structural sections such as angle, Tee, I sections etc. Other tubular and box section are also in vogue presently. For large span industrial structure a parametric study is done taking conventional tubular and box rectangular sections in the present work. The effect of rise to span ratio, its effect on cost is studied.
