Study on the Design of a Industrial Peb Building

The project is focused on comparison of cost estimates of industrial buildings based on conventional and pre-engineered steel design using Indian code. Many parameters such as building sizes, environmental loads and yield stress values, deflection limit and design codes affect the design of steel members. Industrial gable building is taken for the project work based on location at Puducherry. The analysis of the structure was done using STAAD-PRO software and manual design of the members was carried out as per Indian standards. Portal frame, brace, roof purlins & wall girts analyzed and designed as per Conventional and Pre-Engineered Building concepts. Loads are calculated in accordance with Indian codes. For pre-engineered buildings, cold formed sections are used. Bill of materials is calculated and cost estimates are taken for comparative study. The analytical study revealed the better performance of Pre-Engineered Building than the Conventional Steel Building (CSB) both in design and cost. In PEB, due to the reduction in steel, the dead load is reduced. In PEB the dead load is small which will eventually reduce the foundation size and hence the cost of foundation is reduced. The diagonal bracing for the PEB design offers more feasibility and structural safety as it resists the horizontal forces, which causes sway and deformation in the structure. Therefore, PEB is more advantageous than CSB and can be used for greater spans.
