Abstract
Pre Engineered Building type of structures are extensively used as industrial structures which consists of channel steel purlins spanned between the rigid frames and also with the wall cladding at sides Pre Engineered Buildings structures which are less height structures are useful for houses, offices, showrooms etc were as conventional structures need longer time for constructing and also costly for larger length spans and also require heavier foundations. In the present work to find the wind effects on pre-engineered buildings Pre Engineered Buildings structures, with x bracings at the ends are considered in analysis of structure having material grade properties Fe250 steel and structure sizes along height is 10m from the foundation or footing top, length of shed is 184m and width of shed is 40m, column to column distance in shed is 8m. Base conditions as pinned base and structures are analyzed using STAAD Pro with wind
velocities 33, 39,44,47,50 and 55m/s as per IS 875-3. It is observed that the structures subjected to higher win velocities are more affected, and also observed that the sections are optimized for bracings and purlins, bracings optimized section is PIP1937L and purlins optimized section ISMC150
