Analytical Design Review of SP-38(S&T); Handbook for Typified Designs for Structures with Steel Roof Trusses

The paper studies the designs of steel roof trusses under the effect of wind forces, illustrated in SP: 38–1987, which is a handbook for typified designs of structures with steel roof trusses. The review has been done as a comparative study, which compares the illustrated designs of SP 38 with the designs of the same trusses, taking the provisions of IS 875–1987(Part-III) into design considerations. The paper attempts to explore the scope of improvization of the handbook by updating the current designs and incorporating the revised factors (class of structure terrain specifications, permeability factor, height, and structure size) of wind force analysis as per IS 875 to create effective designs of steel trusses or industrial shed structures, providing these designs with updated provisions.
