Truss, K4 Factor, Lean to Roof


The aim of the study is to analyse the " lean to roof " type steel truss according to IS 875(part 3):2015 in which cyclone impact factor K4 and area averaging factor Ka, directionality factor Kd , combination factor Kc area introduced. With the likelihood of increasing cyclonic conditions in coastal regions and exceeding of basic wind speeds during cyclone, Anew K4 factor is introduced to check the impact on industrial structures as well as post cyclone importance structures. In this paper an attempt is made to compare the methodology of wind load calculation as per IS 875(part3):1987 and IS 875(part3):2015 for industrial and post cyclonic importance structures. The analysis of steel roof truss is carried out in STAAD Pro software for 9m and 12m span considering roof slope 1 in 3, 1 in 4, and 1 in 5.
