TENSION MEMBERS OF NET SECTION EFFICIENCY ON COLD FORMED STEEL ANGLE SECTIONS

Civil Engineering

A tension part is connected by bolts to other parts or gusset plates. The sectional area is reduced by the bolt holes. These holes cause stress concentration adjacent to bolt holes. The stresses at these locations can be a high average stress on the net area at the angle sections. Due to the inherent ductility of cold formed steel this is usually neglected due to stress. The maximum elastic stress ratio adjacent to the hole to the average net cross section stress is referred to as the stress concentration factor Tests. This research work deals with the details of an Experimental investigation and net section failure on cold-formed steel section subjected to tension. This analysis carries single angle sections and double angles sections of 1.5mm and 1.6mm under plain (without Lipped) and with Lipped conditions subjected to tension. Analyses were carried out for 24 specimens of single angle sections and 48 specimens of double angles were connected same side to gusset plate and connected to opposite side. Results were recorded as the net section efficiency of the specimens failed by net section rupture.
