Angle may use as single angle or double angles and the connection may be bolted or welded. Most of the design provisions for hot- rolled tension members are available and only few studies were reported in literature regarding behavior of cold formed steel bolted angle tension members.The main objective of this study is to investigate the behavior of cold steel single and double angle subjected to tension. Experimental, theoretical investigations were carried out for single angle, double angle connected to opposite sides of gusset plates and double angle connected to same side of gusset plates.

Typical examples includes building and non-building structure ones such as bridges and dams. Some structures are temporary, built for some events such as trade shows, conferences or theatre, and often dismantled after use. Temporary structures have fewer constraints relating to future use and durability. Some structures are permanent. 1.2 TRUSSES Truss is a structure, comprising one or more triangular units constructed with straight members whose ends are connected at joints referred to the nodes. External forces and reactions to those forces are considered to at only at the nodes and results in forces in the members which are either tensile or compressive force. A planar truss is one where all the members and nodes lie within a two dimensional plane, while a space truss has members and nodes extending into three dimensions. Figure 1.1. Planar Truss
