Tension members are structural elements that transmit the axial tensile forces. If tension elements are used together with bolted jointsconnections, yield stress will be reached earlier in the areas where bolt holes are located. This situation will affect the strength determined by using the load-displacement curve.

In bolted and welded joints of tension members, the cross-sectional area operating in load transfer is not equal to the entire cross-section area, as a result of the uneven distribution of the load.
Since the L and U sections are used especially in the corners that are not connected with bolts or weldingwelds, a certain region is called an effective area in the load transfer worksdistribution. The consequence of this partial connection is that the connected element becomes overloaded and the unconnected part is not fully stressed. Due to this phenomenon called the 'Shear Lag' effect, an effective net area is used in the design.

There are 3 different collapse conditions in the elements affected by the tensile force: Yielding Limit State, Rupture Limit State and Block Shear Limit State
The design tensile strength is taken as the minimum strength to be calculated according to the yield limit state, rupture limit state and block shear limit state of the element under axial tensile force. Block shear limit state is an additional check for joints.
Tension The tension element slenderness ratio should be controlled. In accordance with article D1 of the regulation, the slender slenderness ratio should be less than 300.
