CHECK OF HINGED BASE CONNECTIONS BUILT-UP OR ROLLED SECTIONS THE CROSS SECTION IS FULLY EFFECTIVE ACCORDING TO E.C.P. 2001

To check the hinged base connections of built-up or rolled sections where the cross-section is fully effective, you need to follow the relevant design provisions specified in the E.C.P. 2001 (Eurocode for steel structures). Here are the general steps involved in checking such connections:

1. Determine the applied loads: Identify the forces and moments acting on the connection. These loads could include axial forces, shear forces, bending moments, and torsional moments.
2. Analyze the connection: Use structural analysis methods to determine the internal forces and moments within the connection. This analysis should consider the overall structural system and the load distribution.
3. Design the individual components: Determine the required dimensions and properties of the individual components of the connection, such as plates, bolts, welds, etc. This design should ensure that the connection can safely transfer the applied loads while considering factors such as material strength, stability, and fatigue.
4. Check the strength of the components: Verify that the components within the connection, such as plates and bolts, have sufficient strength to resist the applied loads. This involves comparing the applied forces and moments to the capacity of the components.
5. Check the stiffness of the connection: Ensure that the connection has the required stiffness to accommodate the anticipated deformations and rotations within the structure. The stiffness check typically involves examining the deflection and rotation of the connection under the applied loads.
6. Verify stability and robustness: Assess the stability and robustness of the connection to ensure it can withstand accidental actions and unforeseen events, such as impact or overload. This step is crucial for ensuring the overall safety of the structure.
7. Consider detailing requirements: Adhere to the detailing requirements specified in the E.C.P. 2001 for hinged base connections. These requirements may include weld sizes, edge distances, bolt spacing, etc.
