CHECK OF HINGED – BASE CONNECTION STRESSES COLUMN SECTION ( I – SECTIONS ) ACCORDING E.C.O.P.2001

In order to check the stresses in a hinged-base connection of a column section (I-section) according to the European Code of Practice for Steel Structures (ECOP) 2001, you would typically follow a design procedure that includes the following steps:

1. Determine the column loads: Calculate the axial load, bending moments, and shear forces acting on the column. These loads can be obtained from the structural analysis of the entire structure.
2. Select a suitable column section: Based on the column loads and the required design parameters (such as serviceability and strength criteria), select an appropriate I-section for the column.
3. Design the base plate: Design the base plate to resist the applied column loads. This includes calculating the required plate thickness, dimensions, and the number of anchor bolts. The design should consider factors such as uplift forces, shear forces, and moments.
4. Check the base plate connection: Verify the adequacy of the hinged-base connection. This involves checking the stresses in the connection elements, such as anchor bolts and welds, using appropriate design equations from ECOP 2001. The specific equations and design procedures depend on the connection details, bolt type, and load conditions.
5. Check the column section: Evaluate the stresses in the column section itself, including axial stress, bending stress, and shear stress. Ensure that the section can withstand the applied loads without exceeding the design limits specified in ECOP 2001. The section properties, such as moment of inertia and section modulus, are needed for these calculations.
6. Consider stability: Verify the stability of the column by assessing its buckling resistance. This involves checking the slenderness ratio of the column against the limits provided in ECOP 2001.
7. Review the results: Evaluate the calculated stresses and compare them with the allowable limits specified in ECOP 2001. If the stresses are within the permissible range, the hinged-base connection and the column section are considered adequately designed. Otherwise, adjustments may need to be made, such as increasing the section size or modifying the connection details.
