Design of Built-Up Laced Column
The design of a built-up laced column to support an axial load involves several steps. Below is a structured approach to designing a built-up laced column with the given parameters.
Parameters
- Load (P): 900 kN
- Length (L): 12 m
- Material: Fe 410 Steel
- End Conditions: Held in position and restrained against rotation
Step 1: Column Sizing
- Select a suitable angle size for the column. A common choice is to use angles of equal size, such as 100 mm x 100 mm x 10 mm.
- Calculate the effective length (Le) using Le = L (for fixed ends, Le = L).
Step 2: Determine the Slenderness Ratio
- Calculate the radius of gyration (r) using the formula: r = √(I/A), where I is the moment of inertia and A is the cross-sectional area.
- Calculate the slenderness ratio (λ) using λ = Le/r.
Step 3: Load Carrying Capacity
- Determine the buckling load (Pcr) using the Euler's formula: Pcr = π²EI/Le².
- E is the modulus of elasticity for Fe 410, approximately 200 GPa.
Step 4: Design Lacing System
- Design the lacing system to ensure stability. The lacing can be done using flat bars at a specified angle (usually 45 degrees) to ensure effective load transfer.
- Use appropriate lacing spacing as per design codes.
Step 5: Check for Local Buckling
- Ensure that the design meets local buckling criteria based on the width-to-thickness ratios of the angles used.
Final Considerations
- Verify safety factors and consider factors of safety as per relevant design codes.
- Perform a detailed check for shear and bending stresses to ensure the column can safely support the axial load.
This structured approach should enable the effective design of a built-up laced column to support the specified axial load.
