### Longitudinal and Shear Reinforcement Calculation for a Column
**Problem Statement:**
Determine the longitudinal and shear reinforcement for a 275 mm square, short-braced column which supports an ultimate axial load of 1280 kN and a moment of 62.5 kNm about the x–x axis.
**Design Data:**
- **Durability:** Moderate
- **Fire resistance:** 1 hour
- **Density of concrete:** 25 kN/m³
- **Characteristic strength of concrete (fₚcu):** 35 N/mm²
- **Yield strength of steel (fᵧ):** 460 N/mm²
- **Assume diameter of main steel bars:** 20 mm
**References:**
Refer to sheets 1, 5, and 6 of the extracts provided for further data and formulae.
