# Industrial Specification: Column Body

## 1. Technical Definition
The main structural component of a column that provides support and houses internal mechanisms.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150 MPa compressive stress, 0-80°C operating temperature, 0-100 kN axial load**. Failure boundary: **Yield strength threshold at 250 MPa compressive stress, buckling failure at 120 kN axial load with L/r ratio &gt; 200, fatigue failure at 10^7 cycles with stress amplitude &gt; 100 MPa**, Mechanism: **Plastic deformation exceeding yield strength (σ_y = 250 MPa for structural steel), Euler buckling instability at critical load P_cr = (π²EI)/(KL)², high-cycle fatigue crack propagation from stress concentrations at weld joints**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$
