What is the value of the effective depth of a T-beam for heavy loads?

The effective depth of a T-beam for heavy loads is crucial for ensuring adequate strength and stability. Typically, a larger effective depth increases the beam's moment of inertia, allowing it to better resist bending and shear forces. For heavy loads, the effective depth is often optimized based on factors such as span length, load conditions, and material properties, usually falling in the range of 0.5 to 0.75 times the span length. Ultimately, the specific value should be determined through structural analysis and design codes to ensure safety and performance.
