The document presents a detailed analysis of a grillage model for calculating prestressing losses and live load effects on structural elements. It includes various load cases and their corresponding cantilever and middle span moments, shear forces, and axial forces for sections with and without structures. The results indicate the maximum bending moments and shear forces under different loading scenarios, providing essential data for structural evaluation.
