Beams Design and Dimensioning: Structural Safety and Deflection Analysis

This lecture covers the design and dimensioning of beams, focusing on structural safety and deflection analysis due to permanent actions. Topics include types of sections, static systems, short-term and long-term deflection considerations, and the verification of suitability for service. The lecture also discusses different types of bridges, such as road, railway, and pedestrian bridges, as well as the behavior of materials like reinforced concrete, wood, and steel beams. Additionally, it explores prestressed concrete techniques, including centered and parabolic prestressing, and the post-tensioning process using wires, strands, and bars in sheaths.
