Course objectives: Increased knowledge of the design and construction of prestressed concrete structures. The skills necessary to analyze, design and construct of prestressed objects. The skills to identify the issues related to the design and construction of prestressed structures.
Course content: Idea of prestressed structures. History of prestressed structures. Comparison of prestressed structures and reinforced concrete structures. Properties of concrete for prestressed structures and prestressing reinforcement. Technology of prestressed concrete (pre-tenstioned and post-tensioned elements). Grout. Losses of prestress. Effects of prestressing on concrete elements and structures, design of prestressing. Limitation of stress due to service load, limiting zone for the location of the tendons. Cross-section forming. Crack resistance. Limiting zone for the pressure line. Ultimate resistance of elements subjected to axial force and bending moment. Elements subjected to shear. Analysis of the anchorage zone. Stress in the anchorage zone. Calculation model and check of zones under anchors. Reinforcement of the anchorage zone. Serviceability Limit State. Crack control. Deflection control. Examples of civil engineering prestressed structures.
