Structural Analysis: Deflection in Floor Slabs

This lecture focuses on the analysis of deflections in floor slabs, emphasizing the importance of understanding various load categories and their impact on structural integrity. The instructor discusses coefficients of reduction for different building categories, including residential and commercial spaces, and how these coefficients affect the design and safety of structures. Key concepts such as serviceability limits, ultimate limits, and the significance of deflection limits are thoroughly explained. The lecture also covers the methodologies for calculating deflections, including the use of finite element methods and the importance of adhering to standards like SIA 262. The instructor highlights the practical implications of deflections on construction practices, including the need for careful consideration of material properties and load conditions. Additionally, the lecture addresses the role of deflection in the overall performance of structures, ensuring that they meet both safety and comfort requirements for occupants. Overall, this lecture provides a comprehensive overview of the critical aspects of deflection in civil engineering.
