Non-straight Beams: Frames & Arches

This lecture covers the analysis of non-straight beams, frames, and arches, focusing on matching conditions, internal load diagrams, and stress resultants. The instructor explains the integration process to determine internal load distributions and emphasizes the importance of boundary conditions. The lecture also delves into the concept of concentrated forces and couples, providing guidelines for calculating reactions. Additionally, the lecture discusses the application of stress resultants in frames and arches, highlighting their limitations and specific conditions for validity. The examples presented illustrate the calculation of reactions and internal load diagrams for non-straight beams and circular arches.
