Compression in Structures: Cables and Arches

This lecture explores the analogy between cables and arches, focusing on the compression structures. It covers the main characteristics of arches, stability issues, and the difference between hyperstatic and isostatic arches. The lecture also delves into the horizontal thrust at supports and methods to ensure stability. Examples include Renzo Piano's stone arches, the use of earth blocks, and the optimization of arc geometry. The instructor discusses the design considerations for compression structures, such as material selection and the integration of stabilizing elements. The lecture concludes with a detailed analysis of various arch types, including circular arches and their limitations in pure compression.
