Week 14 (Cables and Arches)
Cables and arches often form the main load-carrying element in many types of structures, and in this lecture we will discuss some of the important aspects related to their structural analysis. The Lecture begins with a general discussion of cables, followed by an analysis of cables subjected to a concentrated load and to a uniform distributed load. Since most arches are statically indeterminate, only the special case of a three-hinged arch will be considered. The analysis of this structure will provide some insight regarding the fundamental behavior of all arched structures.
