The chapter finally discusses various problems regarding the concepts discussed, which are helpful for the readers to understand these concepts. This makes it possible to minimize the dimensions of the cross sections of the structures. The study of influence lines allows the designer to highlight the position of the force that can be applied, leading to extreme stresses. This is an undergraduate course on Structural Analysis, with 39 video lectures and 2 supplemental problem videos. Course Introduction & Overview Classification of Structures & Support Reactions Support Reactions contd. The response obtained gives the support reaction and/or internal action, which describes the influence line. Influence Lines & Moving Loads - Example Problems.
The influence lines of support reactions and/or internal actions can be established by applying a moving unit action.
The influence lines of support reactions and/or internal actions can be deduced by using one of the statically indeterminate structural analysis methods: the method of three moments, the slope-deflection method, the method of forces or the moment-distribution method.
This chapter discusses different statically indeterminate structural analysis methods to study the influence lines of beams, frames and truss structures.
