What is Structural Analysis?Structural Analysis, or Analysis of Structures is a branch of Mechanics of Solids used for predicting the behavior of structures like buildings, bridges, arches, towers, cables, automobiles, aircraft, and marine structures when they are subjected to some forces.What will you gain from this course?This course covers the following:fundamental concepts, static equilibrium, different types of beams, supports, loads, and reactions, truss analysis, shear force and bending moment diagrams, stresses and strains, and columns and struts.Basic Concepts: Outline of Structural Analysis, definition, and scope.Static Equilibrium: Principle of Superposition of Forces, Resolution of Forces, Parallelogram Law of Forces, Lami's Theorem, Equilibrium of a Particle, and Free-body Diagram. Internal Forces, External Forces, and Principle of Transmissibility, Moment of a Force-Concept; Varignon's Theorem and Couple, Resolution of a force into force and couple system of forces.Beams, Supports, and Reactions: Free-body Diagram, Equilibrium, and Conditions of Equilibrium, and determination of support reactions for cantilever beams, simply supported beams and overhanging beams.Analysis of Trusses: Important Definitions, Types of trusses, Assumptions made for force analysis, identification of zero-force member, Easy steps to solve the problems on trusses, Determination of internal forces in the members of trusses by the method of joints and method of section.Shear Force and Bending Moment Diagrams: Important Definitions, Estimation of shear force and bending moment at the salient points of various types of beams subjected to different loading conditions.Stresses and Strains: Simple, compound, and thermal stresses, Types of stresses and strains, Poisson's ratio, Elastic constants, and Principal stresses.Columns and Struts: Important definitions, Types of end conditions, Rankine's formula, and Euler's formula.This course also includes solved numerical examples, interactive quizzes, and assignments/exercises in each section for self-evaluation.The numerical examples are solved in a step-by-step process, explained with clear concepts so that the students will be able to understand without any ambiguity.Also, this course provides downloadable study materials in pdf format for future reference.
