This is most effective book for students and professionals who pursue study and practices in Structural Engineering. The theory and Problems links with practical approaches and real engineering judgements.
American Society for Civil Engineer (ASCE) has published the latest version (ASCE 7-22) for Minimum Design Load and Associated Criteria for Building and Other Structure describes the means for determining design loads including dead, live, soil, flood, tsunami, snow, rain, atmospheric ice, seismic, and wind loads and their combinations for general structural design. Structural engineers, architects, and building code officials will find the structural load requirements essential to their practice.

It is a method or tool by which we find out how a structure or a member of a structure behaves when subjected to certain loads.
In other words finding out internal forces (axial force, shear force, moment), stress, strain, deflection etc in a structure under applied load conditions.
Whenever design any structure first of all we Analyze the structure either manually or through software or may be both. So there is number of methods of Structural Analysis. Mainly these methods are used to analyze indeterminate structures ( no. of reactions more than equilibrium equations) In this article we will discuss just the name of methods.
Methods of Analysis
There are two main Methods which have further divided into different methods. There is some limitations while analysing any structure that’s why you have to chose the most appropriate method while analysing any structure.
(1) Exact Methods
It is the most accurate methods while analyzing any indeterminate structures. It is also called accurate method. In this method the material property called Modulus of Elasticity (E) and geometric property called Area Moment of Inertia (I) of the materials are required.
This method is further subdivided into two methods. We will discuss each methods in detail in the next article.
1. Force Methods
Three Moment Theorem
Virtual Work/Unit Load Method
Strain Energy Method
Methods of Consistent deformation
Minimum Potential Energy Method
Castigliano’s Method etc
2. Displacement Methods
Moment Distribution Method
Stiffness Matrix Method
Slope Deflection Method
Kani’s Method etc
(2) Approximate Methods
In this method the material property called Modulus of Elasticity (E) and geometric property called Moment of Inertia (I) of the materials are not required. In this method indeterminate structures first convert to determinate structures and then analysed using equation of equilibrium.
The following three methods normally used in analysing.
