Fundamentals of Structural Analysis Concepts

Structural analysis is the process of determining the behavior of a structure under various loads and conditions. The basic principles of structural analysis include:

Equilibrium: The forces acting on a structure must be balanced in order for it to be stable.
Compatibility: The deformations of a structure must be compatible with the loads applied to it.
Constitutive laws: The material properties of a structure must be known in order to determine its behavior under load.

The different types of structural systems include:

Beams: Beams are slender structural elements that are subjected to bending loads.
Frames: Frames are structures that are made up of beams and columns that are connected together.
Trusses: Trusses are structures that are made up of slender members that are connected together in a triangular configuration.
Plates: Plates are thin structural elements that are subjected to in-plane loads.
Shells: Shells are curved structural elements that are subjected to out-of-plane loads.

Methods of Structural Analysis

The various methods used for structural analysis include:

Graphical methods: Graphical methods are used to determine the forces and deflections in a structure by drawing diagrams.
Matrix methods: Matrix methods are used to solve the equations of equilibrium and compatibility for a structure.
Finite element methods: Finite element methods are used to divide a structure into a number of small elements and then solve the equations of equilibrium and compatibility for each element.

The advantages and disadvantages of each method are as follows:

Graphical methods: Graphical methods are simple to use but can only be used for simple structures.
Matrix methods: Matrix methods are more powerful than graphical methods but are more difficult to use.
Finite element methods: Finite element methods are the most powerful of the three methods but are also the most difficult to use.

Structural Modeling and Idealization

The process of creating a structural model for analysis involves:

Defining the geometry of the structure.
Defining the material properties of the structure.
Defining the loads that will be applied to the structure.

The different types of idealizations and simplifications that are commonly used include:

Pin-jointed connections: Pin-jointed connections are used to represent connections between members that are free to rotate relative to each other.
Rigid connections: Rigid connections are used to represent connections between members that are not free to rotate relative to each other.
Continuous beams: Continuous beams are used to represent beams that are supported by more than two supports.
Simply supported beams: Simply supported beams are used to represent beams that are supported by only two supports.

Analysis of Beams and Frames

Beams and frames are subjected to various types of loads, including:

Axial loads: Axial loads are loads that are applied along the axis of a member.
Shear loads: Shear loads are loads that are applied perpendicular to the axis of a member.
Bending loads: Bending loads are loads that are applied to a member that cause it to bend.

The methods used for analyzing beams and frames include:

Shear and moment diagrams: Shear and moment diagrams are used to determine the shear and bending forces in a member.
Deflection analysis: Deflection analysis is used to determine the deflections of a member under load.
Stability analysis: Stability analysis is used to determine the buckling load of a member.

Analysis of Trusses

Trusses are subjected to various types of loads, including:

Point loads: Point loads are loads that are applied at specific points on a truss.
Distributed loads: Distributed loads are loads that are applied over a length of a truss.

The methods used for analyzing trusses include:

Method of joints: The method of joints is used to determine the forces in the members of a truss by considering the equilibrium of each joint.
Method of sections: The method of sections is used to determine the forces in the members of a truss by cutting the truss at a section and considering the equilibrium of the cut members.

Analysis of Plates and Shells

Plates and shells are subjected to various types of loads, including:

In-plane loads: In-plane loads are loads that are applied to a plate or shell in the plane of the plate or shell.
Out-of-plane loads: Out-of-plane loads are loads that are applied to a plate or shell perpendicular to the plane of the plate or shell.

The methods used for analyzing plates and shells include:

Finite element method: The finite element method is used to divide a plate or shell into a number of small elements and then solve the equations of equilibrium and compatibility for each element.
Boundary element method: The boundary element method is used to reduce the size of the problem by only considering the boundary of the plate or shell.

Computer-Aided Structural Analysis

Computer software is widely used for structural analysis. The different types of software available include:

General-purpose finite element software: General-purpose finite element software can be used to analyze a wide variety of structures.
Special-purpose structural analysis software: Special-purpose structural analysis software is designed to analyze specific types of structures, such as bridges or buildings.

The capabilities of structural analysis software include:

Preprocessing: Preprocessing involves creating a structural model of the structure and defining the loads that will be applied to the structure.
Analysis: Analysis involves solving the equations of equilibrium and compatibility for the structural model.
Postprocessing: Postprocessing involves viewing the results of the analysis and generating reports.
