INTRODUCTION
Mechanics, is the branch of physics concerned with the behaviour of physical bodies when subjected to forces or
displacements, and the subsequent effect of the bodies on their environment.
• Statics - bodies at rest or moving with uniform velocity
• Dynamics - bodies accelerating
• Strength of materials - deformation of bodies under forces.
• Structural Mechanics - focus on behavior of structures under loads.
Structural Analysis is a process by which the structural engineer determines the response of a structure to be specified
loads or actions.
Response :
Magnitude of force development (collapse)
Magnitude of deformation (serviceability)

Structural engineering projects can be divided into 4 stages.
1.1.Planning phasePlanning phase•Material•Structural form •Loads2.Analysis3.3.DesignDesign4.4.ConstructionConstruction
The design of a structure involves many considerations, among which are 4 major objectives that must be satisfied.
1) Safety (the structure must carry loads safely)2) Economy (the stucture should be economical in material and overall costs)3) Utility (the structure must meet the performance requirement)4) Beauty (the stucture should have a good performance)

Therefore, the purpose of structural analysis is to determine the reactions, internal forces reactions, internal forces
and deformationsdeformations at any point of a given structure caused by applied loads and forces.
Types of Structural forms
• Tension and Compression structures
• Flexural beam and frame structures (load carrying is achieved by bending)
• Surface structures (load carrying is by membrane action)

Strength : Ability to withstand a given stress without failure. Depends on type of material and type of force (tension or compression).
Stiffness : Property related to deformation. Stiffer structural elements deform less under the same applied load. Stiffness depends on type of material (E), structural shape, and structural configuration.Two main types; Axial stiffness and Bending stiffness.

A beam can be classified as statically indeterminate
beam, which can not be solved with equilibrium
equations. It requires a compatibility condition.
