STRUCTURAL ANALYSIS I
AIMS AND OBJECTIVES
This course introduces engineering students to the basic techniques required for
analyzing the majority of structures and the elements of which most structures are
composed, including beams, frames, arches, trusses and cables. It provide methods
also, to compute the deflections of structures.
COURSE CONTENT
Introduction and fundamental concepts in structural analysis. Analysis of trusses,
beams, frames, cables and arches. Stability and determinacy of structures. Analytical
expressions and diagrams. Principles of virtual work. Principle of virtual
displacements. The unit dummy displacement method. Energy Principles. Potential
energy and strain energy in structural systems. Calculations for deflection of structures.

Attendance will be taken at the at random times, and these will be evaluated in awarding
your grades. Students are responsible for daily assignments. Homework will be due at the
beginning of the lecture on the due date, which will be shown on all homework
assignments. NO LATE ASSIGNMENTS WILL BE ACCEPTED !!! Missing
assignments will be given a grade of zero. Do not colloborate in solving assignments. You
may see your submission returned with no grade assigned to it. No make-up for quizzes.

ATTENDANCE AND DEADLINES
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
Loads
2.Analysis
3.3.DesignDesign
4.4.ConstructionConstruction
The design of a structure involves many considerations, among which are 4
major objectives that must be satisfied.
Safety (the structure must carry loads safely)
Economy (the stucture should be economical in material and overall costs)
Utility (the structure must meet the performance requirement)
Beauty (the stucture should have a good performance)

Roller support (allows rotation/translation)
Pin connection (allows rotation)
Fixed joint (allows no rotation/translation)
A beam have a variety of supports.
- roller ( 1-DOF)
- pinned ( 2-DOF)
- fixed ( 3-DOF)
