This document provides an introduction to structural engineering. It discusses different types of structures such as arched, beam/girder, cable suspended, and planar truss structures. It also describes the internal forces of compression, tension, torsion, and shear that act on structures. External forces include static loads like the weight of a structure and dynamic loads such as wind. Structural engineering designs and builds structures like buildings, bridges and frameworks to safely withstand forces.

2. INTRODUCTION TO STRUCTURAL
ENGINEERING
Structural engineering is the science and art of
designing and making, with economy and
elegance, buildings, bridges, frameworks, and
other structures so that they can safely resist
the forces to which they may be subjected

3. TYPES OF STRUCTURES
• Arched Structure
•Beam/Girder Structure
•Cable Suspended Structure
•Planar Truss Structure

5. ARCHED STRUCTURE
•The structure of Arches use a
curved structure which
provides a high resistance to
bending forces. These
structures can only be used
where the surface is solid.

6. BEAM & GIRDER STRUCTURE
•A simple beam is a flat structure
that is supported on both ends .
There are different types of beams,
including : ibeams, ubeams, teams'
and girders, or box beams

7. SUSPENDED STRUCTURE
• Suspension structures, which exist under
conditions of extension, make possible
the full use of the mechanical properties
of high-strength material their light weight
makes it possible to cover structures
that have extremely large spans.

8. PLANAR TRUSS
•Planar Truss is simple
skeletal structure. These
type of structures subjects
only to Tension and
compression forces

9. TYPES OF FORCES ACTING ON AN
STRUCTURE
•Internal Forces
1. Compression
2. Tension
3. Torsion
4. Shear

10. INTERNAL FORCES
• N When the object is pressed or compressed, it
experiences a compression force. This forces
crush a material by squeezing it together.
• N This force is obtained from an external
source. Tension forces stretch a material by
pulling its ends apart.
• N Shear forces bend or tear a material by
pressing different parts in opposite directions at
the same time.
• N This is occurred when an object is twisted.
This force rotates a object from its ends

11. EXTERNAL FORCE
•Load :-
• load is an external force on a structure.
1. Static Load
2. Dynamic Load

12. • Static Loads:-
• A static (dead) load is a permanent force, acting on a
structure. This includes the weight of the structure itself and
the non-moving parts it supports.

13. DYNAMIC LOADS
• A dynamic ( live) load is a changing, or non-permanent
force acting on a structure. This includes the force of the
wind and the weight of things that are in, or on a structure

15. CONCLUSION:-
• Structural Engineering is a creative profession that
makes a significant contribution to infrastructure,
industry, as well as residential and recreational
developments which also includes the development
of buildings, dams, bridges etc., It also considers
the technical, economic, environmental, aesthetic
and social aspects of Structures.
