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

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

STRUCTURES

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.

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

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.

PLANAR TRUSS

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

TYPES OF FORCES ACTING ON AN STRUCTURE

•Internal Forces1. Compression2. Tension3. Torsion4. Shear

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

EXTERNAL FORCE

•Load :-• load is an external force on a structure.

1. Static Load2. Dynamic Load

• 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.

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

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.
