NEW TRENDS IN CIVIL ENGINEERING

TOPIC INTRODUCTION HISTORY OF CIVIL ENGG Disaster faced by ancent structuers DEVELOPMENT CIVIL ENGG. AT PRESENT THE NEW TREANDS IN CIVIL ENGG.

CIVIL ENGINEERINGCivil engg. Deals with construction ,development nd maintainance of the physically nd naturally build enviornmentIt’s the oldest branch of engg.Civil eng. Is related to techonology from ancent time.

ANCENT TECHONOLOGY IN CIVIL ENGG.

I. Historical Survey(A) Palaeontological background

(B) First Shelters - Later Palaeolithic(C) Domestic Building in the Middle East -

Neolithic, Chalcolithic(D) Monumental Building - ca. 3000 BC - 500 AD.

1. Megalithic Construction2. Mesopotamian Construction

3. Egyptian Construction4. Levanto-Aegaean Construction

5. Classical Greek Construction6. Roman Construction

7. Late Antique Construction - Western and Eastern

II. Materials of ConstructionTheir winning/manufacture, processing and utilisation with tools of trace(A) Wood(B) Earth/Clay(C) Stone(D) Lime/Gypsum(E) Bitumen(F) Glass(G) Metal

III. Structural SystemsFramed, Load bearing, Trabeated, Arcuated

V. Forms of Construction(A) Foundations(B) Walls(C) Point Supports(D) Floors(E) Doors(F) Windows(G) Steps(H) Roofs

DISASTER TO ANCENT STRUCTURES

 Big ambitions led to taking big chances, which often resulted in faulty construction and, occasionally, deadly collapse–

failure is part of the learning process

DEVEOPMENT IN CIVIL ENGGEvery disaster nd every mistake leads to

improvement.Civil engg. Use the techonology for the betterment

nd nd to fight with tough situationsA lot of changes comes in civil engg with the

demand of timeThese all things leads to development in

technique ,working ..

Civil Engg At Present

Every one in this world is dependend on civil engg for a better nd comfortable life..

It all happen due to new construction method nd techonology

THE MEGA STRUCTURES

NEW TREANDS IN CIVIL ENGG. Civil engg adopts a lot of new treands..the

biggest example of new treands is the worlds highest tower “The BURJ KHLIFA”

A lots of new technologies were used in “BURJ KHALIFA”

The exterior mirror tech is one of those tech that are used in BURJ KHALIFA

THE BURJ KHALIFA

TYPE OF COATING DONE ON THE GLASS LAYER

THREE LAYERS OF GLASS USED FOR EXTERIOR WORK

ITS JUST A CIVIL ENGG. WHO GIVE HUMAINITY

COMFORTABLE LIFE EVEN AT A HEIGHT OF 800M FROM

THE GROUND LEVEL..

THESE MEGA STRUCTURES NEEDS PROPER LIFE-TIME MAINTAINANCE .

THIS NEW EXTERIOR MIRROR TECH IS HELPFUL IN ESTATIC VIEW AS WELL AS HELPS IN PROTECTION FRONM UV ND IR RAYS
