Planning and Design of Airports Fifth Edition PDF

Planning and Design of Airports Fifth Edition PDF

 

In the 16 years since this last update, it may be said that the changes to the practice of airport planning and design have been more significant than in any other era in the history of aviation.


Implementation of twenty-first-century technologies has resulted in the first major overhaul to aircraft and air navigation systems in generations, computer-based analytical and design models have replaced antiquated monographs and estimation tables, and highly significant geopolitical events have all but rewritten the rules of
planning, designing, and operating civil-use airports.

 

These significant enhancements to the aviation system have resulted in unique challenges in creating an updated fifth edition of this important and highly accepted text. While every attempt was made to keep to the traditional structure of the book and to preserve the theoretical strengths for which it is most well known, much of the material in the previous edition required more replacement than simply being made current.

Within this latest edition the reader will find, for example, new and entirely different strategies to estimate required runway lengths and their associated required pavement thicknesses. This text attempts to maintain the flavor of previous editions while understanding, for example, that airport navigational aids of the previous century are becoming all but obsolete, in favor of a digital, satellite-based communication and navigational system, and that airport financing strategies are in a revolutionary state, given anticipated changes to federal aviation funding mechanisms.


Updating this edition has, in fact, been a continuous “race against time,” as important changes to the aviation system were constantly occurring during the process.

Fundamentals Of Bridge Design Free PDF Notes

Fundamentals Of Bridge Design Free PDF Notes

 

A bridge is a structure providing passage over an obstacle. The obstacle may be a river, valley, road or railway. The  passage may be for highway or railway traffic, pedestrian, canal or pipeline.


As the saying “Build bridges and you will have a friend” goes, bridges have a unique attribute of connecting different people. Rivers and mountains form physical barriers between people to interact, trade with one another, live and work together. For Ethiopia this holds especially true as the country is known as “The Water Tower of Africa” due to the high
rainfall we receive, which resulted in quite many big rivers dissecting the rough terrain and flowing deep in the valleys. Consequently we are composed of people speaking about 82 different languages.


Transportation network is crucial for the development and prosperity of a country. Investment by both nationals and foreigners is crucial for economic development of a country, and one of the criteria that foreign investors weigh in their investment decisions in a country is the level of development of the transportation network. Bridges provide essential
links in highways and railways at obstacles. The cost of bridges (and culverts) is a significant proportion of a highway project.


Many cities and towns are established near rivers and bridges add to the beauty of cities and towns. Bridges aid the social, cultural and economic improvements of the locations around them.


Bridges also have military strategic importance. The mobility of an army at war is often affected by the availability or otherwise of bridges to cross rivers. Military training puts special emphasis on learning how to build new bridges quickly while advancing and destroy bridges while retreating.


Bridge engineering is one of the fascinating fields in civil engineering calling for expertise in many areas: structural analysis and design, geotechniques, traffic projection, surveying, runoff calculation and methods of construction. A bridge engineer has to have an appreciation of economics and aesthetics besides ability in analysis and design.

Traffic And Pavement Engineering Free PDF

Traffic And Pavement Engineering Free PDF

 

This book implements a unique kind of approach and categorizes transportation engineering topics into fve major key areas, as shown below:
    • Volume I: Traffic and Pavement Engineering
      • Part I ”Traffic Engineering” deals with the functional part of transportation systems and introduces engineering techniques, practices, and models that are applied to design traffc systems, control traffc fow and movement, and construct proper roads and highways to achieve safe and effcient movement of people and traffc on roadways.
      • Part II ”Pavement Materials, Analysis, and Design” deals with both the structural and functional parts of transportation facilities and introduces engineering techniques and principles of the uses of high-quality and sustainable materials that are employed to design, maintain, and construct asphalt-surfaced road pavements and concrete rigid pavements. The ultimate goal of pavement engineering is to provide a pavement structure that is safe, durable, sustainable, and capable of carrying the predicted traffc loads under prevailing climatic conditions. Proper structural design of pavements is one that takes into consideration the mechanistic analysis of pavements for stresses and strains that can predict the performance of the pavement with time. This section fulflls this goal by presenting the subject in a unique manner.
  • Volume II: Highway Planning, Survey, and Design
    • Part I ”Urban Transportation Planning” presents a process that involves a multi-modal approach and comprehensive planning steps and models to design and evaluate a variety of alternatives for transportation systems and facilities, predict travel demand and future needs, and manage the facilities and services for the different modes of transportation to fnally achieve a safe, effcient, and sustainable system for the movement of people and goods.
    • Part II ”Highway Survey” presents the basic concepts and standard procedures necessary to make precise and accurate distance, angle, and level measurements for highway alignment, cross-sections, and earth quantities used in the design of highways.
    • Part III ”Geometric Design of Highways” deals with engineering design techniques, standards, and models that control the three main elements of highway geometric design: horizontal and vertical alignments, profle, and cross-section to achieve the primary objectives of geometric design: safety, effciency, and sustainability.

OffShore Geotechnical Engineering Free PDF

OffShore Geotechnical Engineering Free PDF

 

Offshore Geotechnical Engineering Design practice in offshore geotechnical engineering has grown out of onshore practice, but the two application areas have tended to diverge over the last 30 years, driven partly by the scale of the foundation and anchoring elements used offshore and partly by fundamental differences in construction and installation techniques.

As a consequence, offshore geotechnical engineering has grown as a speciality.

The book’s structure follows a familiar pattern that mimics the flow of a typical off-shore project.

In the early chapters, it provides a brief overview of the marine environment, offshore site investigation techniques and interpretation of soil behaviour. It proceeds to cover geotechnical design of piled foundations, shallow foundations and anchoring systems.

Three topics are then covered that require a more multi-disciplinary approach: the design of mobile drilling rigs, pipelines and geohazards.

Offshore Geotechnical Engineering serves as a framework for undergraduate and postgraduate courses, and will appeal to professional engineers specialising in the offshore industry. It is assumed that the reader will have some prior knowledge of the basics of soil mechanics and foundation design.

The book includes sufficient basic material to allow readers to build on this previous knowledge, but focuses on recent developments in analysis and design techniques in offshore geotechnical engineering.
