Innovative Bridge Design Handbook – Conctruction Rehabilitation and Maintenance Free PDF

Integrating new materials, innovative construction practices, and research from a wide
variety of other innovative engineering and scientific fields (such as aerospace engineering,
materials engineering, and so on), bridge engineering represents the highest
intellectual pursuit of the construction and structural engineering fields. Moreover, as
the demand for new and retrofitted infrastructure is increasing worldwide, the interest
in the bridge engineering field—from both the economic and political points of
view—is also increasing to a remarkable extent.

This book is the culmination of 10years of challenging work, which began when I
discovered that a comprehensive work on the state of the art of bridges—including
theory, design, construction, research and development (R&D), and innovation—
was not present in the existing literature. I hadn’t found any existing manuals with
useful content on the market, as these usually include a lot of content without precise
answers to the most pressing questions relating to the everyday experience in the theory
and practice of bridge engineering and design. I realized I wanted to create an
innovative reference book that could be updated as innovations were made in the field.
This culminated in the first edition of this book.

I initially tried to make a monograph on the matter on my own, spending some
years to research books and articles during my doctoral and postdoctoral studies on
bridge engineering. I then realized that many of my colleagues, including prominent
academicians and engineers from around the world, had the same idea and sought to
write an innovative monograph on bridge engineering and design—not a manual, but a
reference book in which students, academics, and engineers could find useful information
on bridge engineering topics from not merely an academic perspective but also
including research and work in the industry. The preparation of this book has been
very intensive, with thousands of communications passing between the other authors
and myself.

After 5 years, we realized that so much progress in bridge and structural engineering
had been made that a second edition was needed.
I hope that this final work has successfully expressed our thoughts and goals. All
the chapters in this book have been “built” (this term captures the fatigue and the challenges
the contributors overcame while preparing every chapter) and presented by
leading experts in the specific area discussed—engineers and academics who have
very soundly researched their findings. If you are searching for the best design and
research handbook in this area, you can find everything you need to know about bridge
design, engineering, construction, and R&D here in this text.

What is a truss Bridge ? Types of Bridge Trusses

Definition of a truss Bridge:

Truss is a structure of connected elements forming triangular units, and a bridge whose load-bearing superstructure is composed of a truss is a truss bridge.

From a mechanical point of view, truss structures are highly efficient in using the strengths of construction materials due to the fact that only axial forces are resisted in truss members.

Truss bridges are one of the oldest types of modern bridges. Trusses are generally assumed as pinned connection between adjacent truss members. Therefore, the truss members like chords, verticals, and diagonals act only in either tension or compression.

Axial forces in truss bridges under deadweight. (A) Pratt truss. (B) Warren truss.

Moreover, a truss is generally more rigid than a beam because a truss is composed of a variant of triangles and it has the ability to dissipate a load through the whole truss. The truss bridge is also called a beam bridge with braces.

For modern truss bridges, gusset plate connections are generally used, then bending moments and shear forces of members should be considered for evaluating the real performance of the truss bridges, which is achieved by the aid of finite element software.

For the design point of view, however, the pinned connection assumption is considered for security concerns and also for simplifying the structural design and analyses.

In addition, as the axial forces (but not bending moments and shear forces) are generally governs the stress conditions of the members, such assumption generally will not cause large errors between the real bridges and the design models.

According to this assumption, the truss members can be in tension, compression, or sometimes both in response to dynamic loads.

Owing to its simple design method and efficient use of materials, a truss bridge is economical to design and construct.

Short-span truss bridges are built as simply supported, while the large span truss bridges are generally built as continuous truss bridges or cantilever truss bridges.

Truss bridge examples

Types Of Trusses :

There are three common truss configurations that are often used in bridges, namely Warren truss, modified Warren truss, and Pratt truss.

All these truss configurations can be used as an underslung truss, a semithrough truss, or a through truss bridge.

Warren trusses have parallel chords and alternating diagonals. Warren trusses with verticals to reduce panel size are named as modified Warren truss.

Pratt trusses have diagonals sloping downward toward the center and parallel chords.

Truss types according to structural forms. (A) Warren truss. (B) Modified Warren
truss. (C) Pratt truss

Cable Supported Bridges – Concept And Design Free PDF

The decision to prepare a manuscript for a book titled CABLE SUPPORTED BRIDGES was taken by Niels J. Gimsing in 1980 following his three-year affiliation as an adviser on bridge technology to Statsbroen Store Bœlt—the client organization established to design and construct a bridge across Storebælt (Great Belt) in Denmark.

During the design period from 1976 to 1979, a large number of different designs for cable-stayed bridges (with spans up to 850 m) and suspension bridges (with spans up to 1800 m) were thoroughly investigated and it was during that period the idea matured to write a book covering both cable-stayed bridges and suspension bridges.

The chance to prepare the manuscript came in 1979 when the Danish Government decided to postpone the construction of the Storebælt Bridge and to keep the design work at rest for a period of five years.

Accelerated Bridge Construction – Best Practices and Techniques Free PDF

This textbook has been developed for the purpose of incorporating the latest developments in accelerated bridge construction (ABC) projects. Its objectives are to focus on creating awareness, educate, train, and inform bridge engineers in the art and science of effective rapid construction and delivery to the public.

It will entice the State Department of Transportations and its staff to select rapid construction techniques and save travel time of the public and money, especially during construction.

The applications of routine design procedures using AASHTO LRFD Specifications, State Design Manuals with specific reference to ABC, and the vast amount of bridge design software will not change except for new load combinations resulting from Lifting, transporting, erection, roll-in, slide-in, or float-in loads, etc.
