Dongzhou Huang,Bo Hu - Concrete Segmental Bridges
Theory, Design, and Construction to AASHTO LRFD Specifcations
CRC, 2020
pdf, 1028 pages, english
ISBN: 978-1-4987-9900-3
Segmental concrete bridges have become one of the main options for major transportation projects world-wide. They offer expedited construction with minimal traffic disruption, lower life cycle costs, appealing aesthetics and adaptability to a curved roadway alignment. The literature is focused on construction, so this fills the need for a design-oriented book for less experienced bridge engineers and for senior university students.
It presents comprehensive theory, design and key construction methods, with a simple design example based on the AASHTO LRFD Design Specifications for each of the main bridge types. It outlines design techniques and relationships between analytical methods, specifications, theory, design, construction and practice. It combines mathematics and engineering mechanics with the authors’ design and teaching experience. |

Hwai-Chung Wu, Christopher D. Eamon - Strengthening of Concrete Structures Using Fiber Reinforced Polymers
Elsevier, 2017
pdf, 342 pages, english
ISBN: 978-0-08-100636-8
Strengthening of Concrete Structures Using Fiber Reinforced Polymers (FRP): Design, Construction and Practical Applications presents a best practice guide on the structural design and strengthening of bridge structures using advanced Fiber Reinforced Polymer (FRP) composites. The book briefly covers the basic concepts of FRP materials and composite mechanics, while focusing on practical design and construction issues, including inspection and quality control, paying special attention to the differences in various design codes (US, Japan, and Europe) and recommendations.
At present, several design guides from the US, Japan, and Europe are available. These guidelines are often inconsistent and do not cover all necessary design and inspection issues to the same degree of detail. This book provides a critical review and comparison of these guidelines, and then puts forward best practice recommendations, filling a significant gap in the literature, and serving as an important resource for engineers, architects, academics, and students interested in FRP materials and their structural applications. Written from a practitioner's point-of-view, it is a valuable design book for structural engineers all over the world.
- Includes a large quantity of design examples and structural software to facilitate learning and help readers perform routine design.
- Provides recommendations for best practices in design and construction for the strengthening of bridge structures using advanced fiber-reinforced polymer (FRP) composites.
- Presents comprehensive guidelines on design, inspection, and quality control, including laboratory and field testing information.

Singiresu Rao - The Finite Element Method in Engineering, Sixth Edition
Elsevier, 2018
pdf, 754 pages, english
ISBN 978-0-12-811768-2
Extended Finite Element and Meshfree Methods provides an overview of, and investigates, recent developments in extended finite elements with a focus on applications to material failure in statics and dynamics. This class of methods is ideally suited for applications, such as crack propagation, two-phase flow, fluid-structure-interaction, optimization and inverse analysis because they do not require any remeshing. These methods include the original extended finite element method, smoothed extended finite element method (XFEM), phantom node method, extended meshfree methods, numerical manifold method and extended isogeometric analysis.
This book also addresses their implementation and provides small MATLAB codes on each sub-topic. Also discussed are the challenges and efficient algorithms for tracking the crack path which plays an important role for complex engineering applications.
- Explains all the important theory behind XFEM and meshfree methods.
- Provides advice on how to implement XFEM for a range of practical purposes, along with helpful MATLAB codes.
- Draws on the latest research to explore new topics, such as the applications of XFEM to shell formulations, and extended meshfree and extended isogeometric methods.
- Introduces alternative modeling methods to help readers decide what is most appropriate for their work.
