Designing Of Pre Stressed Concrete With An Internet Based Software

Artificial Neural Network-based Designs of Prestressed Concrete and Composite Structures

This book introduces artificial neural network (ANN)-based Lagrange optimization techniques for a structural design of prestressed concrete structures based on Eurocode 2, and composite structures based on American Institute of Steel Construction and American Concrete Institute standards. The book provides robust design charts for prestressed concrete structures, which are challenging to achieve using conventional design methods. Using ANN-based design charts, the holistic design of a post-tensioned beam is performed to optimize design targets (objective functions), while calculating 21 forward outputs, in arbitrary sequences, from 21 forward inputs. Applies the powerful tools of ANN to the optimization of prestressed concrete structures and composite structures including columns and beams Multi-objective optimizations (MOO) of prestressed concrete beams are performed using an ANN-based Lagrange algorithm Offers a Pareto frontier using an ANN-based MOO for composite beams and composite columns sustaining multi-biaxial loads Heavily illustrated in color and with diverse practical design examples in line with EC2, ACI, and ASTM codes The book offers optimal solutions for structural designers and researchers, enabling readers to construct design charts to minimize their own design targets under various design requirements based on any design code.

Design of Prestressed Concrete to AS3600-2009

The design of structures in general, and prestressed concrete structures in particular, requires considerably more information than is contained in building codes. A sound understanding of structural behaviour at all stages of loading is essential. This textbook presents a detailed description and explanation of the behaviour of prestressed concrete members and structures, both at service loads and at ultimate loads, and in doing so, provides a comprehensive and up-to-date guide to structural design. Much of the text is based on first principles and relies only on the principles of mechanics and the properties of concrete and steel, with numerous worked examples. However, where the design requirements are code specific, this book refers to the provisions of the Australian Standard for Concrete Structures (AS3600-2009) and, where possible, the notation is the same as in AS3600-2009. A parallel volume is written to Eurocode 2, the European Standard for the Design of Concrete Structures. The text runs from an introduction to the fundamentals to in-depth treatments of more advanced topics in modern prestressed concrete structures. It suits senior undergraduate and graduate students, and also practising engineers who want a comprehensive guide to the design of prestressed concrete structures. It retains the clear and concise explanations and the easy-to-read style of the first edition, but the content has been extensively reorganised and considerably expanded and updated. New chapters cover design procedures, actions, and loads; prestressing systems and construction requirements; and connections and detailing. The topic of serviceability is developed extensively throughout. The authors have been researching and teaching the behaviour and design of prestressed concrete structures for more than 35 years, and this updated edition of the book reflects this wealth of experience. The work has also gained much from Ian Gilbert’s active and long-time involvement in the development of the Australian Standards for Concrete Structures (AS3600-2009) and Concrete Bridges (AS5100.5-2012).
