Practical Optimization: Algorithms and Engineering Applications provides a hands on treatment of the subject of optimization. A comprehensive set of problems and exercises makes the book suitable for use in one or two semesters of a first-year graduate course or an advanced undergraduate course. Each half of the book contains a full semester’s worth of complementary yet stand-alone material. The practical orientation of the topics chosen and a wealth of useful examples also make the book suitable as a reference work for practitioners in the field.

Advancements in the efficiency of digital computers and the evolution of reliable software for numerical computation during the past three decades have led to a rapid growth in the theory, methods, and algorithms of numerical optimization. This body of knowledge has motivated widespread applications of optimization methods in many disciplines, e.g., engineering, business, and science, and has subsequently led to problem solutions that were considered intractable not too long ago.

Key Features: Extensively class-tested * Provides a complete teaching package with MATLAB exercises and online solutions to end-of-chapter problems * Includes recent methods of emerging interest such as semidefinite programming and second-order cone programming * Presents a unified treatment of unconstrained and constrained optimization * Uses a practical treatment of optimization accessible to broad audience, from college students to scientists and industry professionals Provides a thorough appendix with background theory so non-experts can understand how applications are solved from point of view of optimization.

This text is developed from the established and well-known textbook Reinforced Concrete Design. It adopts the same format of presentation to cover the design and detailing of reinforced and prestressed concrete members and structures to the new Eurocode for the design of concrete structures (Eurocode 2: Design of Concrete Structures, Part 1).

The ESIS-Technical Committee 9 on Concrete was established in 1990 and has met seven times. A proposal was put to European and extra-European laboratories entitled "Scale effects and transitional failure phenomena of reinforced concrete beams in flexure" which lead to several positive responses. The central topic discussed by the committee was that of the minimum reinforcement in concrete members. The minimum amount of reinforcement is defined as that for which "peak load at first concrete cracking" and "ultimate load after steel yielding" are equal. In this way, any brittle behaviour is avoided as well as any localized failure, if the member is not over-reinforced. In other words, there is a reinforcement percentage range, depending on the size-scale, within which the plastic limit analysis may be applied with its static and kinematic theorems. Carpinteri, Ferro, Bosco and El-Katieb propose a LEFM model, according to which reinforcement reactions are applied directly on the crack surfaces and a compatibility condition is locally imposed on the crack opening displacement in correspondence with the reinforcement. The theoretical model is found to provide a satisfactory estimate of the minimum percentage of reinforcement that depends on the scale and enables the element in flexure to prevent brittle failure.
