The use of piled raft foundations has significantly increased over the last few decades since taking into account the contribution of the raft to the overall bearing capacity enabled the engineers to design much more efficient piled foundations which perform as well as the conventionally designed ones with significantly lower number of piles. However, although many researchers have been studying on this subject, a user-friendly design procedure is still not available in the literature. This book, therefore, offers two different simple methods to estimate the settlements of the piled raft foundations. Utilizing the charts provided in this book, the settlement of a piled raft foundation can be obtained by simple hand calculations in the first method while it can be calculated by computerized analysis in the second one. This book should be especially useful for the geotechnical experts and/or engineers looking for a simplified method for the analysis of piled rafts and academicians who are interested in thesubject.

Computational complexity is a serious bottleneck for the design process in virtually any engineering area. While migration from prototyping and experimental-based design validation to verification using computer simulation models is inevitable and has a number of advantages, high computational costs of accurate, high-fidelity simulations can be a major issue that slows down the development of computer-aided design methodologies, particularly those exploiting automated design improvement procedures, e.g., numerical optimization. The continuous increase of available computational resources does not always translate into shortening of the design cycle because of the growing demand for higher accuracy and necessity to simulate larger and more complex systems. Accurate simulation of a single design of a given system may be as long as several hours, days or even weeks, which often makes design automation using conventional methods impractical or even prohibitive. Additional problems include numerical noise often present in the simulation data, possible presence of multiple locally optimum designs, as well as multiple conflicting objectives. In this edited book, various techniques that can alleviate solving computationally expensive engineering design problems are presented. One of the most promising approaches is the use of fast replacement models, so-called surrogates, that reliably represent the expensive, simulation-based model of the system/device of interest but they are much cheaper and analytically tractable. Here, a group of international experts summarize recent developments in the area and demonstrate applications in various disciplines of engineering and science. The main purpose of the work is to provide the basic concepts and formulations of the surrogate-based modeling and optimization paradigm, as well as discuss relevant modeling techniques, optimization algorithms and design procedures. Therefore, this book should be useful to researchers and engineers from any discipline where computationally heavy simulations are used on daily basis in the design process.

Recent earthquakes in many countries of the world have confirmed the potential for very large seismic events that until now were not forecast. The level of disturbance and destruction of highways and bridges as well as life, suffered during these dominant earthquakes were far greater than structural engineers and their associated design codes had predicted. One important lesson that has been learnt is that it is vital that bridges, which connect major transportation routes, must continue to function after an earthquake. . In the quest of this realization, new technologies and design efforts by engineers have resulted in the development of seismic protection systems, which include Shock Transmission Unit (STU) together with various seismic isolation and energy mitigation devices. In the only book to provide independent, non-proprietary information on the design and application of STUs, the author offers information on a wide range of different applications, including new and existing highway and railway bridges, as well as non-bridge structures such as nuclear power plants. Illustrated case studies included throughout, Shock Transmission Units in Bridge Engineering is written by a proven expert in STUs and the only world authority on the subject.

A detailed guide to Eurocode 6 Design of Masonry Structures: Part 1-1 Common rules for reinforced and unreinforced masonry structures, dealing with the various sections in EN1996-1-1: 1 General Introduction and Terminology - 2 Basis of design - 3 Materials - 4 Durability - 5 Structural analysis - 6 Ultimate Limit State - 7 Serviceability Limit State - 8 Detailing - 9 Execution.

A valuable insight is given into the code that addresses unreinforced masonry and reinforced masonry where the reinforcement is added to provide ductility, strength or improve serviceability and provides the structural rules for designing a composite material comprising masonry units and mortar.

This book complements the Eurocode standard by explaining the areas where change has overtaken the traditional approach used in the previous British Standard. Includes UK National Annex for EN 1996-1-1.

This series of "Designers' Guides to the Eurocodes" provides comprehensive guidance in the form of design aids, indications for the most convenient design procedures and worked examples. The books also include background information to aid the designer in understanding the reasoning behind and the objectives of the codes. All of the individual guides work in conjunction with the "Designers' Guide to EN 1990 Eurocode: Basis of Structural Design". The part of Eurocode 5 covered by this guide, EN 1995-1, addresses the common rules and rules for buildings, including structural fire design. This Designers' Guide looks specifically at timber buildings, including full explanation and commentary on the code with examples, and direction to the National Annex documents.
