In risk studies, engineers often have to consider the consequences of an accident leading to a shock on a construction. This can concern the impact of a ground vehicle or aircraft, or the effects of an explosion on an industrial site.
This book presents a didactic approach starting with the theoretical elements of the mechanics of materials and structures, in order to develop their applications in the cases of shocks and impacts. The latter are studied on a local scale at first. They lead to stresses and strains in the form of waves propagating through the material, this movement then extending to the whole of the structure.
The first part of the book is devoted to the study of solid dynamics where nonlinear behaviors come into play. The second part covers structural dynamics and the evaluation of the transient response introduced at the global scale of a construction. Practical methods, simplified methods and methods that are in current use by engineers are also proposed throughout the book.
The aim of this book is to present theoretical elements regarding solids and structures, as well as modeling tools in order to study the vulnerability of a structure to a short duration action, generally of accidental nature. The book takes the point of view of an engineer seeking for the modeling of the physics at stake to relevantly carry out his study. The book originality is that it gathers elements from various fields of engineering sciences, for the purpose of a practical objective.

Could anyone please give me a MATLAB or R code for the selection of significant input variables for neural network modelling. It would be highly appreciated. I have total 69 input and 1 output. So, I need to select the most significant input variables from 69 inputs to develop a neural network model. Since I will develop model in neural network platform, so MATLAB (or R) code in the same platform would be a great support to my work.
Shanghai Tower will anchor the city’s Lujiazui district, which has emerged as one of East Asia’s leading financial centers. Designed by a local team of Gensler architects to embody Shanghai’s rich culture, the 632-meter-high mixed-use building will complete the city’s super-highrise precinct. It is the most forward-looking of the three towers symbolizing Shanghai’s past, present, and future. The new tower takes inspiration from Shanghai’s tradition of parks and neighborhoods. Its curved façade and spiraling form symbolize the dynamic emergence of modern China. By incorporating sustainable best practices, Shanghai Tower is at the forefront of a new generation of super-highrise towers, achieving the highest level of performance and offering unprecedented community access.

The Urban Climatic Map: A Methodology for Sustainable Urban Planning
Author(s)/Editor(s): Edward Ng and Chao | Size: 84.8 MB | Format:PDF | Quality:Original preprint | Publisher: Routledge | Year: 2014 | pages: 528 | ISBN: 1849713766
Rapid urbanization, higher density and more compact cities have brought about a new science of urban climatology. An understanding of the mapping of this phenomenon is crucial for urban planners. The book brings together experts in the field of Urban Climatic Mapping to provide the state of the art understanding on how urban climatic knowledge can be made available and utilized by urban planners. The book contains the technology, methodology, and various focuses and approaches of urban climatic map making. It illustrates this understanding with examples and case studies from around the world, and it explains how urban climatic information can be analysed, interpreted and applied in urban planning. The book attempts to bridge the gap between the science of urban climatology and the practice of urban planning. It provides a useful one-stop reference for postgraduates, academics and urban climatologists wishing to better understand the needs for urban climatic knowledge in city planning; and urban planners and policy makers interested in applying the knowledge to design future sustainable cities and quality urban spaces.

The bright future and exciting possibilities of BIM
Many architects and engineers regard BIM as a disruptive force, changing the way building professionals design, build, and ultimately manage a built structure. With its emphasis on continuing advances in BIM research, teaching, and practice, Building Information Modeling: BIM in Current and Future Practice encourages readers to transform disruption to opportunity and challenges them to reconsider their preconceptions about BIM.
Thought leaders from universities and professional practice composed essays exploring BIM's potential to improve the products and processes of architectural design including the structure and content of the tools themselves. These authors provide insights for assessing the current practice and research directions of BIM and speculate about its future. The twenty-six chapters are thematically grouped in six sections that present complementary and sometimes incompatible positions:
Design Thinking and BIM
BIM Analytics
Comprehensive BIM
Reasoning with BIM
Professional BIM
BIM Speculations
Together, these authors provide stimulating ideas regarding new directions in building information modeling.

Building information modelling (BIM) is revolutionising building design and construction. For architects, BIM has the potential to optimise their creativity while reducing risk in the design and construction process, thus giving them a more significant role in the building process. This book demonstrates how innovative firms are using BIM technologies to move design away from the utilitarian problems of construction, engaging them in a stunning new future in the built environment.
Whereas recent books about BIM have tended to favour case–study analyses or instruction on the use of specific software, BIM Design highlights how day–to–day design operations are shaped by the increasingly generative and collaborative aspects of these new tools. BIM strategies are described as operations that can enhance design rather than simply make it more efficient. Thus this book focuses on the specific creative uses of information modelling at the operational level, including the creative development of parametric geometries and generative design, the evaluation of environmental performance and the simulation and scheduling of construction/fabrication operations.
This book also engages BIM s pragmatic efficiencies such as the conflict checking of building systems and the creation of bills of quantities for costing; and in so doing it demonstrates how BIM can make such activities collaborative.
Throughout, projects are used to illustrate the creative application of BIM at a variety of scales. These buildings showcase work by fi rms executing projects all over the world: SHoP Architects and Construction (New York), Morphosis (Los Angeles), Populous (London), GRO Architects (New York), Reiser + Umemoto (New York), Gensler (Shanghai) and UNStudio (Amsterdam).
