China is the most rapidly urbanizing nation in the world, with an urban population that may well reach one billion within a generation. Over the past 25 years, surging economic growth has propelled a construction boom unlike anything the world has ever seen, radically transforming both city and countryside in its wake. The speed and scale of China's urban revolution challenges nearly all our expectations about architecture, urbanism and city planning. China's ambition to be a major player on the global stage is written on the skylines of every major city. This is a nation on the rise, and it is building for the record books.
China is now home to some of the world's tallest skyscrapers and biggest shopping malls; the longest bridges and largest airport; the most expansive theme parks and gated communities and even the world's largest skateboard park. And by 2020 China's national network of expressways will exceed in length even the American interstate highway system. China's construction industry, employing a workforce equal to the population of California, has been erecting billions of square feet of housing and office space every year. But such extensive development has also meant demolition on a scale unprecedented in the peacetime history of the world. Nearly all of Beijing's centuries-old cityscape has been bulldozed in recent years, and redevelopment in Shanghai has displaced more families than 30 years of urban renewal in the United States. China's cities are also rapidly sprawling across the landscape, churning precious farmland into a landscape of superblock housing estates and single-family subdivisions laced with highways and big-box malls. In a mere generation, China's cities have undergone a metamorphosis that took 150 years to complete in the United States.
The Concrete Dragon: China's Urban Revolution and What it Means for the World sheds light on this extraordinary chapter in world urban history. The book surveys the driving forces behind the great Chinese building boom, traces the historical precedents and global flows of ideas and information that are fusing to create a bold new Chinese cityscape, and considers the social and environmental impacts of China's urban future.
The Concrete Dragon provides a critical overview of contemporary Chinese urbanization in light of both China's past as well as earlier episodes of rapid urban development elsewhere in the world-especially that of the United States, a nation that itself once set global records for the speed and scale of its urban ambitions.

This highly original and sophisticated look at architecture helps us to understand the cultural significance of the buildings that surround us. It avoids the traditional style-spotting approach and instead gives us an idea of what it is about buildings that moves us, and what it is that makes them important artistically and culturally. The book begins by looking at how architecture acquires meaning through tradition, and concludes with the exoticism of the recent avant-garde period. Illustrations of particular buildings help to anchor the general points with specific examples, from ancient Egypt to the present day.

Gravity load designed (GLD) reinforced concrete (RC) buildings represent a common type of construction in the Mid-America Region. These buildings have limited lateral resistance and are susceptible to story mechanisms during earthquake loading. Fragility estimates are developed to assess the seismic vulnerability of GLD RC buildings in the Mid-America Region. Fragility is defined as the conditional probability of reaching or exceeding a performance level for a given earthquake intensity measure. Five sample buildings of various story heights (1, 2, 3, 6, and 10 stories) are used to represent generic RC frame buildings of 1 to 10 stories tall. A Bayesian methodology is used to develop probabilistic demand models to predict the maximum inter story drift given the spectral acceleration at the fundamental period of the building. The unknown parameters of the demand models are estimated using the simulated response data obtained from nonlinear time history analyses of the structural models for a suite of synthetic ground motions, developed for Memphis, Tennessee. Seismic structural capacity values are selected corresponding to the performance levels or damage states as specified in FEMA-356 and as computed by nonlinear pushover analyses.
For the sample buildings, fragility estimates are developed using the predicted drift demands and structural capacity values. Confidence bounds are developed to represent the epistemic uncertainty inherent in the fragility estimates. In addition, bivariate fragility estimates, formulated as a function of spectral acceleration and the fundamental building period, are developed from the fragility estimates of the individual buildings. The bivariate fragilities can be used to quantify the seismic vulnerability of GLD RC frame buildings of 1 to 10 stories. Using the Bayesian approach, a framework is developed to update the analytical fragility estimates using observed damage data or experimental test data. As an illustration of the updating framework, the analytical bivariate fragility estimates for the sample buildings in the Mid-America Region are updated using the damage data obtained from 1994 Northridge, California earthquake.
Furthermore, to investigate and demonstrate the increase in seismic performance of the GLD RC frame buildings, the columns of the 2 and 3 story buildings are retrofitted by column strengthening. Fragility estimates developed for the retrofitted buildings show the effectiveness of the retrofit technique by the improved seismic performance of GLD RC frame buildings.

ABSTRACT
Puerto Rico is situated in an earthquake prone region. Most of residential buildings in Puerto Rico are reinforced concrete structures. Because of the imminent risk of being affected by a strong earthquake, it is important to study their damage vulnerability. The lack of local earthquake vulnerability curves for Puerto Rico and the fact that local construction practice differs from that in USA motivates the author to look at the development of reliable fragility curves based on typical buildings properties and selection of ground motions based on local geology characteristics and past worldwide earthquakes scaled to different peak ground acceleration to obtain a wide range of maximum accelerations. This study is directed to low rise and medium rise concrete residential buildings in Puerto Rico. Typical lateral resisting systems, comprising moment frames and structural walls are considered. The analytical models are two-dimensional
and are analyzed using the nonlinear dynamic time history method considering flexural nonlinear behavior for frames and both flexural and shear nonlinear behavior for shear walls.
Algan’s formulation (1982) and HAZUS drift limits were used to calculate the expected damage of the models. Damage to structures is quantified based on the inter-story drift ratio of the
structure. The damage states considered were: Minor, Moderate, Substantial and Major, for Algan and Slight, Moderate, Extensive and Complete for HAZUS. With this information, lognormal functions expressed in the form of two parameters (log-median and log-standard deviation) were fitted and fragility curves developed as a function of PGA. It is common for concrete housing to have resisting elements oriented in only one direction. These structures are evaluated for forces in both directions independently and also taking in account both directions simultaneously. Multistory residential buildings in Puerto Rico commonly have shear walls oriented in both directions. A set of four fragility curves, one for each damage state is developed
for each scenario studied. A total of 13 sets of fragility curves for each method are proposed. Multistory models proved to be the least vulnerable of the structures analyzed. These curves are
useful tools for the insurance companies in Puerto Rico in order to improve their risk assessments.

This book is intended for a beginner with Elementary Knowledge of Structural mechanics and Fortran Programming. Stiffness and flexibility methods are commonly known as Matrix methods. Of these, the stiffness method using member approach is amenable to Computer Programming and is widely used for structural analysis.
The emphasis in the book is on explaining basic fundamentals of this approach and on developing programs. This is achieved through extremely simple Style of presentation in lucid Language and proceeding in stages from simple to Complex structures. Unified theory with a single complex Program is totally avoided. Instead, each skeletal structure is discussed in a separate chapter with simple, short and transparent program. Theory is presented in matrix notations along with clear mention of scalar Components for proper understanding of the Physical quantities. Illustrative solved examples explain data preparation, data file and interpretation of the results. Alternate possibilities of data preparation are mentioned and used. The information about data generation, skyline storage, variable dimensioning and frontal technique is intentionally presented separately at a later Stage to Help reader in modifying initial simple programs.
The treatment of flexibility and direct stiffness method is limited to introduction of elementary concepts. Transfer matrix method, plastic analysis by stiffness method and sub-structure method are included as additional Topics of interest. A chapter is devoted to present an alternate view of stiffness method as a variational approach. Non-linear structural behaviour and techniques commonly adopted to evaluate non-linear response are discussed. Formulae for displacements in beams and restraining actions are included in Appendices A and B. Appendix C discusses various methods of solution of simultaneous Algebraic equations. Exercises are included at the end of each chapter.
The book will be useful to undergraduate and postgraduate Civil Engineering students and also to those preparing for competitive examinations.

The purpose of this book is has to bridge the gap between the traditional Geomechanics and Numerical Geotechnical Modelling with applications in science and practice. Geomechanics is rarely taught within the rigorous context of Continuum Mechanics and Thermodynamics, while when it comes to Numerical Modelling, commercially available finite elements or finite differences software utilize constitutive relationships within the rigorous framework. As a result, young scientists and engineers have to learn the challenging subject of constitutive modelling from a program manual and often end up with using unrealistic models which violate the Laws of Thermodynamics. The book is introductory, by no means does it claim any completeness and state of the art in such a dynamically developing field as numerical and constitutive modelling of soils. The author gives basic understanding of conventional continuum mechanics approaches to constitutive modelling, which can serve as a foundation for exploring more advanced theories. A considerable effort has been invested here into the clarity and brevity of the presentation. A special feature of this book is in exploring thermomechanical consistency of all presented constitutive models in a simple and systematic manner.
