Author: Lothar Mueller, Abdulla Saparov and Gunnar Lischeid | Size: 20 MB | Format:PDF | Quality:Unspecified | Publisher: Springer | Year: 2013 | pages: 480 | ISBN: 3319010166
The book aims to initiate a sustainable use of land and water resources in Central Asia by the transfer of scientific methods. It deals with the most advanced methods worldwide for better monitoring and management of water and land resources.
We offer an array of methods of measuring, assessing, forecasting, utilizing and controling processes in agricultural landscapes. These are laboratory and field measurement methods, methods of resource evaluation, functional mapping and risk assessment, and remote sensing methods for monitoring and modeling large areas. The book contains methods and results of data analysis and ecosystem modeling, of bioremediation of soil and water, field monitoring of soils, and methods and technologies for optimizing land use systems as well. The chapter authors are inventors and advocators of novel transferrable methods. The book starts with an analysis of the current state of water and land resources. Finally concrete proposals for the applicability of novel methods are given.

This book presents a method which simplifies and unifies the design of reinforced concrete (RC) structures and is applicable to any structural element under both normal and seismic loading conditions.
The proposed method has a sound theoretical basis and is expressed in a unified form applicable to all structural members, as well as their connections. It is applied in practice through the use of simple failure criteria derived from first principles without the need for calibration through the use of experimental data. The method is capable of predicting not only load-carrying capacity but also the locations and modes of failure, as well as safeguarding the structural performance code requirements.
In this book, the concepts underlying the method are first presented for the case of simply supported RC beams. The application of the method is progressively extended so as to cover all common structural elements. For each structural element considered, evidence of the validity of the proposed method is presented together with design examples and comparisons with current code specifications. The method has been found to produce design solutions which satisfy the seismic performance requirements of current codes in all cases investigated to date, including structural members such as beams, columns, and walls, beam-to-beam or column-to-column connections, and beam-to-column joints.

The fifth edition of the Highway Capacity Manual (HCM2010), which updates HCM2000, will significantly update how engineers and planners assess the traffic and environmental effects of highway projects: It is the first HCM to provide an integrated multimodal approach to the analysis and evaluation of urban streets from the points of view of automobile drivers, transit passengers, bicyclists, and pedestrians; It is the first to address the proper application of micro-simulation analysis and the evaluation of those results; It is the first to discuss active traffic management in relation to both demand and capacity; and It is the first to provide specific tools and generalized service volume tables, to assist planners in quickly sizing future facilities.

Description:
This comprehensive and well-organized text provides a masterly exposition of the fundamentals of analysis and design of reinforced concrete shells and folded plates, commonly known as thin concrete roof structures. Divided into 20 chapters, the book presents practical designs of different types of domes, cylindrical shells, paraboloids, conoids, and groined shells, as well as various types of folded plates. The text also incorporates tables from ASCE Manual No. 31.
The book explains the subject in such a way that it can be easily understood even by students who have a basic knowledge of mathematics. Students will find the chapters on Folded Plates particularly useful as these structures are easy to build. After studying the book, their analysis and design can be done with greater ease.
Key Features :
Explains step-by-step the procedure for the design of various types of shells and folded plates.
The book is lecture-based, each chapter dealing with one topic. (This enables the teachers to plan their lectures in a proper fashion.)
Provides a large number of worked-out examples and review questions at ends of chapters, which are illustrative and act as brain teasers.
Gives large number of diagrams to illustrate the concepts discussed.
This reader friendly book is intended as a text for the postgraduate students of Civil Engineering/Architecture. As with all the books of Prof. P.C. Varghese, who brings in all his years of experience and expertise into his work, this book too would be of enormous help to practising engineers and architects besides the students.

DRIFT CAPACITY OF REINFORCED CONCRETE COLUMNS SUBJECTED TO DISPLACEMENT REVERSALS
Author: Santiago Pujol | Size: 0.4 MB | Format:PDF | Quality:Unspecified | Year: August 2002 | pages: 77
In previous tests of columns under displacement reversals in the inelastic range of response, different arbitrary displacement histories have been used. Comparisons of drift-capacity data from columns tested under different displacement histories can only be made if displacement-history effects are ignored. Possibly because of this reason, currently available methods for column drift capacity ignore displacement-history effects. To investigate whether drift capacity is a function of displacement history, sixteen cantilever columns were tested under various displacement patterns. The test results indicate that column drift capacity is sensitive to displacement history. For columns cycled beyond yield, drift capacity decreases as a function of the amplitude and number of cycles the column has experienced. Based on measurements of average unit strains in the transverse reinforcement, a model is proposed for estimating the drift capacity for a given column under any symmetric displacement pattern.
