Konrad Bergmeister Concrete Structures for Wind Turbines


The wind energy industry in Germany has an excellent global standing when it comes to the development and construction of wind turbines. Germany currently represents the worlds largest market for wind energy. The ongoing development of ever more powerful wind turbines plus additional requirements for the design and construction of their offshore foundation structures exceeds the actual experiences gained so far in the various disciplines concerned. This book gives a comprehensive overview for planning and structural design analysis of reinforced concrete and pre-stressed concrete wind turbine towers for both, onshore and offshore wind turbines. Wind turbines represent structures subjected to highly dynamic loading patterns. Therefore, for the design of loadbearing structures, fatigue effects – and not just maximum loads – are extremely important, in particular in the connections and joints of concrete and hybrid structures. There multi-axial stress conditions occure which so far are not covered by the design codes. The specific actions, the nonlinear behaviour and modeling for the structural analysis are explained. Design and verification with a focus on fatigue are adressed. The chapter Manufacturing includes hybrid structures, segmental construction of pre-stressed concrete towers and offshore wind turbine foundations. Selected chapters from the German concrete yearbook are now being published in the new English «Beton-Kalender Series» for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn «Beton-Kalender» has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in «ferro-concrete» structures until – as the books first editor, Fritz von Emperger (1862-1942), expressed it – the «tempestuous development» in this form of construction came to an end. However, the «Beton-Kalender» quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since.

While the static behavior of concrete has been the subject of numerous works, the same cannot be said for the dynamic behavior. This book sets out to remedy this situation: it begins by presenting the most frequently used experimental techniques in the study of the dynamic behavior of concrete, then continues by examining seismicity and seismic behavior, soil behavior, models of concrete structures subject to seismic activity, seismic calculation methods of structures, and paraseismic engineering.

Ulrich Häußler-Combe Computational Methods for Reinforced Concrete Structures


The book covers the application of numerical methods to reinforced concrete structures. To analyze reinforced concrete structures linear elastic theories are inadequate because of cracking, bond and the nonlinear and time dependent behavior of both concrete and reinforcement. These effects have to be considered for a realistic assessment of the behavior of reinforced concrete structures with respect to ultimate limit states and serviceability limit states. The book gives a compact review of finite element and other numerical methods. The key to these methods is through a proper description of material behavior. Thus, the book summarizes the essential material properties of concrete and reinforcement and their interaction through bond. These basics are applied to different structural types such as bars, beams, strut and tie models, plates, slabs and shells. This includes prestressing of structures, cracking, nonlinear stressstrain relations, creeping, shrinkage and temperature changes. Appropriate methods are developed for each structural type. Large displacement and dynamic problems are treated as well as short-term quasi-static problems and long-term transient problems like creep and shrinkage. Most problems are illustrated by examples which are solved by the program package ConFem, based on the freely available Python programming language. The ConFem source code together with the problem data is available under open source rules at concrete-fem.com. The author aims to demonstrate the potential and the limitations of numerical methods for simulation of reinforced concrete structures, addressing students, teachers, researchers and designing and checking engineers.

Günter Rombach Spannbetonbau


Prestressing increases the load-bearing capacity of reinforced concrete structures significantly and also improves their serviceability. Long span bridges, very slender stressed ribbon or large shell structures as well as tall liquid containers would not be possible without prestressing or at the very least very uneconomical. Aside from the traditional fields of application in bridge and precast construction, prestressing is increasingly being used in buildings and industrial structures. Thus, any structural engineer should possess sufficient know-how in prestressed concrete construction to which this book aims to contribute. This book comprehensively elucidates the design and construction of prestressed concrete structures and illustrates the various prestressing methods and systems. All the necessary background knowledge is provided for the design and construction of safe and durable prestressed concrete structures. The numerous innovations of the last few years in analysing and detailing prestressed concrete structures as well as in the prestressing systems themselves required an update from the first edition of this book. This edition also incorporates the recent changes in the codes DIN 1045-1 and DIN-Fachbericht 102 as well as suggestions from practical experience.

Md. Mamunur Roshid Fabrication of a Wind turbine with different pitch angle the blade


Windmills served ones to grind grain, pump water and for other jobs but today windmills are mostly used to generate electricity when harnessed to electric generators and commonly referred to as wind turbines. Wind is simply Air in motion. The Earth's winds contain vast amounts of energy. Today, advanced wind turbines offer an efficient means of capturing wind energy and using it to produce electricity. A windmill is a machine that converts the kinetic energy of the wind into mechanical rotary energy by using rotating blades. Wind turbines have two or three long, light-weight blades that turn quickly. The longer the blade and the greater the wind speed, the more electricity generated. The purpose of this project is to design and fabricate a wind turbine to increase mechanical efficiency of wind turbine by changing the length, shape and different pitch angle of turbine blade.
