D. Chandrasekharam, Jochen Bundschuh, "Low-Enthalpy Geothermal Resources for Power Generation"
Taylor & Francis; 1 edition (January 7, 2008) | English | 0415401682 | 172 pages | PDF | 10.04 MB
In many developing countries the exponentially growing electricity demand can be covered by using locally available, sustainable low-enthalpy geothermal resources (80-150 °C). Such low-enthalpy sources can make electricity generation more independent from oil imports or from the over-dependence on hydropower.
Until now this huge energy resource has only been used by some developed countries like the USA, Iceland and New Zealand.
The reason why low-enthalpy geothermal resources are not used for electricity generation is that there is still a misconception that low-enthalpy thermal fluids are fit only for direct application.
The advancement of drilling technology, development of efficient heat exchangers and deployment of high sensitive binary fluids contribute to the useful application of this energy resource on a much wider scale.
This book focuses on all aspects of low enthalpy geothermal thermal fluids. It will be an important source book for all scientists working on geothermal energy development. Specifically those involved in research in developing countries rich in such thermal resources, and for agencies involved in bilateral and international cooperation.

Guidance on the practical aspects of fabrication which influence the efficient design of steel bridges. Extensive consultation has taken place with experts in the design, fabrication and erection of steel bridges and, there, this publication represents a compilation of many years' knowledge and experience. Steel designs based on these concepts have proved competitive against more traditional designs.

This book provides practical advice on the issues that affect the efficient detailing of steelwork connections. There is always pressure in the design office to produce details which convert the client's aspirations in to nuts and bolts. The chapters on connection detailing, cost, simple design and basic fabrication give advice on how to create practical structures. Other chapters provide the reader with an insight into connection behaviour and the on-going developments in the "green books". The reader is brought up-to-date on developments in specialist areas of steelwork design and details. These include articles on bridgework, hollow section joints, tension connections, towers and masts and the recent developments with structural fasteners. The publication also contains a rich array of architectural details from actual structures and allows both engineers and architects to interrogate them.

Yan Xiao “Modern Bamboo Structures: Proceedings of the First International Conference"
Taylor & Francis | 2008-08-12 | 312 pages | PDF | 8.45 MB
Bamboo materials are well available in the world. Bamboo has much shorter maturity than trees, thus can be harvested with shorter cycles of plantation. Despite the fact that human society has a long history of using bamboo, there is still a lack of modern and industrialized application of bamboo materials in construction. Promoting the application of bamboo in construction could provide a potential solution to the sustainable, green and environment-friendly development of construction industry.
"Modern Bamboo Structures" is the first of its kind covering the applications of bamboo materials in modern structures. The following topics are covered in this book: properties of bamboo materials and components; design, experimental testing, and analysis of bamboo structures and components; modern bamboo buildings and bridges; composites of bamboo, timber and other materials; bamboo reinforced concrete; comparative studies of timber and bamboo structures; adhesives, joints, and engineered bamboo products; environmental, sustainability and ecological issues; and, structural and constructional applications of other natural and non-conventional materials. These proceedings of the First International Conference on Modern Bamboo Structures (ICBS-2007, Changsha, China, 28-30 October 2007) include the state-of-the-art on materials, design, analysis, testing, manufacturing, and construction of modern bamboo structures. "Modern Bamboo Structures" will be essential for researchers, engineers and administrators involved in structural engineering, civil engineering, agriculture engineering, forestry, environmental engineering and urban development.

Toward Earthquake-Resistant Design of Concentrically Braced Steel-Frame Structures
info:
In recent years, typical steel construction in regions of high seismic risk has shifted from
moment-resisting frames to concentrically braced frames. As a result of the increased popularity
of braced frames, the poor performance of some conventionally braced frames in past
earthquakes, and the limited experimental data available on the inelastic response and the failure
characteristics of braced-frame systems, a series of experimental and analytical investigations
were initiated. The tests reported on herein contain some of the first data available on braced
frames constructed in accordance with modern construction practices in the western U.S.
Extensive analytical studies were undertaken to assess the analysis methods used for the
research, and improved models were developed to better understand the complete range of
behavior, including yielding, lateral buckling, and rupture due to low-cycle fatigue.
The primary objectives of this research are to (1) improve understanding of the behavior
of this common type of structural system under cyclic inelastic deformations, (2) permit
validation and improvement of computer models for predicting global and local response, and (3)
improve understanding of the relation between system, member, and connection behavior.
As such, a series of investigations have been conducted, aimed at understanding and
improving the seismic performance of concentrically braced steel-frame structures. Extensive
analytical studies have been carried out on systems with conventional and buckling-restrained
bracing. Tests on a limited number of full-scale pipe and square, hollow structural section (HSS)
braces were carried out. These tests were supplemented with large-scale tests of three bucklingrestrained
braced-frame (BRBF) specimens and a single two-story special concentrically braced
frame (SCBF). In the latter case, specimens incorporated traditional bracing elements susceptible
to lateral and local buckling. These component and system test results, along with existing data,
were used to develop, calibrate, and validate improved numerical models capable of realistically
simulating the behavior of braced frames, including possible failure due to buckling and lowcycle
fatigue. An array of numerical simulations assessed the likely performance of braced-frame
structures subjected to severe earthquakes of the type expected in California. The applicability of
performance-based earthquake engineering evaluation methodologies to concentrically braced
frames is assessed using these results. Based on this research, recommendations are offered
regarding the design, analysis, modeling, and detailing of concentrically braced frame structures.
