The only modern guide to all aspects of practical tunnel construction
Practical Tunnel Construction fills a void in the literature for a practical guide to tunnel construction.
By taking the reader through a brief introduction and history to a comprehensive discussion of how the geological factors affect tunneling, the author covers the stages and technology that are common today without using complex equations. Written for the individual who does not have an extensive background in tunneling but who has to make tunneling decisions, the various tunneling methods are discussed to help in the determination of the appropriate method. The methods discussed are: hand mining, drill/blast, Tunnel Boring Machine (TBM), New Austrian Tunnelling Method (NATM), Norwegian Method of Tunnelling (NMT), Roadheader, Earth Pressure Balance Machine (EPBM), and Slurry Pressure Balance Machine (SPBM). This book focuses on driven tunnels.
This versatile handbook:
• Offers clear and accessible coverage of the state of the art in tunnel construction
• Introduces the essentials of design and construction of many types of tunnels, including TBM, EPB, Roadheader, NATM, drill and blast, and soft ground tunneling
• Provides nontechnical guidance on selecting the most appropriate tunneling methods for various situations
• Includes a brief history of tunneling and an introduction to geotechnical considerations
• Discusses tunnel access shaft construction, mucking methods, tunnel haulage, grout, water handling, and much more
Practical Tunnel Construction is an important resource for students, construction managers, tunnel designers, municipal engineers, or engineers who are employed by government agencies or corporations that are exploring the feasibility of planning and designing or building a tunnel.

An Introduction to cable roof structures - 2nd Edition
Author: Hans Anton Buchholdt | Size: 10.5 MB | Format:PDF | Quality:Unspecified | Publisher: Thomas Telford Ltd | Year: 1987 | pages: 304 | ISBN: 9780727726247
The second edition of this book provides structural engineers with a concise introduction to the architectural, structural and technological aspects of cable roofs, and supplies sufficient information for engineers to carry out their own designs. The improved methods for generating wind and earthquake histories have been included as the trend in modern design codes seem increasingly to require that dynamic response of other forms of non-linear structures such as guyed masts is considered at the design stage. Other additions include an expansion of the chapter on dynamic analysis into three separate chapters, one dealing with frequency domain analysis of weakly non-linear structures, another with time domain analysis of more non-linear structures, and a third with the level and mathematical modelling of damping.

Dear Engineers,
I am looking for Lithuanian standards but I can't find anything. Maybe You have scans or photos of papers (national annexes of LST EN for example).
If not, maybe someone could give me information about snow and wind loads in Lithuania.
I am using Eurocodes but It would be good if You have even old standards.
Thanks a lot!
FIP Model Code 2010 - Final draft - Bulletins 65 & 66
fib Bulletin No. 65 & 66
Title: Model Code 2010 - Final draft, Volumes 1 & 2
Category: Draft model code
Year: 2012
Format approx. DIN A4 (210x297 mm)
The Model Code for Concrete Structures is intended to serve as a basis for future codes. It takes into account new developments with respect to concrete structures, the structural material concrete and new ideas for the requirements to be formulated for structures in order to achieve optimum behaviour according to new insights and ideas. It is also intended as a source of information for updating existing codes or developing new codes for concrete structures. At the same time, the Model Code is intended as an operational document for normal design situations and structures.
This edition of the Model Code gives an extensive state-of-the-art regarding material properties for structural concrete. This includes constitutive relations for concrete up to strength class C120, and properties of reinforcing and prestressing steel, including prestressing systems. Special attention is given to the application of fibre concrete for structural applications, the application of non-metallic reinforcement, interface characteristics, verification assisted by numerical simulations, verification assisted by testing, and to a number of important construction aspects.
The Model Code 2010 is more 'life cycle' oriented than its predecessors. Reliability plays an important part: various methods are offered to cope with this aspect. The design of concrete structures is described for a large number of conditions. Design criteria are given with relation to reliability, functionality, durability and sustainability, where the last category is in the state of development. The chapter on conservation of structures provides insights into the degradation of concrete as a function of various types of environmental conditions. Attention is given to non-traditional types of reinforcement as well, like steel fibres and FRP, which have reached a status of recognition in the previous years.
Design rules for serviceability and ultimate limit states are given for a wide range of conditions, such as static and non-static loading (fatigue, impact and explosion, earthquake), high and low temperatures (fire and cryogenic). Furthermore limit states for durability are given. Design for sustainability will be an important task in the future; here some initial ideas are given. Design for robustness is also given due attention.
This document is following the first complete draft of the fib Model Code 2010.

JSCE Standard Specifications for Concrete Structures - Materials and Construction
Author: TC | Size: 4.74 MB | Format:PDF | Quality:Original preprint | Publisher: Japan Society of Civil Engineers | Year: 2007 | pages: 490 | ISBN: 9784810607536
The “Standard Specifications for Concrete Structures, Materials and Construction” provides basic general rules concerning the construction of concrete structures. In the construction phase, the construction method and the performance during the construction work are determined based on the design drawings and restrictions on construction. Then, materials are selected and concrete mix proportions are determined, where a concreting plan is developed so as to meet the requirements for water content, cement amount, cement type and other parameters. Whether the concreting plan meets the construction requirements or performance requirements of the structure or not is verified by an appropriate method. If the requirements are not satisfied, the concreting method is re-specified or the mix proportions are modified as long as the conditions handed over from the design phase are met.

To optimise formwork costs and minimise the time for its construction, the contractor needs to understand the guiding principles of safe and efficient formwork construction. He must also have some insight into the relative merits of the various methods, and should appreciate the practical details of formwork construction. This is a practical, heavily illustrated and comprehensive manual for the construction industry. It is equally useful as a text for building students and teachers and trainees. Its large format, and extensive use of line drawings make it clear and straightforward to use.

The first International Workshop on Connections in Steel Structures (Connections I) was held in Cachan, France in 1987, followed by Connections II in 1991 (Pittsburgh, Pennsylvania, USA), Connections III in 1995 (Trento, Italy), Connections IV in 2000 (Roanoke, Virginia, USA), Connections V in 2004 (Amsterdam, The Netherlands) while Connections VI was organized in 2008, in Chicago, USA.
Workshop attendance is by invitation only, and is limited to researchers, designers, fabricators and steel industry representatives with significant expertise in the areas of behavior, strength and design of connections for steel structures. We focus especially on attendance from Europe and North America, since this is how the workshops were initially developed; however, participation of some key persons from several other countries is welcomed. The confirmation of successful organization of these workshops is supported by books published along the six editions, containing 289 scientific papers of very high quality. The results and recommendations have had a pronounced influence on standards, codes and practice in a number of countries. A file with general information about previous Workshops is attached.
The 2012 Workshop will be organized in the historical city of Timișoara, by the "Politehnica" University and the Romanian Academy, under the supervision of ECCS and AISC. The first three days, May 30th and 31st, and June 1st will be devoted for Technical Sessions, while in the last day a tour will be proposed. Additionally, a specific program will be offered for accompanying persons.
As with the previous workshops, Connections VII is co-sponsored by the European Convention for Constructional Steelwork (ECCS) and the American Institute of Steel Construction (AISC).
