I am researching and designing the onshore wind turbine foundation and its behaviour on soils (Influence of wind turbine foundations action on soils) and would like to ask some advices and recomendations.
Maybe could anybody to recomend and advice some literature or give other information where i could to find:
- about wind loads and its influence for foundation (dynamic loads);
- about natural frequency of construction and its evaluation;
- about soils characteristics and its evaluation (dynamic modulus of stiffness and etc.);
- about designing of foundations and etc.
All information is useful for me about onshore wind turbines.
Preliminary information on the recorded strong ground motions during the 2011 Off the Pacific Coast of Tohoku earthquake available in the following link:

LOAD AND RESISTANCE FACTOR DESIGN SPECIFICATION 1999
Author: AMERICAN INSTITUTE OF STEEL CONSTRUCTION (AISC) | Size: 2.332 MB | Format:PDF | Publisher: AMERICAN INSTITUTE OF STEEL CONSTRUCTION (AISC) | Year: 1999 | pages: 327
The AISC Load and Resistance Factor Design (LRFD) Specification for Structural Steel Buildings is based on reliability theory. As have all AISC Specifications, this Specification has been based upon past successful usage, advances in the state of knowledge, and changes in design practice. This Specification has been developed as a consensus document to provide a uniform practice in the design of steel-framed buildings. The intention is to provide design criteria for routine use and not to provide specific criteria for infrequently encountered problems, which occur in the full range of structural design.
This Specification is the result of the consensus deliberations of a committee of structural engineers with wide experience and high professional standing, representing a wide geographical distribution throughout the U.S. The committee includes approximately equal numbers of engineers in private practice and code agencies, engineers involved in research and teaching, and engineers employed by steel fabricating and producing companies.
The contributions and assistance of more than 50 additional professional volunteers working in 15 task committees are also hereby acknowledged. The Symbols, Glossary, and Appendices to this Specification are an integral part of the Specification. A non-mandatory Commentary has been prepared to provide background for the Specification provisions and the user is encouraged to consult it. The principal changes incorporated in this edition of the Specification include:
• Dual units format. Values and equations are given in both U.S. customary and metric units. The metric conversions (given in parentheses following the U.S. units) are based on ASTM E380, Standard Practice for Use of the International System of Units (SI). The equations are non-dimensionalized where possible by factoring out material constants, such as E and G.
• Inclusion of new structural steels ASTM A913 and A992.
• Additional notch toughness requirements for complete-joint-penetration groove welds with tension applied normal to the effective area.
• New provisions for stability bracing of beams, columns, and frames.
• New Chapter N for evaluation of existing structures.
• Revised provisions for member design under fatigue loading in Appendix K.
• Reorganization of material on pin-connected members and eyebars.
• Revised provisions for concrete-encased beams.
• New limitation on the stud reduction factor when a single stud is used in a rib.
• Revised bolt bearing strength criteria.

Waste Water Treatment and Reuse in the Mediterranean Region (The Handbook of Environmental Chemistry)
Waste Water Treatment and Reuse in the Mediterranean Region (The Handbook of Environmental Chemistry)
Author(s): Damia Barcelo and Mira Petrovic
Publisher: Springer
Date: 2011-01-11
Format: pdf
Language: English
ISBN10: 3642182801
Pages: 300
ISBN13: 9783642182808
Product Description:
Water scarcity and the need for ecological sustainability have led to the introduction of treated waste water as an additional water resource in the national water resource management plans of Mediterranean countries. Summarizing the results generated within the European Union-funded project INNOVA-MED, this volume highlights the following topics:
*
Application of innovative technologies and practices for waste water treatment and reuse adapted to the Mediterranean region
*
Constraints on the application of advanced treatments and reuse of reclaimed water and sludge
*
Problems and requirements of sustainable water management in the Mediterranean area
The book includes several examples of Mediterranean countries, such as Tunisia, Morocco, Egypt, Palestine and Spain, and presents their practical experiences in the application of innovative processes and practices for waste water treatment and reuse.

The scope of this Structure Study is to document the development process for the preferred alignment of the main bridge crossing the Detroit River including both the main structure over the river and the U.S. approach structure. The Canadian members of the Border Transportation Partnership will perform further development of the Canadian approach structure later. For the recommended project alternative, or Preferred Alternative, two bridge types, suspension and cable-stayed, are advanced for further development in this Early Preliminary Engineering phase.

Mechanical Vibrations and Shocks: Sinusoidal Vibrations (Volume 1)
Kogan Page Science | February 14, 2002 | ISBN-10: 1903996031 | 320 pages | PDF | 4.28 MB
This volume is from the "Mechanical Vibration and Shock" five-volume study. The relative and absolute response of a mechanical system to one degree with freedom is considered for arbitrary excitation, and its transfer function defined in various forms. The characteristics of sinusoidal vibration are placed in the context both of the real world and of laboratory tests, and transient and steady state response of the single-degree-of-freedom system. First viscous damping and then non-linear damping is considered. The various types of sine-sweep and their properties are described and, for the one-degree-of-freedom system, the consequences of an inappropriate choice of sweep rate are considered. From the latter, rules governing the choice of suitable sweep rates are developed.
