Найти книгу: "Recommendations on Piling (EA Pfahle)"

This handbook provides a complete and detailed overview of piling systems and their application. The design and construction of piled foundations is based on Eurocode 7 and DIN 1054 edition 2010 as well as the European construction codes DIN EN 1536 (Bored piles), DIN EN 12699 (Displacement piles) and DIN EN 14199 (Micropiles). These recommendations also deal with – categorisation of piling systems, – actions on piles from structural loading, negative skin friction and side pressure, – pile resistances from static and dynamic pile test loading as well as extensive tables with the pile load-bearing capacity of nearly all piling systems based on values from practical experience, – pile groups, – performance of static and dynamic test loading and integrity tests, – load-bearing behaviour and verifications for piles under cyclical, dynamic and impact actions – quality assurance for construction. An appendix with numerous calculation examples completes the work. As part of the approval procedure for offshore wind energy structures, the Federal Office for Shipping and Hydrography (BSH) demands verifications according to the new Chapter 13 («Load-bearing behaviour and verifications for piles under cyclical, dynamical and impact actions») of the EA Pfahle (the recommendations of the Piling working group – 2nd edition), which deals with external pile resistance for the foundations of offshore wind energy structures and the types of verifications to be provided under cyclical actions. The publication of the EA-Pfahle recommendations by the Piling working group of the German Society for Geotechnics (DGGT), which works with the same members as the piling standards committee NA 00-05-07, is intended to provide assistance for engineers active in the design, calculation and construction of piled foundations. The recommendations can thus be considered as rules of the technology and as a supplement to the available codes and standards.

First, you need to understand that the determining factors for any posture are such as: convenience; relative ease of execution; pleasure. Many people do not change their preferences, I use the missionary posture «for all occasions.» It is worth noting that it is one of the most optimal, but the body lovers very quickly get used to it, because of what the amount of pleasure is reduced.

This handbook provides a complete overview of pile systems and their application and production. It shows their analysis based on the new safety concept providing numerous examples for single piles, pile grids and groups. These recommendations are considered rules of engineering.

A thoroughly updated new edition of the essential reference on the design, practice, and analysis of clinical trials Clinical Trials Dictionary: Terminology and Usage Recommendations, Second Edition presents clear, precise, meticulously detailed entries on all aspects of modern-day clinical trials. Written and compiled by one of the world’s leading clinical trialists, this comprehensive volume incorporates areas of medicine, statistics, epidemiology, computer science, and bioethics—providing a treasure trove of key terms and ideas. This new edition continues to supply readers with the A–Z terminology needed to design, conduct, and analyze trials, introducing a vocabulary for the characterization and description of related features and activities. More than 300 new entries are now included, reflecting the current usage practices and conventions in the field, along with usage notes with recommendations on when to use the term in question. Detailed biographical notes highlight prominent historical figures and institutions in the field, and an extensive bibliography has been updated to provide readers with additional resources for further study. The most up-to-date work of its kind, Clinical Trials Dictionary, Second Edition is an essential reference for anyone who needs to report on, index, analyze, or assess the scientific strength and validity of clinical trials.

Since 1949 the «Committee for Waterfront Structures» has operated on honorary base as a committee of the Society for Harbour Engineering (HTG), Hamburg, and since 1951 also as working group of the German Society for Geotechnics (DGGT), Essen. Its full designation reads «Committee for Simplification an Standardization of Calculation and Construction of Waterfront Structures», which also outlines its goals. Following on from the previous joint publications, this new edition of EAU 2004 contains the safety concept with partial safety factors in accordance with the Eurocodes or the European prestandards as well as with the new edition of the corresponding German standard, partially differing on account of practice experiences. The recommendations continue to satisfy the requirements for international acknowledgement and application with regard to planning, design tendering, the awarding of contracts, building and building supervision. Further, the inspection and accounting procedures for harbour and waterway constructions are given from uniform points of view.

The completely revised and extended Recommendations deal with all questions relevant to the planning and dimensioning of geosynthetics-reinforced earth structures. In addition to the demands on materials and analysis principles, the applications of geosynthetics in a range of foundation systems, ground improvement measures, highways engineering projects, in slopes and retaining structures, and in landfill engineering are discussed. The Recommendations have been supplemented by the following sections: – reinforced earth structures over point or linear bearing elements, – foundation systems using geotextile-encased columns, – bridging subsidence, – dynamic actions of geosynthetic-reinforced systems. The remaining sections have been fundamentally revised and updated in line with current standards and codes of practice.
