EN 545:2010 Ductile iron pipes, fittings, accessories and their joints for water pipelines. Requirements and test methods
This European Standard specifies the requirements and associated test methods applicable to ductile iron
pipes, fittings, accessories and their joints for the construction of pipelines outside buildings:
to convey different types of water (e.g. raw water, treated water, re-used water) for all types of
applications (e.g. water intended for human consumption, for fire protection, for snow making, for
irrigation, for hydro-electricity etc.);
with or without pressure;
to be installed below or above ground.
This European Standard is applicable to pipes, fittings and accessories which are:
manufactured with socketed, flanged or spigot ends;
supplied externally and internally coated;
suitable for fluid temperatures between 0 °C and 50 °C, excluding frost;
not intended for use in areas subject to reaction to fire regulations.
This does not preclude special arrangements for the products to be used at higher temperatures.
This European Standard covers pipes and fittings cast by any type of foundry process or manufactured by
fabrication of cast components, as well as corresponding joints and accessories, in a size range extending
from DN 40 to DN 2 000, inclusive.
This European Standard specifies requirements for materials, dimensions and tolerances, mechanical
properties and standard coatings of ductile iron pipes and fittings. It also gives performance requirements for
all components including joints. Joint design and gasket shapes are outside the scope of this standard.
In addition, reference is made to the minimum performance requirements of couplings, flange adaptors and
saddles manufactured for use with ductile iron pipes and fittings.
NOTE In this European Standard, all pressures are relative pressures, expressed in bars (100 kPa = 1 bar).

The Draft Code of Practice for Demolition of Buildings was first issued in February 1998 to provide guidance on safe and good practices for demolition works and for compliance with the requirements of the relevant provisions of the Building (Administration) Regulations and Building (Demolition works) Regulations relating to demolition works.
Throughout the years since its adoption, the Draft Code has been well received by the practitioners. Besides, they have been offering valuable comments on the use of the Draft Code based on their experience gained from its application. The Buildings Department has considered and adopted their constructive views in the present review of the Draft Code which has thus been refined and adopted as this Code of Practice.
The Code contains basic information for the practitioners on better planning and control when carrying out demolition works. It also includes the latest development of the regulatory control on site supervision for demolishing complex structures. This Code should be read and used in conjunction with the Buildings Ordinance and the aforesaid Regulations when preparing demolition plans for approval by the Building Authority. Users of the Code should exercise their own professional judgement in the application of this Code in selecting the most suitable demolition method.

Hi am looking for this paper: M. Menegotto, P.E. Pinto, Method of analysis for cyclically loaded reinforced concrete plane frames including changes in geometry and nonelastic behaviour of elements under combined normal force and bending, in: IABSE symposium on resistance and ultimate deformability of structures acted on by well defined repeated loads, Lisbon, 1973, pp. 15-22
If anyone can find this paper or similar by the authors I would be gratefull.
STAAD.Pro V8i SELECTseries 2 introduces new enhancements in the analysis and design engine and enhancements to many aspects of STAAD.Pro. This includes new design codes GB 50010, IS456, ACI 318-05 (metric), Norsok N004, additional Finnish and Polish National Annex requirements for Eurocode 3. Enhancements to the Australian AS 4100 and Japanese AIJ steel design module. Integration of the STAAD.foundation, StrucLink and PipeLink. STAAD.Pro V8i SELECTseries 2 is integrated into the free Bentley Structural Dashboard application to act as a launch platform for all the structural products in the Bentley portfolio.

Flexible Multibody Dynamics (Solid Mechanics and Its Applications 176) O. A. Bauchau
Flexible Multibody Dynamics (Solid Mechanics and Its Applications 176)
O. A. Bauchau
Springer English 2010
ISBN: 9400703341
728 pages PDF 8 MB
# Presents a unified treatment of rigid and flexible multibody dynamics
# Includes analysis software
# Advances in computational tools in multibody dynamics are making finite element based formulations increasingly popular
# Many of the multibody dynamics books on the market focus on classical formulations based on rigid body dynamics, floating frame of reference, and modal approximations
The author developed this text over many years, teaching graduate courses in advanced dynamics and flexible multibody dynamics at the Daniel Guggenheim School of Aerospace Engineering of the Georgia Institute of Technology.
The book presents a unified treatment of rigid body dynamics, analytical dynamics, constrained dynamics, and flexible multibody dynamics. A comprehensive review of numerical tools used to enforce both holonomic and nonholonomic constraints is presented. Advanced topics such as Maggi’s, index-1, null space, and Udwadia and Kalaba’s formulations are presented because of their fundamental importance in multibody dynamics. Methodologies for the parameterization of rotation and motion are discussed and contrasted. Geometrically exact beams and shells formulations, which have become the standard in flexible multibody dynamics, are presented and numerical aspects of their finite element implementation detailed. Methodologies for the direct solution of the index-3 differential-algebraic equations characteristic of constrained multibody systems are presented. It is shown that with the help of proper scaling procedures, such equations are not more difficult to integrate than ordinary differential equations.
This book is illustrated with numerous examples and should prove valuable to both students and researchers in the fields of rigid and flexible multibody dynamics.

Understandable Structure, Good Design, Convincing Presentation
How to Write Technical Reports: Understandable Structure, Good Design, Convincing Presentation
Lutz Hering, Heike Hering
Springer
English 2010-09-13
ISBN: 3540699287
300 pages PDF 4 MB
* A practical, step-by-step guide to scientific writing
* Indispensable for students as well as being a useful reference for experienced scientists
* Clear and comprehensible writing
* Includes a chapter on oral presentations
"Writing technical reports" conveys the important and necessary knowledge of writing and presenting technical and scientific work.
It answers typical questions about the formal layout and structure, typically arising during the writing process. In addition, it provides many tips ands tricks as well as examples from the real life. Thanks to it clear and easy writing, the book is perfectly suitable for autodidacts.
This book answers questions of engineering students and practitioners occurring
when writing Technical Reports or preparing presentations on the PC. These
questions refer to contents as well as formal aspects. Such questions occur during
the whole work on the report or presentation from the beginning to the end. Therefore
this book is designed as a guideline or manual „How to write Technical Reports“.
It is ordered by timeline along the process of writing Technical Reports
into the three phases planning, creation, and finishing.This practical guide through technical writing is based on the fifth edition of very successful German book by the same authors.

I just downloaded and installed Seismosignal on my pc to do some small checks in AK Chopra.
The Acceleration-Time graph is coming out as a straight line!!!
Worse of it still, the help menu is clickable but brings nothing up. At least i would have referred it. Any help. Its version 3.3 i guess.
Regards
The Acceleration time graph should not be a straight line!!!!!
I first tried the same data as jacs127 used in his screen shot in vain. All the other graphs are similar to his but only Accn-Time is not. Mine is just at zero!!!!
The Accn -Time graph under time series is not right for me. The one under fourier and power spectra is correct. I think both should correlate.
