Hi,
I am looking for Norwegian National Annexes to Eurocode: NS-EN.
Maybe someone have any and can share?
The most necessary are annexes to the parts of EN 1990, 1991 and 1993 (steel structures, especially 1993-1-1 and 1993-1-8).
Thank You in advance.
The book establishes sewer processes as an integral part of managing, designing, and operating an urban wastewater system. It presents in-sewer processes from a fundamental and conceptual point of view for easy understanding by students. Both engineers and students will find the book's models and practical examples useful. It demonstrates a range of sewer and treatment issues, such as odor control, corrosion, and integrated wastewater treatment. It also explains how environmental process engineering principles can be applied to sewer design, resulting in better wastewater treatment and cleaner water entering receiving areas.
Sewer Processes
Microbial and Chemical Process Engineering of Sewer Networks, 2nd Edition
Sewer Processes: Microbial and Chemical Process Engineering of Sewer Networks, Second Edition, provides a basis for up-to-date understanding and modeling of sewer microbial and chemical processes and demonstrates how this knowledge can be applied for the design, operation, and the maintenance of wastewater collection systems. The authors add chemical and microbial dimensions to the design and management of sewer networks with an overall aim of improved sustainability for the system itself and the surrounding environment.

Random Vibration: Mechanical, Structural, and Earthquake Engineering Applications effectively integrates the basic ideas, concepts, principles, and theories of random processes. This enables students to understand the basic methodology and establish their own logic to systematically handle the issues facing the theory and application of random vibrations.

Dynamics is increasingly being identified by consulting engineers as one of the key skills which needs to be taught in civil engineering degree programs. This is driven by the trend towards lighter, more vibration-prone structures, the growth of business in earthquake regions, the identification of new threats such as terrorist attack and the increased availability of sophisticated dynamic analysis tools.
Martin Williams presents this short, accessible introduction to the area of structural dynamics. He begins by describing dynamic systems and their representation for analytical purposes. The two main chapters deal with linear analysis of single (SDOF) and multi-degree-of-freedom (MDOF) systems, under free vibration and in response to a variety of forcing functions. Hand analysis of continuous systems is covered briefly to illustrate the key principles. Methods of calculation of non-linear dynamic response is also discussed. Lastly, the key principles of random vibration analysis are presented – this approach is crucial for wind engineering and is increasingly important for other load cases.
An appendix briefly summarizes relevant mathematical techniques. Extensive use is made of worked examples, mostly drawn from civil engineering (though not exclusively – there is considerable benefit to be gained from emphasizing the commonality with other branches of engineering). This introductory dynamics textbook is aimed at upper level civil engineering undergraduates and those starting an M.Sc. course in the area.

Abstract:
The effects of water-cementitious materials ratio, age, and aggregate type on the compressive strength, flexural strength, and fracture energy of concretes with compressive strengths ranging from 20 to 99 MPa (2900 to 14,400 psi) are studied. Concrete mixtures contain either basalt or crushed limestone aggregate with maximum sizes of 12 or 19 mm (1/2 or 3/4 in.). Mixtures are tested at ages ranging from 5 to 180 days and have water-cementitious (w/cm) ratios ranging from 0.24 to 0.50. High-strength concrete containing the higher-strength, basalt coarse aggregate attains higher compressive and flexural strengths than high-strength concrete containing limestone. The compressive and flexural strengths of medium and normal-strength concretes (fc¢ up to approximately 60 MPa [9000 psi]) are affected little by aggregate type. Concrete containing basalt yields significantly higher fracture energy than concrete containing limestone, with fracture energy governed principally by aggregate properties, independent of compressive strength, w/cm ratio, and age. Overall, as compressive strength increases, the energy stored in the material at the peak tensile load increases while the ability of the material to dissipate energy remains approximately constant. The result is increasingly brittle behavior as compressive strength increases.
