Abstract: The Brazilian territory presents low seismicity, typical of a tectonic intra-plates region. However, at least two Brazilian regions have non-negligible seismicity: part of the Northeast Region, due to its proximity to the South Atlantic Ridge and the Brazilian Occidental Amazon, due to its proximity to the Pacific Plate border. Due this low seismicity, up to 2006 Brazil was practically the only South-American country without a seismic standard. Considering the already gathered seismological information and the theoretical studies recently performed, it has been progressively recognized that seismic effects cannot be disregarded in the structural design in Brazil. Then, in 2006, the new Brazilian Standard for the Design of Seismic Resistant Structures was concluded and issued. The seismological data, the considered probabilistic methodology and the probabilistic studies developed for defining the nominal values of horizontal accelerations in the several Brazilian regions are presented. Some aspects established in the Standard for the design of building structures are also commented.

Find 2008 (Finland + India) aims to extend already existing business relations between India and Finland, enhance awareness of the rising business opportunities that emerging new technologies have to offer and how to utilize them. The conference provides an exceptional platform for facilitating collaboration, partnerships and investments between Finland, India and third parties. This is portion of the presentation of Pekka Pulkkinen (WSP).
Once completed, the Chenab Bridge – at 1315 meters long and 359 meters high – will be the tallest Railway Arch Bridge in the world. As part of the Jammu-Udhampur-Srinagar-Baramulla Rail Line (JUSBRL), the bridge will cross over the deep gorges of the Chenab River and connect the Kashmir valley with Udhampur. The railway line itself, which has been taken up as a National Railway project will for the first time connect Kashmir to the rest of India. The bridge is designed as a massive steel arch – a first in India. To resist the challenge of hostile weather, the steel being used will withstand temperatures as low as -20C and wind speeds of 200 kmph, while being economical in cost. Forces of nature apart, the engineers also face the challenge of construction in one of the most complicated and isolated terrains, while also ensuring that the flow of the river is not disturbed.
Contents of the presentation:
1. Basic Information of the Project
2. The Bridge Site
3. Scope of Design Work
4. Description of the Bridge
5. Experiences of Cooperation between Design Consultant, Authorities and Indian Contractors
6. Conclusions

That book underscored the practice described in Strakosch with mathematical and computer analysis. Although the content of the book remains valid today, other authors have entered the field and have contributed to the theory and practice of lift traffic design and control.
In this book, I have attempted to bring together in one place a complete treatment of elevator traffic design and control. In addition to my work in the subject, the book draws on the work of other authors in the field, which I have included, commented on, extended, agreed with, or disagreed with. The interpretations are mine, as are the mistakes.
The early chapters concern well-established practice that is generally accepted. The latter chapters contain a more philosophical discussion and present controversial aspects that may require further refinement. I would like any comments and challenges to come to me in this continuing debate. Contact details are at www.liftconsulting.org.
My career has lead me through industry, research, teaching, consulting, code making and training. I have written this book for everyone involved in traffic design and traffic control of lift (US: elevator) installations. I have based it on theory arising out of practice. Lift traffic design is a practical science.

Abstract: Working closely with Foster and Partners, an astonishing column free base tower was created by supporting the entire weight of the building on only its two end cores. These heavily loaded cores allow the slender tower to efficiently resist wind loads. With a height to width ratio of 11 to 1, this 250 m tower is the ultimate in structural efficiency. To achieve this unique structure, steel trusses at intermediate mechanical levels channel loads from the floors above to the cores and serve as beams in a ‘mega-frame’ to stiffen the tower. Structural redundancy was achieved in the design by considering a failure of any one of the three truss levels. This load case was considered to ensure that total building collapse would not occur if a local failure of a truss where to occur through an accidental or premeditated event.

Energy Modeling and Computations in the Building Envelope instills a deeper understanding of the energy interactions between buildings and the environment, based on the analysis of transfer processes operating in the building envelope components at the microscopic level. The author:
Proposes a generalized physics model that describes these interactions at the microscopic level via the macroscopic characteristics of the building envelope
Presents mathematical models that utilize classical analytical tools and can be used to perform quantitative predictions of the consequences of the energy interactions
Reveals easy-to-apply engineering methods concerning the design and inspection of the building envelope, taking into account the effects of energy on the envelope
Energy Modeling and Computations in the Building Envelope provides comprehensive coverage of this environmentally and economically important topic, from the physics of energy transfer to its numerical estimation. The book is especially useful to those looking to increase building energy efficiency, decrease the consumption of primary energy carriers, and raise the ecological sustainability of construction products.

A Training Tool for the Environmental Risk Professional
Environmental Risk Analysis: Probability Distribution Calculations defines the role that probability distributions play in risk analysis, and gives direction on how to measure and compare the magnitude of risk more efficiently. Designed for the practicing environmental engineer and scientist, this book clearly explains the key fundamentals, principles, and applications of probability distributions in environmental risk analysis.
Based on years of research and the author’s own experience, the book provides nearly 200 illustrative examples utilizing probability distributions, as well as numerous solved problems that involve applications in the manufacturing, chemical, refining, power/utilities, travel/aerospace, pharmaceutical, anti-terrorism/military, and nanotechnology industries. It offers an in-depth discussion of the Weibull distribution, which describes failure rate as a function of time. It also details the author’s recent efforts to improve on Weibull’s work, and covers other continuous probability distributions that can apply to risk assessment/analysis.
The book addresses environmental risk calculations that involve both discrete and continuous probability distributions. It focuses on discrete distributions that include binomial, multinomial, hypergeometric, and Poisson; and continuous distributions that include normal, lognormal, exponential, Weibull, F, and chi-square distribution.
Includes a complete overview of environmental risk and covers environmental risk-related topics
Presents a simplified approach to the industrial application of environmental risk analysis and probability distributions
Offers a practical understanding of environmental risk analysis calculations involving probability distributions
Environmental Risk Analysis: Probability Distribution Calculations provides a working knowledge of the principles and applications needed to solve real-world problems relevant to environmental risk analysis and probability distributions. This book serves as a valuable resource for practicing professionals in environmental science and engineering.
