Abstract:
Longitudinal stiffeners are often attached to increase the buckling strength of thin-walled box girder flanges. The minimum required rigidity for longitudinal stiffeners for curved box girder flanges is given by the AASHTO “Guide specifications for horizontally curved steel girder highway bridges.” However, this requirement is simply adopted from the current AASHTO specifications for straight stiffened flanges. The validity of this requirement has been questioned in a series of recent studies. The effect of important design parameters on the minimum required stiffener rigidity is investigated numerically in this study by examining the prebuckling stress distribution and elastic and inelastic buckling stresses of horizontally curved stiffened flanges. In order to characterize and quantify the analytically collected data, a series of parametric studies were performed. A new equation for the minimum required rigidity for the longitudinal stiffeners is derived from regression analyses. Through the evaluation of a few selected case studies and a design example, the validity and reliability of the proposed new equation is demonstrated.

Hi i need a spread sheet or a small software which can help me building canal cross sections with given data points preferable in CAD format, which will later help in area calculations. Or any other solution related to this problem.
I really need solution. So any kind of help will be appreciated :)
Cheers.. !
The intent of the EERI oral history project is to publish a series of interviews with prominent figures in the field of earthquake engineering to preserve some of the rich history of those who have pioneered in shaping seismic design theory and practice. The Oral History Committee is charged with submitting the names of candidates for this honor to the Board of Directors.
The interviews were initially conducted by the late Stanley Scott, research political scientist at the Institute of Governmental Studies at the University of California at Berkeley, except for the Nicholas Forell and Henry J. Brunnier interviews, which were done by Joseph P. Nicoletti and Frank Killinger, respectively. Scott’s interview of Joseph Penzien was supplemented by Robert Reitherman.
To be the subject of an EERI oral history, individuals must meet the following criteria:
1. have made an outstanding career-long contribution to earthquake engineering,
2. have valuable first-person accounts to offer concerning the history of earthquake engineering, and
3. have backgrounds, considering the series as a whole, that appropriately span the various disciplines that are included in the field of earthquake engineering

Author: Fulco Ludwig (Editor), Pavel Kabat (Editor), Henk van Schaik (Editor), Michael van der Valk (Editor) | Size: 6.50 MB | Format:PDF | Quality:Original preprint | Publisher: Routledge | Year: 2009 | pages: 304 | ISBN: 1844076520
Book Description:
Publication Date: February 26, 2009:
Today's climate variability already has a large impact on water supply and protection. Millions of people are affected every year by droughts and floods. Future climate change is likely to make things worse. Many people within the water sector are aware that climate change is expected to have serious consequences for water resource management, but they are unsure how to incorporate climate information into their management structures. Providing a compendium of specific strategies, Climate Change Adaptation in the Water Sector is the first book to show students and professionals in the water sector how to adapt to climate change and variability. It enables advanced students, managers, decision-makers and other practitioners to feel comfortable in analysing and using climate data within the water sector. The book consists of two parts: the first describes the general issues and is written mainly by the editors of the book, while the second part contains specific case studies drawn from a wide range of contrasting countries: Australia, Germany, The Netherlands, the Philippines, South Africa, Thailand and Yemen. Published in association with the Co-operative Programme on Water and Climate, NeWater, UNESCO and WATCH (Water and Global Change)
Review
'A very timely publication that reflects the current thinking in climate-related water management, and a much-needed contribution to education efforts dealing with global change. Highly recommended to all - students and teachers alike - as a guide to this complex but vital issue!' Professor Richard Meganck, Rector, UNESCO-IHE Institute for Water Education 'I welcome this valuable effort, which sheds light on adaptation options for the water sector as a whole. This is an excellent publication that will be essential to anyone involved in water resources management.' Paul Reiter, Executive Director, International Water Association (IWA) 'Climate change will impact first on water. The water sector worldwide will need to mobilize for climate change adaptation and integrate the needs of both people and nature as it does so. This publication will help water managers meet this challenge.' Dr Mark Smith, Head, Water Programme, International Union for Conservation of Nature (IUCN) 'This book is indeed a very timely publication that reflects the current thinking in climate-related water management as a much-needed contribution to education efforts dealing with global change. Highly recommended to all - students and teachers alike, as a guide to this complex but vital issue!' Professor Richard Meganck, Rector, UNESCO-IHE Institute for Water Education

can someone share an idea in regards to the number 10 in civil/ structural engineering. I have a task to make an educational/proffessional poster - the topic is number 10.
Any idea or interesting fact are welcome!
I was thinking on X bracing (Roman numeral is X), X cracking in walls due to earthquake, magnitude 10 on the Richter scale, crossroad X,...
