Dear all;

Due to do some improvement and upgrading on site, CivilEA temporary unavailable on Friday 13-Apr.
Excuse us for this issue, we will try to do works in short time, my estimation is about 5-6 hours downtime on CivilEA.

Follow us at Facebook, for more information:

Does anyone have the following book:

Non-conventional Concrete Dams on Rock Foundations by Yuri Borisovich Mgalobelov
Taylor & Francis
Jan 1, 1997
281 pages

I will really appreciate if anyone could send me detailed complete calculations and associated drawings for Urban Major Drainage design.

Dear friends I am looking for the paper:

A very brief history of earthquake engineering with emphasis on developments in and from the British Isles

Author: Amr S Elnashai
Publication: Chaos, Solitons & Fractals Volume 13, Issue 5, April 2002, Pages 967–972

Abstract
One of the founders of modern earthquake engineering, George Housner, often states that it is too early to write a historical review of the development of this interesting and inter-disciplinary topic. This is indeed true, but without minor contributions along the line, the prospects of writing such a review diminish with time. The endeavour is certainly premature. Notwithstanding, the paper serves some useful purpose. It serves to remind engineers from Europe generally, and the British Isles specifically, that they are descendants of pioneers in earthquake engineering, a fact not widely known nor sufficiently publicised. The names of Robert Mallet and John Milne, alongside the early Japanese pioneers Sekiya, Suyehiro and Omori, feature very strongly around the late 1800s early 1900s. The Italian engineers Palmieri, Panetti and Danusso also made essential contributions at a critical time. For reasons that still prevail today, once an idea is implanted in the United States of America, it takes root so vigorously that its flourishing is attributed solely to the fertility of the medium. This is not necessarily disputable, but due recognition of the originator would perhaps encourage further cross-fertilisation. The fact still remains that Nathan Newmark, Bill Hall, Bruce Bolt and George Housner all made their mark from a US platform. But, since earthquakes know neither national nor technical-discipline boundaries, seismic risk mitigation efforts should also abandon these boundaries and deploy all means and efforts to protect communities threatened by earthquake risk.
