Imperial College London Library
On the 22nd August I went to a university library to read their books on engineering in earthquakes. This was a daunting idea at first, but i managed to pluck up the courage to go and it turned out to be an extremely useful thing to do. I intend to go again, either to the same library or a different London university Library.
I took notes from three different books which i sourced:
I took notes from three different books which i sourced:
- Introduction to Earthquake Engineering, second edition, Shunzo Okamoto, University of Tokyo Press,copyright 1984
- Design of Earthquake-resistant Buildings,Minoru Wakabayashi, McGraw-Hill Book Company USA, copyright 1986
- Urban Disaster Mitigation- the role of engineering and technology, Elsevier Science Ltd, copyright 1995
These books gave me background knowledge to my project, but now i need to research in depth the two cities i have decided to research for my essay, and then start writing my essay.
Cambridge Summer School
At the beginning of August I attended a residential Mechanics summer school at Cambridge university in which I learnt new equations and concepts to do with dynamics; harmonic motion, circular motion, rotational dynamics.
This was indirectly relevant to my topic; the motion caused by earthquakes to buildings can often involve these calculations. I will not need to know this knowledge to write my essay, however when researching, I will be able to understand more of the mathematics behind what happened to the structures during the earthquakes as this will no doubt be recorded in studies and in the university books.

Timeline
July 8th:
- google topic to get overview of people and theories involved in structures in earthquakes and the people involved in the structures of the two cities that I am studying
- make Gantt chart
July 9th- 17th:
-read my books on why structures fail whilst on holiday
July 18th- 22nd:
- Work experience with Sir Robert McAlpine engineering company
August 1st- 5th:
- spend time in the Imperial library researching structures in earthquakes
- find programmes about Hiroshima earthquake in Japan (2011) and articles on Sumatra earthquake in Andaman Islands (2004) to start my research for essay
End of August:
- hopefully get work experience with Arup around this time
- continue with research
September 1st - 6th:
- begin writing essay, by coallating all research
possible cities to compare
At my residential this week at Imperial I had a lecture on Earth science and was able to pick up some information for my project on Earthquakes.
The Sumatra earthquake of 2004 is of magnitud 9.3, similar to Japan's Hiroshima of magnitud 9 on the richter scale. They both suffered an earthquake and tsunami and are therefore similar situations. Sumatra however was in 2004 so it might be interesting to discover how/ if buildings have improved over 7 years.

Damping
I have been researching a method of relieving the stresses in a structure when subject to earthquakes. This method is called damping and I found a great source: http://www.taylordevices.eu/pdfs/seismic%20applications.pdf (accessed 30th June 2011, 10.00am )
