The earth quakes again in Turkey
Within the interval of few days, we have witnessed series of earthquakes. First Haiti, second Chile and again Turkey. Could this be a coincidence or normal chain of events? Are the earthquakes related to one another?

Product Description:
Eurocode 2 is the key document for future structural design in concrete throughout Europe. To use the Code effectively, structural engineers need a range of aids in the form of flow charts, design charts and simplified procedures. This book provides all of these, and is written with the authority of collaborative work by members of the Concrete Societies of the UK, the Netherlands and Germany. The preparation of the book has been funded under the SPRINT European Community programme for innovation and technology transfer.

Underwater Welding of Offshore Platforms and Pipelines
Underwater Welding of Offshore Platforms and Pipelines
American Welding Society | English | ISBN 0871712156 | 188 pages | PDF | 9.62 MB | 1981
It is not the intention of this paper to elaborate on the history of diving and its progression from shallow air diving through surface mixed gas and eventually to that mode known as saturation. However, the majority of hyperbaric welding being performed is by saturated diver/welders, and, for the benefit of those who are not familiar with the expression "saturation diving," a brief explanation is in order (ISBN-13/EAN: 9780871712158)
Down through the centuries, technology has decreased step by step the limitations of diving, but probably more in the past decade than ever before. The original limitations were very basic things, such as how long could one hold one's breath, how deep could one breathe with a snorkel, and how long could one survive on the air contained in a diving bell. The first real breakthrough occurred around the turn of the 19th century with the invention of the air pump and the closed deep sea diving rig by August Siebe in 1837. Today, however, there are many methods of diving employed in offshore oil fields, depending upon the nature of work, the depth of water, and the required bottom time. This paper will deal basically with the rather recent and rapid progression of deep diving over the past decade and a half and its relationship to the advancement of hyperbaric welding.

SEISMIC ZONING OF KARACHI AND RECOMMENDATIONS FOR SEISMIC DESIGN OF BUILDINGS
Preface
For the seismic design of buildings, structural engineers in Karachi after selecting Moderate Seismic Risk Zone-2 from Geological Survey of Pakistan Maps have been using Uniform Building Code (UBC) for calculating gravity and earthquake loads and carrying out the analysis of the structural frames. Having determined the stress resultants and deformations from the analysis, the design and detailing of reinforced concrete are done in accordance with the requirements of the procedure of seismic design in ACI-318 or Chapter-I 9 of UBC. For other structural materials like steel, timber orstructural masonry, UBC or their respective Codes are used for sizing of the building members. Since 1984, Moderate Seismic Risk equivalent to UBC Zone-2 has been adopted for Karachi by the building designers. The Structural Department of Karachi Building Control Authority (KBCA) has approved the above procedure as the Acceptance Criteria for the structural design and drawings.

I'm looking for sample design calculation notes on the design of pipe arch (elliptical), and arch shaped culverts in both (or) concrete and steel. I've read the previous topics on box culverts and have a solution formed for this type... However, I'm having difficulty analysing the above shapes with regard to soil loads acting on the structure (because of their shape) and the resulting bending moments and shear forces.
Also, I'm using GSA to model these structures and comfirm my calculations. How would you suggest modelling the soil strucure in open arch and pipe arch culverts.
I'm designing to British Standards but any relevant info would be great. I've searched everywhere online!
