This paper describes the foundation design process adopted for the Burj Dubai, the world’s tallest building. The foundation system is a piled raft, founded on deep deposits of carbonate soils and rocks. The paper will outline the geotechnical investigations undertaken, the field and laboratory testing programs, and the design process, and will discuss how various design issues, including cyclic degradation of skin friction due to wind loading, were addressed. The numerical computer analysis that was adopted for the original design together with the check/calibration analyses will be outlined, and then the alternative analysis employed for the peer review process will be described. The paper sets out how the various design issues were addressed, including ultimate capacity, overall stability under wind and seismic loadings, and the settlement and differential settlements.
The comprehensive program of pile load testing that was undertaken, which included grouted and non-grouted piles to a maximum load of 64MN, will be presented and “Class A” predictions of the axial load-settlement behavior will be compared with the measured behavior. The settlements of the towers observed during construction will be compared with those predicted.

Product Description:
Displacement-Based Seismic Design of Structures is a book primarily directed towards practicing structural designers who are interested in applying performance-based concepts to seismic design. Since much of the material presented in the book has not been published elsewhere, it will also be of considerable interest to researchers, and to graduate and upper-level undergraduate students of earthquake engineering who wish to develop a deeper understanding of how design can be used to control seismic response.

Bus Systems for the Future«Achieving Sustainable Transport Worldwide»

Rapidly increasing traffic congestion, air pollution, and sprawl are jeopardising the ability of the developing world’s premier cities to achieve sustainability. These problems, present in most large urban areas of developing countries, also account for a substantial share of the expected increase in world oil use and CO2 emissions over the next twenty years. Near-term bus system improvements in these cities – before cars become dominant – could be among the most important and most cost-effective approaches for achieving transport sustainability. Compared to urban transport systems dominated by private vehicles, bus-dominated systems result in much less traffic congestion, lower energy use and emissions, and improved mobility for all social and economic classes.
