Seminars, Workshops and Conferences
April 8, 2003: The School of Civil Engineering is holding a seminar
entitled The Design and Construction of the Bridges across Storebelt (Great Belt) and Øresund in room E - 220< SCE Building. The seminar will be conducted by Niels J. Gimsing, Professor, Advisor on Bridge Technology, Department of Civil Engineering, Technical University of Denmark.
Abstract
At the end of the 20th Century the largest European bridges of the century were constructed as parts of the 18 km long fixed
traffic link across Storebælt (Great Belt) between the western and the eastern parts of Denmark, and the 16 km long traffic link
across Øresund between Denmark and Sweden.
In both of the traffic links a combination of bridges, tunnels and artificial islands/peninsulas had to be used to transfer both major railway lines and expressways forming a part of the Intereuropean infrastructure. Also, local conditions such as the location of the Copenhagen international Airport in the vicinity of the Øresund Link had an influence on the choice between bridge and tunnel.
Both the 6.8 km long East Bridge of the Storebælt Link and the 7.8 km long Øresund Bridge had to cross international navigation routes from the Baltic Sea to the North Sea. As no obstruction to the existing ship traffic would be allowable neither
in the construction phase nor in the final stage the bridges had to be designed with record-long spans.
The seminar will present the general aspects of optimizing the design and addressing the special problems related to safeguard against accidental ship collisions and hazardous aerodynamic phenomena.
In the construction phase the contractors had to face the problems of working at open sea without obstructing the intense ship traffic. That made it necessary to construct equipment of unprecedented size allowing erection of precast and prefabricated elements with weights of over 6000 tons.
The bridges across Storebælt and Øresund were completed in 1998 and 2000, respectively.
About Speaker
Niels J Gimsing holds the professorship of steel structures and bridge design at the Department of Civil Engineering, Technical University of Denmark.
During various feasibility studies and preliminary design activities in the period from 1970 to 1985 he worked as technical adviser on the design of a fixed traffic link across Storebælt (Great Belt) between the western and the eastern part of Denmark. From 1988 to 1998 he participated in the final design and supervision of the link's East Bridge - the second longest suspension bridge in the world.
In 1993 he joined the design team of the ASO Group in the competition for a fixed traffic link across Øresund between Denmark and Sweden. After the competition design by the ASO Group had been chosen for the actual construction of the Øresund Bridge he was involved in the detailed design of the 7.8 km long bridge for both road and railway traffic.
Niels J Gimsing is the author of the monograph 'Cable Supported Bridges' that has appeared in two English editions as well as
in a Japanese and a Chinese edition. He is also the editor of the Technical Publications (East Tunnel, West Bridge, East Bridge, Concrete Technology) published by the Storebælt organisation, and the Technical Publications (Bridge, Tunnel, Dredging & Reclamation) published by the Øresund organisation.
Besides his involvment in the large bridges in Denmark, Niels J. Gimsing has acted as review panel member during preliminary design of bridges across the Messina Strait in Italy and the Gibraltar Strait between Spain and Morocco, as well as during detailed design of the Tsing Lung Bridge and the Stonecutters Bridge both in Hong Kong.
Interested persons are cordially invited. Students in Structural Engineering and Construction Program are expected to attend. For further details, please contact Dr. Pennung Warnitchai at 0-2524-5530 or Ms. Woranuch at 0-2524-6052.
April 8-9, 2003: The Urban Management Centre - UEM Field of Study and The Comparative Urban Studies Project (CUSP) of the Woodrow Wilson International Centre for Scholars (WWC) Washington D.C. USA are organizing a two day conference on 'Youth, Poverty, and Conflict in Southeast Asian Cities' at the Asian Institute of Technology, Bangkok, Thailand.
The objectives of the conference are:
- to foster a better understanding of the conditions with regard to youth, poverty and conflict in cities in Southeast Asia;
- to call attention to successful and replicable strategies and programs for alleviating predicaments and problems with regard to youth, poverty and conflict;
- to highlight how government agencies, civil society, the private sector, international development agencies and academic institutes can work together on this issues.
Faculty, student and staff are welcome to attend. Interested persons must contact the Urban Management Center at tel. extension 5699/ 5777.

Introduction
Nowadays there exists an obvious trend in the modern aerospace, car and ship building industries to replace 3-axis milling with 5 or even 6-axis machining. The well-established advantages of multi-axis milling such as the high material-removal rates and improved surface finish, allow for a substantial improvement in the accuracy of cutting operations as well as reduction of time required to manufacture complex shaped parts.
It is of paramount importance to develop software focusing on issues surrounding the efficient 5-axis implementations such as tool-path tracing, dynamic display of all moving elements and realistic solid modeling of the material removal.
In Thailand there exists a number of companies and research laboratories in which 5-axis milling has been actively used and analyzed. However, in spite of a variety of conferences and seminars on manufacturing there has been rarely an event specifically focused on 5-axis milling.
Therefore, the main goal of the seminar is to invite the Thai 5-axis machining community including the users, the software vendors and the researchers, to establish cooperation and exchange ideas.
Objectives:
- Introduce 5-axis CAD/CAM
- Discuss requirements of the industry
- Introduce 5-axis applications for Thai industry
- Present 5-axis research at AIT/SIIT
