TUCSON, Ariz. — Professor Achintya Haldar of the UA civil engineering and engineering mechanics department has been made a distinguished member of the American Society of Civil Engineers.

Distinguished ASCE members are elected by the ASCE board of directors based on their global reputation of outstanding leadership and research in engineering. In the society, the honor is second only to becoming ASCE president.

Each year one in 7,500 ASCE members can be made distinguished members, and just 615 distinguished memberships have been conferred since the society was founded in 1852. Haldar will be formally inducted as a distinguished member in October 2012 at ASCE’s 142nd annual conference in Montreal, Canada.

Haldar’s citation by ASCE refers to his exemplary 44-year career as a world-class researcher, and his work as a peerless educator, mentor and innovative practitioner.

The ASCE noted that Haldar’s work had fundamentally changed structural engineering research, education and practice. His work with industry includes proposing maintenance strategies for a major transit system, developing methods to assess the effects of missile impacts on nuclear power plants, and designing methods to improve the reliability of river navigation systems.

Haldar’s research includes earthquake engineering and mathematical methods for determining structural reliability. In particular, he is interested in computer-based simulation and analysis of structures to determine how they react to different loads and stresses.

The massive amounts of number crunching required by conventional simulation methods could take years for computers to churn through, so Haldar applies theoretical mathematical methods to minimize computer run times.

This enables him to conduct millions of analyses in a matter of days and creates a more statistically accurate picture of how a structure has been damaged, for instance, by an earthquake or by the wear and tear of old age.

He is currently editing a book on this area of research, titled Health Assessment of Engineered Structures: Bridges, Buildings and Other Infrastructures. "Our structures, buildings, they are aging," Haldar said. "And we do not have the money to fix them." Measuring the extent of structural damage is also crucial in determining how badly, and precisely where, earthquakes have damaged new buildings.

The ASCE also noted Haldar’s outstanding teaching and mentoring. He has received excellence in teaching awards from Georgia Tech and the University of Arizona, and recognition from Illinois Institute of Technology.

He has advised many doctoral and master’s students, some of whom have themselves become highly respected faculty members at academic institutions in the U.S., Canada, Korea, Mexico, Taiwan and Jordan.

Haldar got his doctorate in 1976 and his master’s in 1973, both in civil engineering and both from the University of Illinois at Urbana-Champaign. He got his bachelor’s degree in civil engineering in 1968 from Jadavpur University in Calcutta, now Kolkata, India.

During his 24 years in the College of Engineering, Haldar has received dozens of UA awards. In 2011 several professional engineering societies jointly named him Southern Arizona Engineering Educator of the Year.

In 2007 Haldar received an honor from his native country, where the Nonresident Indian Welfare Society in New Delhi selected him to receive the Hind Rattan Award. Hind Rattan is Hindi for "Jewel of India." This private but influential society makes the award to members of the Indian diaspora for outstanding services, achievements and contributions.
