Civil Engineering Graduate Seminar

Civil Engineering Graduate Seminar: Thursday, April 18, 2013, bRoom 642 Dow Bldg., 4:00 – 5:00 pm
Mr. Aboelkasim Diab Ahmed Ali, a civil engineer from Egypt who is studying toward a PhD at Michigan Tech, will discuss the results of two projects that he has recently completed. They are as follows:
1) A Mathematical Approach Bridging Resilient Moduli to Dynamic Moduli for the Mechanistic Empirical Design of Asphalt Pavements, and
2) Rheology Evaluation of Unaged Foam-based Warm Mix Asphalt Modified with Nano Hydrated Lime.

Billions of people worldwide burn animal dung, crop residues, wood and charcoal to cook their meals. And the chemicals produced and inhaled sicken or kill millions. At particular risk are women who prepare their families’ food and children 5-years-old or younger.

Up to now, most interventions have focused on improving the cookstove to lower emissions. And that would be fine, if there were enough improved cookstoves to go around. But there aren’t. In 2012, only 2.5 million improved cookstoves were distributed, improving the household air pollution situation for exactly one-half of 1 percent of the world’s biomass burners. Continue reading

Two from Tech Among Top 25 Education Professors in Michigan

Joan Chadde, coordinator of education programs for the Center for Science and Environmental Outreach, and Professor Brad Baltensperger, chair of cognitive and learning sciences, have been named among the 25 top education professors in Michigan. The list of top education professors was just released by a nonprofit organization called StateStats, whose mission is to advance education through the use of technology and information tools. StateStats provides education resources online, including lists of professors they have researched and nominated as the best in their profession.

Topic: Design / Construction of a 413 meter highrise building at Kuwait City Sculpted High-Rise – The Al Hamra Tower

Abstract: With a roof height of 413m, the Al Hamra Tower in Kuwait City is amongst the tallest buildings in the world. Setting it apart from other super high-rise buildings is its unique sculpted form. An example of architectural expression through structural form on a grand scale, the structural system and exterior form were developed in a symbiotic digital design process. The building geometry is generated by a spiraling slice subtracted from a simple prismatic volume. The resultant spiraling building form generates a dramatic cantilevered office wing that wraps around an exterior coutyard. The two resultant cut surfaces are hyperbolic paraboloid reinforced-concrete walls, which extend the full height of the tower and participate in the lateral and gravity force resisting systems. Other noteable features include a Nervi inspired lamella structure bracing the tower columns which curve 24m throught the lobby space, and a spiralling roof geometry that extends 90m from low point to high point and encloses a 40m tall skygarden space.

The design of the Al Hamra Tower required consideration of challenging engineering issues complicated by both the height and form of the structure. Long-term creep and shrinkage of concrete was carefully studied to account for force redistributions and to develop an extensive program of displacement pre-corrections to be made during construction. The spiraling hyperbolic paraboloid ‘flared walls’ required for gravity load support of the cantilevered wing apply a torsional gravity load to the building core that necessitates consideration of both the long-term vertical and torsional deformations of the building structure.

Opened in late 2011, the Al Hamra Tower is a dramatic addition to the skyline of Kuwait City and is set to become a major destination for the city. This presentation will focus on both the technical design and construction challenges in the accomplishment of this complex project.
