Topic: Railroads and Environment – Steps in Locomotive and Power Development to Improve the Environmental Footprint of Rail Transportation

Presenter: Mike Iden – General Director, Car and Locomotive Engineering, Union Pacific Railroad
(hosted by Pasi Lautala)

Abstract: Railroads and rail transportation is often considered the “green” transportation alternative, but there is never-ending development process toward improving both the energy efficiency and the environmental footprint of rail transportation. One of the greatest priorities has been locomotives, whether it has been in reducing emissions or in improving operational practices toward better fuel consumption. This presentation will review some of the latest and future advances related to the development of north American diesel locomotives that today dominate the market. The difference between on-board power (diesel-electric or other prime movers) versus centralized power (“electrification”) will also be discussed, including technical and economic issues.

Topics:

1. Integration of Mainshock-Aftershock Sequences Into Performance-Based Engineering
Presenter: Ruiqiang Song, Ph.D. Student, Department of Civil and Environmental Engineering, (Adviser: Dr. Yue Li)

Abstract: During earthquake events, it is very common to observe many aftershocks following the mainshock. Although they are normally smaller in magnitude, aftershocks may have a large ground motion intensity, even longer duration and different energy content. Aftershocks have the potential to cause severe damage to buildings and threaten life safety even when only minor damage is present from the mainshock. However, most of current seismic risk assessment researches focus on risk due to a mainshock event only. The primary goal of this research is to systematically integrate aftershock seismic hazard into Performance Based Engineering through a combination of analytical studies with structural degradation models. In this study, the global-level hysteresis damage models is calibrated, structural Collapse Capacity subjected to Mainshock and aftershock sequence is carried out by performing incremental dynamic analysis, the effect of frequency content on structural collapse capacity are also checked and ground motion attenuation relationship of response spectral values are presented.

2. Building Information Modeling: A Demonstration of Parametric Modeling and its Use in the Construction Industry
Presenter: Christopher Brokaw, Master student, Department of Civil and Environmental Engineering, (Adviser: Dr. Amlan Mukherjee)

Abstract: Building information modeling (BIM) is a type of software that can be used to create a 3D model of a construction project that integrates information about the materials and scheduling. This makes it is possible to quickly explore multiple alternate designs and evaluate their performance, as well as plan out the entire project and management strategies. This allows for improved information management and project control when compared to projects designed with 2D drafting software. In this presentation, I will use a hands-on demonstration to explore BIM software and illustrate how stakeholders can use this software to streamline the design process, reduce conflicts, and save money. I will also present an overview of my ongoing research project that, in addition to the above, will explore the benefits of transitioning to BIM software, and will show some of the lessons learned from the early adopters.

NSBE team takes Family Engineering to Detroit

Members of Michigan Tech’s chapter of the National Society of Black Engineers (NSBE) are in Detroit to participate in an alternative spring break 2012 week. Eight members of the Michigan Tech student chapter of the NSBE will visit six middle schools and one high school to talk with students. They will also conduct Family Engineering events at three schools. Family Engineering includes fun, hands-on activities for the whole family, such as “Mining For Chocolate” and “Glue Is The Clue.” The program, developed at Michigan Tech and now available across Michigan and nationwide, is designed to engage and inspire young people and their families to consider careers in engineering and science.
