Presenter: Dr. Yue Li, Donald and Rose Ann Tomasini Assistant Professor of Structural Engineering
Department of Civil and Environmental Engineering, Michigan Technological University
Abstract: Although in many parts of the country one natural hazard
dominates, in certain areas multiple hazards may pose a significant
threat to buildings and infrastructure. Building design and construction
practices should address the overall risk to construction from multiple
hazards to achieve design strategies and risk levels that are consistent
with occupant expectations and social objectives. This presentation
presents a performance-based engineering framework for multi-hazard risk
assessment and mitigation.
Associate Professor Brian Barkdoll will present “Research Ethics” from 4 to 5 p.m., Thursday, Jan. 13, in Dow 642. Issues such as plagiarism, data fabrication and copyright, both for students and faculty, are explored here to help give credit where credit is due and to make sure no disciplinary action is needed. Research ethics is an area of growing concern with the advent of the Internet and the ease of information access, especially in this “download” culture we live in.
CE Seminar: by Stan Vitton on Thursday, Dec. 9, 2010, from 4-5P in Dow 642. Stan will be talking about:
An Introduction into the RocScience Suite of Software for Use in Civil and Mining Engineering
This year Michigan Tech’s Civil Engineering Department purchased a five year educational license for the The RocScience suite of software. This suite of software includes 12 separate programs for the analysis of rock and soil engineering problems. The programs include stereo net construction, 2 and 3D boundary element programs, 2D finite element that includes slope stability and groundwater seepage analysis, limit equilibrium slope stability analysis, settlement analysis and 3D settlement analysis programs among others. A distinguishing feature of the RocScience suite of programs are their ease of use and their wide application by many civil and mining engineering companies today. The presentation will review each of these programs as well as provide a short introduction on current rock engineering trends, including the Federal Highway Administration (FHWA) use of the the Hoek-Brown failure criteria for dealing with transportation issues in rock.
The CE Seminar this week, Thursday October 21, 4:00PM in Dow 642, will be presented by:
Ted M. Champagne
He will discuss:
Erosion Reduction By Air Entrainment Downstream Of A Stilling Basin
Abstract: Bed scouring at stilling basins downstream of gated spillways has been identified as posing a serious risk to the spillway’s structural stability. Although this type of scour has been studied in the past, it continues to represent a real threat to water control structures and requires additional attention. A 1/30 scale Froudian model of one such structure operated by the South Florida Water Management District was constructed at Michigan Technological University to further study this problem. Gates restricting flow were positioned at the spillway crest and at the end of the flume where the model was built to control the tailwater level. Provisions were made for injecting air into the water as it exited the stilling basing near the endsill. Positioned downstream of the stilling basin was a scour chamber filled with uniformly graded sand representing the channel bed. The “distance check” feature of an Acoustic Doppler Velocimeter was utilized during the experiments to determine when scour equilibrium was established for a particular case. The channel bed contour profile was measured after the scour hole reached equilibrium. Bed scour was studied under various scenarios where numerous water and air flow schemes were considered. These experiments show that utilizing air entrainment can result in scour reduction by up to 58%.
