Anish PushpangadanAnish Kayiparambil P

Anish KP is a M.S student in Structural Engineering at Civil and Environmental Engineering Department at Tufts University. He received his B.Tech in Civil Engineering from National Institute of Technology Calicut, India in 2006. After graduation he worked with Alstom Projects India Ltd. for five years as a lead engineer and was responsible for review of civil design and construction drawings for various structures in Thermal power projects and providing technical support to civil construction team located in Oman and Saudi Arabia.

Anish is currently working with Professor Sanayei on the study of train-induced floor vibrations. The design of buildings for human comfort and specialized purposes such as manufacturing or operation of sensitive equipment calls for prior knowledge of ambient floor vibrations envisaged in the building. The ability to predict and quantify these vibration levels enables engineers to incorporate sufficient mitigation measures in the building design. Anish will be working on vibration prediction, propagation and mitigation methodologies in a building.

During leisure Anish likes to travel and explore new places & cuisine.


Jesse Sipple Jesse Sipple

Jesse Sipple, EIT is a Ph.D. Candidate studying Structural Engineering and Mechanics in the Civil and Environmental Engineering Department at Tufts University. His advisor is Dr. Masoud Sanayei. Jesse is part of the National Science Foundation Partnership for Innovation "Whatever Happened to Long-Term Bridge Design" research team, focusing on the use of frequency response functions (FRFs) for model calibration of full scale bridge finite element models in conjunction with experimental FRF data. Jesse received both his B.S. and M.S. in Civil Engineering from the University of New Hampshire (UNH) in 2007 and 2008 respectively.

Jesse has been working with the Powder Mill Pond Bridge (Vernon Avenue Bridge) from the start, helping implement a successful instrumentation plan during the construction phase of the project. Since the opening of the bridge in September 2009, Jesse has taken the lead in planning and performing three load tests on the bridge with a team of researchers from Tufts, UNH, FST Inc., and Geocomp Corp. The first load test in September 2009 was a static load test with a fully load dump truck performing both rolling and stop locations tests. The second load test performed in July 2010 had the previous static component and a new vibration component using a shaker to dynamically excite the bridge and accelerometers to measure the response. The third test performed in September 2011 was very similar to the second load test. His research has been focused on using dynamic based frequency response functions to calibrate full scale finite element models. Jesse is currently working on developing a program to perform this model calibration. He is preparing to use that program on several different structures, including the Powder Mill Pond Bridge, to investigate the usefulness and effectiveness of his proposed methods. Jesse will also synthesize the information from entire NSF-PFI research project into recommendations for including bridge modeling and testing into bridge management programs.

Peeyush RohelaPeeyush Rohela, MS '12

Peeyush is currently a graduate student pursuing M.S. in Structural Engineering from Tufts University. He is working with his advisor, Prof. Masoud Sanayei, on the development of a MATLAB® based program called PARIS© 13.0 for Automated Finite Element Model (FEM) Updating of full scale structural models. The parameter estimation techniques are based on minimization of static and modal error functions previously developed at Tufts University. The program is designed to use both analytical and numerical sensitivities for optimization. A unique feature of this program is that it employs SAP2000® for finite element analysis during the analysis stage of FEM updating process through the use API (Application Programming Interface). Not only does this provides the user with SAP2000® GUI but also allows for the creation of larger finite element models with more complex geometries. The research is aimed at continued program development and its eventual deployment for calibration of finite element model of the Powder Mill Bridge in Barre, Massachusetts, using static and dynamic Non-Destructive Test (NDT) data.

Prior to his graduate studies, Peeyush worked for two years as a design engineer at Fluor Daniel in India. He received his bachelor's degree (B.E.) in Civil Engineering from Birla Institute of Technology, India, in 2008.

Paul RosenstrauchPaul Rosenstrauch, MS '12

Paul received his B.S. in Civil Engineering from Tufts University in 2010. He is now working towards his M.S. in structural engineering. His research, conducted with Professor Brian Brenner, focuses on how changes in temperature affect bridge structural behavior. This is important as the strains caused by daily and seasonal changes in temperature may be as much, if not greater than, those strains caused by live traffic loading. The case study in this research is the Little Mystic Truss span of the Maurice J. Tobin Memorial Bridge, which has been instrumented with a structural health monitoring system. An extensive three-dimensional finite element modeling of the Little Mystic span has been developed. He will be using the strain information from the instrumentation system to update the Little Mystic model and to define the structural response of the Little Mystic Truss to changes in temperature.

Gusset plate performance is an important topic in structural engineering, and so Paul will also be researching the behavior of the gusset plates in the Little Mystic Truss. He will add the gusset plate elements to the Little Mystic Truss model and perform a full finite element analysis of the plates. He will compare the strains predicted by the model to the strains recorded by the instrumentation system during a full scale load test that was conducted in the fall of 2009.

Peter MoserPeter Moser, MS '10

Peter Moser received his B.S. in Chemistry from Wheaton College (IL) in 2003. He is currently pursuing a M.S. in Civil Engineering from Tufts University and he is working with Prof. Moaveni. Peter's research interest is in vibration-based Structural Health Monitoring (SHM). The key component of the research project is a continuous monitoring system deployed on the Dowling Hall Footbridge at Tufts. The system continuously monitors ambient/traffic induced vibrations at eight locations and temperatures at ten locations. A set of programs automatically transfer, process, and analyze each data set. The dynamic characteristics of the bridge can be extracted from each sample.

The dynamic characteristics of the bridge are sensitive to damage but also to temperature. If the system is to be used to accurately detect damage, the effect of environmental conditions must be well understood. Peter's current work includes investigation of the relationship between temperature and the natural frequencies of the bridge, development of a nonlinear model quantifying this relationship, and assessment of the model accuracy.

Eric PheiferEric Pheifer, MS '10

Eric J. Pheifer received his B.S. in Civil Engineering from Tufts University in 2008. He is currently pursuing a M.S. in Civil Engineering from Tufts University and he is working with Prof. Brenner. Eric's Master's thesis focuses on the Tobin Bridge, a 2-1/4 mile long bridge composed of a number of steel approach and truss spans between Boston and Chelsea, MA. Finite element models have been developed for most of the structure. A detailed model was developed for one of the truss spans and a system of instrumentation was installed on the span. Non-destructive testing of the bridge was performed. Collected strain data from the load test is used to update and calibrate the finite element model.

The research project is hosted by Fay, Spofford & Thorndike, LLC in Burlington, MA where Eric is an Assistant Engineer. When not busy working on the Tobin Bridge, Eric works on developing 3-D project visualization for proposals and client meetings. Eric also enjoys scuba diving on the north shore on weekends when the water is not numbingly cold.
