1st INFRASTAR Spring School in Ifsttar, Nantes

Image
Last week, I spent a wonderful time in Ifsttar, Nantes. And attended the 1st INFRASTAR spring school.
Students and experts from different universities and companies came to this event.  During this week, we have learnt a lot, not only from the lectures by the professors, but also we gained a lot of experience explaining our research and 'guiding' the others to do the exercises that we prepared. (doing exercises) (Explaining my research) (dinner together)
We spent a great time together, everything is just to the point! This is the charm of our project, of Marie Skłodowska-Curie Actions, rich and colorful.

Are you interested in the next training school? Please follow INFRASTAR.

Secondment in BASt, Bergisch Gladbach Part 1

Image
I just came back to BAM from a 3 weeks business trip. Tired, but meaningful. 
I spent two weeks in BASt (federal highway research institute) to do my secondment. The idea was to install the ultrasonic sensors that I use on a real bridge (druaBast). (strong Marco on the left and Tall Heiko on the right)
I worked together with my colleagues from BAM, Marco and Heiko. I am so grateful for their professional and  precise work. I am very luck and happy to have the chance to installed our embedded sensors and implement our method on a real bridge. 
Now, let's start the work!  (measuring the distance to determine the position of sensors) (Checking rebars by GPR device) Drilling holes on the bridge. (installing sensors......) This is how it looks in the end, beautiful, isn't it? All the cables were protected well in the PVC tubes. 
After a few days hard work with my Germany colleagues, of course beer is necessary. Prost
For more details about how to install the sensors, pls follow our p…

Implementation of CWI on real bridge!!!

What is the goal of science?
Why we do scientific research?
The final goal is to apply science in our real life!!
For some people, PhD students are
I would say, correct! We are like this! We need to read a lot of articles, we need to do test in the lab, we need to analyze our data on PC.
BUT! As a civil engineer, we are also like this: In September and October 2018, I did my secondment in Neostrain, KRAKOW, in Poland.
I was lucky to have a chance to implement CWI method on a real bridge (Gliwice bridge).
Embedded ultrasonic sensors were installed inside the bridge girder. Measurement devices were locked in this big box under the bridge.
Me and ESR3 Joyraj did the test together. We monitored the bridge girder for 5 days to study the influence of real traffic and temperature. 
Now we have some interesting result and  we are planning to publish papers based on this test.

Zhuhai-Hong Kong-Macao Bridge is opened now

Zhuhai-Hong Kong-Macao Bridge is opened now
Hi everyone, today I will introduce a Mega project which must be very interesting for all ESRs of INFRASTAR project.
This week, the world's longest bridge 'Hong Kong-Zhuhai-Macao Bridge' is opened officially. This bridge will connect three chinese cities: ZhuHai (in GuangDong province), Macau and Hong Kong. 4 hours drive will be shortened to half an hour.

The 'sea-based' project bridge is about 55 km long. There are 3 main 'towers'
The 'sail tower' meaning 'bon boyage' The 'Dolphin Towers' symbolizing ecological harmony. The 'Chinese Knots' celebrating connection of the three cities.  Two artificial islands link sections of the bridge with a 6.7 km undersea tunnel. The components of the bridge were pre-fabricated on production lines, shipped to the sea and assembled on site  33 tunnel elements were precast in 53 months without a single cracks. This is a really young bridge. I have …

My road taken during the first year.

Happy new year everyone! I have learned a lot during my first year. I participated some workshops and trainings. I worked together with Antoine(ESR2), Joyraj(ESR3) and Imane(ESR4). Team work is really important. In 2018, I will focus on writing some papers and participate some conferences. Bye 2017

INFRASTAR Second Training Week at EPFL in Lausanne Switzerland

Image
INFRASTAR Training Week #2 In November, we went to EPFL (école polytechnique fédérale de Lausanne) for our second training week of INFRASTAR project. During this training week, we presented our previous result and progress but we focus on discussing our future plan: what we will do during the following years, how we cooperate with other ESRs.
Welcome to the training week
#DAY 1# Group Discussion  Visit bridge made with UHPFRC #DAY 2#
#DAY 3#
My presentation


 #DAY 4#
MR Ernst Niederleithinger gave us a course about signal analysing.
Mr Marek Salamak gave us one of the most interesting lecture.
then we eat fondue together.

 #DAY 5#
What 'spirit' should we have for team working and project management.
We spent a great time together, I am so happy to meet all the ESRs again. And I learned a lot during the second training week. I can't wait for the next training week. Thanks to Mr Eugen Brühwiler for organising this event. See you next year.




TEAM-TAG (Team day) with my colleague.

Image
This month, I went to the zoo with my colleagues during the team day.
I really enjoy my work in BAM. I like the working environment. My colleagues are so nice. My boss is so nice. It is not only my 'work' but also my 'life'. And I also have some new result, I compared it with Ernst(my supervisor)'s result. Now I am waiting for Joy(ESR3)'s new filter.
