On June 14th, Gabriela Zarate Garnica and Eva Lantsoght of the Concrete Structures research group taught an online webinar on Bridge Load Testing to the University of Costa Rica – Lanamme (National Laboratory of Materials and Structural Models). This invitation came after Eva worked with faculty of UCR – Lanamme on the new Costa Rican Manual for Bridge Evaluation, which includes a chapter on bridge load testing. This chapter is largely based on e-circular 257 “Primer on Bridge Load Testing” of the Transportation Research Board, instead of on the current AASHTO Manual for Bridge Evaluation, which is based on the 1998 Manual or Bridge Rating through Load Testing. The authors of the TRB e-circular are a task force chaired by Eva within TRB Committee AKB 40 “Testing and Evaluation of Transportation Structures”.
In the webinar, Eva focused on the following topics related to bridge load testing: definition of a load test, load test types and classification, feasibility analysis for using load testing, general considerations for bridge load testing, differences between load tests on new and existing bridges, and international experiences. Gabriela presented her research on stop criteria for proof load testing of reinforced concrete slab bridges, based on the experiments that are currently in progress in the Stevin II Laboratory.
Herbert van der Ham started last July as a teacher at the section concrete structures. In the first instance, he will deal with the bachelor courses in reinforced and prestressed concrete and supervising Master graduates. In addition to working at Delft University, he works as an engineer at Boskalis and as a teacher at the 'Betonvereniging'. After graduating from Delft University in 2004, he worked as an engineer and consultant at Iv-Infra and Rijkswaterstaat, interrupted by a PhD research into 'Microstructure and transport phenomena in visco-elastic modeling of hardening cementitious materials.
Shozab Mustafa is starting his PhD in the group of concrete structures under the supervision of Mladena Lukovic in efforts to characterise the concrete-to-concrete interface. The focus of the study is the quantification of the interfacial bond strength and its role in crack-width control of innovative composite structures consisting of Strain Hardening Cementitious Composite (SHCC) and concrete. He chose this topic as his area of focus because it combines both his interests i.e. innovative construction materials and the structural response of composite members. We look forward to working with him!
Dear students and colleagues,
Over the past six years I had the opportunity to be involved in education on concrete structures together with you: it was an honour and it brought me a lot of pleasure. In 1985 I left the faculty of Civil Engineering at TU Delft as a student after acquiring my diploma as engineer and I never thought that I would ever return in a different role. Sometimes strange things happen in life! Thanks to you I had a great time all those years with the participation on the educational trip organised by Practische Studie for me as one of the highlights. As of now I will be focussing again on my role as structural designer at Aronsohn Constructies consulting engineers b.v.. Perhaps that I will meet some of you there or somewhere else in the world of structural engineers. I would love that!
Thanks and looking forward to meeting you,
On the weekend of the 24th of May, the Concrete Canoe Race will take place in 'S-Hertogenbosch. For this year competition, our TU Delft team has been working hard to make a marble-smooth lightweight canoe.
Now it is time to try it out and master their rowing skills (see the video below). Join the Race Weekend and support them winning the trophies!
March 1, Professor Dick Hordijk left the university to focus completely on his company Adviesbureau ir. J.G. Hageman B.V. He has been a valuable person at the university for many years in the group of Concrete Structures and is known by the students from the master course Forensic Structural Engineering and other bachelor courses. Professor Hordijk looks with a great pleasure on his time at TU Delft and appreciates very much his collaboration with students and colleagues. He sends you a following message:
“Dear students and colleagues,
I feel very sorry that I am going to leave you. Combining my job in the office with the one at the university appeared to be too heavy and that is the reason that I decided to stop. The contacts with you I really appreciated very much. I wish you a bright future and all of you success with your study and in your career. And I look forward to meeting several of you in practice in the coming years!
Many thanks and kind regards,
René Braam was elected Lecturer of the Year 2018 of the Concrete Association during the Concrete Day 2018 in the Doelen in Rotterdam.
The Concrete Day is an annual expertise and networking event. This year's theme was: Concrete, more sustainable than ever! Sustainability is a theme that is of vital importance for the entire concrete chain – from exploration of raw materials to the final recycling of concrete.
Mladena Luković is one of seven TU Delft scientists to be awarded a grant by NWO. The three year stipend will enable the concrete structures expert to continue her research and further develop her ideas.
Concrete structures do not meet current societal demands: fast construction, low maintenance and sustainability. Innovative systems are urgently needed. Hybrid concrete structures, combining innovative and conventional concretes, are possibly the future.
Professor Dick Hordijk gave four lectures at the International Summer School Performance, Protection & Strengthening of Structures under Extreme Loading (6th-11th July, 2018) in Lecco, Italy.
Our group and Albert Reitsema as a first author took part at the International Competition: World Innovation in Bridge Engineering (WIBE) Prize.
The winner of the Prize, selected by a qualified Jury, is a “Paper” that demonstrates the greatest potential of innovation and contributes to the development of Bridge Engineering worldwide.
The competition consisted of 74 papers which were submitted by more than 200 authors, from 50 countries all around the world.
We are happy to announce that our paper reached all population levels and finally was ranked 4th at WIBE Prize 2017.
