Reitsema, A.D. (author), Lukovic, M. (author), Grunewald, S. (author), Hordijk, D.A. (author)Most of the bridges and viaducts in the Netherlands were built in the sixties and seventies of the last century, and an increasing number of them will have to be replaced due to technical or functional reasons. The Netherlands is not an exception, many industrialized countries will face a similar replacement task in the near future. With the...journal article 2020

Lantsoght, E.O.L. (author), Hordijk, D.A. (author), Koekkoek, R.T. (author), van der Veen, C. (author)This chapter describes the proof load testing of viaduct Zijlweg at a position that is critical for bending moment and at a position that is critical for shear. The viaduct Zijlweg has cracking caused by alkali-silica reaction, and the effect of material degradation on the capacity is uncertain. Therefore, the assessment of this viaduct was...book chapter 2019

Lantsoght, E.O.L. (author), Yang, Y. (author), van der Veen, C. (author), Hordijk, D.A. (author), de Boer, A (author)Existing bridges with large uncertainties can be assessed with a proof load test. In a proof load test, a load representative of the factored live load is applied to the bridge at the critical position. If the bridge can carry this load without distress, the proof load test shows experimentally that the bridge fulfills the requirements of the...journal article 2019

Lukovic, M. (author), Hordijk, D.A. (author), Huang, Z. (author), Schlangen, E. (author)Strain Hardening Cementitious Composite (SHCC) is an innovative material which, due to the special material composition and the addition of fibres, exhibits a controlled microcracking behaviour under tensile stresses. As such it might be a promising material for improvement of durability of concrete structures.<br/><br/>An experimental study was...journal article 2019

Lantsoght, E.O.L. (author), De Boer, Ane (author), van der Veen, C. (author), Hordijk, D.A. (author)Proof load testing of existing reinforced concrete bridges is becoming increasingly important as the current bridge stock is aging. In a proof load test, a load that corresponds to the factored live load is applied to a bridge structure, to directly demonstrate that a bridge fulfills the code requirements. To optimize the procedures used in...journal article 2019

Prinsse, S. (author), Hordijk, D.A. (author), Ye, G. (author), Lagendijk, P. (author), Lukovic, M. (author)This paper presents an experimental study on the development of material properties over time (up to around 2 years) and the structural behavior of reinforced beams, for two types of alkali-activated concrete (AAC). Compressive strength, flexural strength, tensile splitting strength, elastic modulus, and flexural behavior of reinforced beams...journal article 2019

(author), Wijte, Simon (author)The sustainability of infrastructure projects is becoming increasingly important issue in engineering practice. This means that in the future the construction materials will be selected on the basis of the contribution they can make to reach sustainability requirements. Geopolymers are materials based on by-products from industries. By using...journal article 2019

(author)This paper presents a development of a ductile alkali-activated fly ash (FA) and ground granulated blast furnace slag (GBFS) based composite as an environmentally friendly material for structural concrete application. For this purpose, polyvinyl alcohol (PVA) fibres and sand aggregate were combined with alkali-activated paste. Workability,...journal article 2018

Ensink, S.W.H. (author), van der Veen, C. (author), Hordijk, D.A. (author), Lantsoght, E.O.L. (author), van der Ham, Herbert (author), de Boer, A. (author)In the Netherlands, approximately 150 prestressed T-beam bridges with cast-in-between decks and mainly built in the sixties are still in service. Upon assessment, the prestressed beams often do not fulfil the design codes requirements, whereas upon inspection, they show no signs of distress. For the assessment, additional load transfer...conference paper 2018

Zivkovic, Jelena (author), Lukovic, M. (author), Øverli, Jan Arve (author), Hordijk, D.A. (author)Modern society and infrastructure are facing an increased demand for fast construction. A number of viaducts are aged and will need to be replaced in near future. When considering this replacement task, lightweight, slender bridge is the solution. Dead load reduction and high-strength to weight ratio are the main advantages when using the...conference paper 2018

Lukovic, M. (author), Yang, Y. (author), Schlangen, E. (author), Hordijk, D.A. (author)Different analytical models exist to predict the shear strength of reinforced concrete members. Generally, each of these shear strength models consists of a formulation based on certain underlying theory and fitted model coefficients. The model fitting parameters are usually established from the comparison with test data. Hence, the predictive...conference paper 2018

Lantsoght, E.O.L. (author), Yang, Y. (author), van der Veen, C. (author), Hordijk, D.A. (author), De Boer, Ane (author)As the existing bridge stock is aging, improved assessment methods such as proof load testing become increasingly important. Proof load testing involves large loads, and as such the risk for the structure and personnel can be significant. To capture the structural response, extensive measurements are applied to proof load tests. Stop criteria,...conference paper 2018

Lantsoght, E.O.L. (author), Koekkoek, R.T. (author), Hordijk, D.A. (author), de Boer, A. (author)Proof load tests of bridges can be very useful for structures with a lack of information, or for structures of which the effect of material degradation is difficult to assess. Contrary to diagnostic load testing, proof load testing is not well-defined in current standards in terms of required load and analysis of measurements. The risk...journal article 2017

Lantsoght, E.O.L. (author), Yang, Y. (author), van der Veen, C. (author), de Boer, A. (author), Hordijk, D.A. (author)Loading protocols and acceptance criteria are available in the literature for load tests on buildings. For bridges, proof load tests are interesting when crucial information about the structure is missing, or when the uncertainties about the structural response are large. The acceptance criteria can then be applied to evaluate if further loading...journal article 2017

Lantsoght, E.O.L. (author), van der Veen, C. (author), de Boer, A. (author), Hordijk, D.A. (author)Proof load testing is part of the engineering practice, and can be particularly useful for the rating of existing bridges. This paper addresses how reliability-based concepts can be used in combination with proof load testing, and discusses how this approach differs from the current practice for proof load testing. Whereas the calculation...journal article 2017

Lantsoght, E.O.L. (author), van der Veen, C. (author), de Boer, A. (author), Hordijk, D.A. (author)Load testing of bridges is a practice that is as old as their construction. In the past, load testing gave the traveling public a feeling that a newly opened bridge is safe. Nowadays, the bridge stock in many countries is aging, and load testing is used for the assessment of existing bridges. This paper aims at giving an overview of the current...journal article 2017

This paper addresses the preparation, execution, and analysis of a proof load test on a four-span reinforced concrete solid slab bridge, viaduct de Beek. The bridge has one lane in each direction, but was restricted to a...conference paper 2017
