Zhang, F. (author), Yang, Y. (author), Hendriks, M.A.N. (author)To assess the structural capacity of reinforced concrete structures, identifying the internal cracks is important. Acoustic emission (AE) is promising to estimate the location of internal cracks. However, the localization is influenced by many factors like arrival time picking error, presence of crack, etc., resulting in localization error. The...journal article 2023

Zhang, F. (author)Existing concrete bridges require efficient assessment due to increasing traffic load and degrading material. For reinforced concrete structures without shear reinforcement, a typical failure mode is shear, which often means a total loss of structural capacity and does not have an obvious warning beforehand. To indicate the shear failure before...doctoral thesis 2022

Zhang, F. (author), Yang, Y. (author), Fennis, Sonja A.A.M. (author), Hendriks, M.A.N. (author)Acoustic emission (AE) signal parameters can be used to classify the source type in concrete structures. However, signal parameters are influenced by the wave propagation from the source to the receiver, leading to wrong source classification results, especially for monitoring large concrete structures. This paper experimentally evaluates the...journal article 2022

Zhang, F. (author), Yang, Y. (author), Naaktgeboren, N.M. (author), Hendriks, M.A.N. (author)This paper proposes a new damage identification method, namely, the probability density field of acoustic emission (AE) events. This new method provides a different perspective to deal with the uncertainties in the source localization process. We treat the source location as a random variable, and estimate its probability density field based...journal article 2022

Xia, Yi (author), Langelaar, M. (author), Hendriks, M.A.N. (author)Strut-and-Tie modelling (STM) has been widely applied to design D-regions of reinforced concrete structures. For economic and environmental reasons there is a need for optimized Strut-and-Tie models. How to optimize Strut-and-Tie models considering multiple load combinations has not been investigated extensively in the literature. In order to...journal article 2022

Bastidas-Arteaga, E. (author), Rianna, G. (author), Gervasio, H. (author), Nogal Macho, M. (author)The built environment is already facing severe consequences related to climate change. Considering the durability of structures, the increase of carbon-dioxide (CO<sub>2</sub>) concentration and changes on temperature and relative humidity may accelerate carbonation-induced corrosion, thus affecting the service life of reinforced concrete...journal article 2022

Shah, Anjali (author)Global climate change has been a huge matter of concern today. While there are several factors that contribute to greenhouse gases, adversely affecting the planet, CO2 emission is one of them. It is said that 8% of total carbon dioxide emission is caused due to the production of Ordinary portland cement used for concrete in...master thesis 2021

Jilissen, Danny (author)Much of the Dutch infrastructure was built in the 1960s and 1970s and includes an estimated 55.000 bridges and viaducts. These aging structures have reached the end of their designed service life or will reach it in the short term. It is estimated that 15% of these structures have a box-shaped cross-section as being reinforced concrete...master thesis 2021

Geiker, M. R. (author), Hendriks, M.A.N. (author), Elsener, B. (author)In Europe, design for the durability of new reinforced concrete structures is currently based on a prescriptive approach. The design, execution (construction) and planned maintenance of a concrete structure have to lead to the intended level of safety and serviceability throughout its entire service life. This requires numeric models based on...journal article 2021

Engen, Morten (author), Hendriks, M.A.N. (author), Monti, Giorgio (author), Allaix, Diego L. (author)When non-linear finite element analyses are used in design of new or assessment of existing concrete structures, one should account for the modelling uncertainty before conclusions are drawn based on the results. The present article describes the basis for how this topic is treated in the draft of fib Model Code 2020. There are two components...journal article 2021

Jansen, Koen (author)Concrete is one of the most widely applied construction materials worldwide. Although traditional construction processes are optimized in terms of efficiency, costs and material use, the main disadvantages are still related to the use of formwork, labour and limited freedom of shapes in architectural design. The future of concrete structures...master thesis 2020
