van Starrenburg, Pim (author)In the construction of subsoil structures, a common challenge is the presence of a high groundwater level in combination with the absence of a naturally impermeable layer or an environment susceptible to settlements due to lowering the groundwater level. To overcome this issue, a building pit with an underwater concrete floor (UCF) can be...master thesis 2023

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

(author)This article presents a numerical study on the influence of the anchorage shear hysteresis on the seismic response of nonstructural components (NSC) connected to multi-storey reinforced concrete (RC) buildings, and of the anchorage itself. To cover a variety of different types of shear hysteresis shapes, this contribution considered the...journal article 2023

Slegers, Ron (author)An experimental research into the use of basalt as reinforcement in concrete to reduce the ECI value of a concrete quay wall apron. In this research experiments with basalt minibars and basalt reinforced polymer rebars are performed to compare directly to steel fibres and steel rebars. With the test results 4 designs are produced resulting in...master thesis 2022

Hamelers, Arthur (author)Villa Henny (1916), designed by Robert van’t Hoff, baptized as the concrete villa, defines a turning point in modernism in the Netherlands. The Villa has been extensively researched in relation to the De Stijl art movement and influence by the American architect Frank Lloyd Wright, yet less attention has been given to the fact that it is one of...student report 2022

de Putter, Arjen (author), Hendriks, M.A.N. (author), Rots, J.G. (author), Yang, Y. (author), Engen, Morten (author), van den Bos, Ab A. (author)Nineteen 2D nonlinear finite element analysis (NLFEA) solution strategies were benchmarked against a wide variety of 101 experiments on reinforced concrete beams failing in bending, flexural shear, or shear compression. The relatively high number of solution strategies was motivated by the conviction that choices for the constitutive models,...journal article 2022

Vargas, Daniel (author), Lantsoght, E.O.L. (author), Genikomsou, Aikaterini S. (author)Eccentric punching shear can occur in concrete slab–column connections when the connection is subjected to shear and unbalanced moments. Unbalanced moments occur in all floor slabs at the edge and corner columns. As such, this problem is of practical relevance. However, most punching experiments in the literature deal with concentric punching...journal article 2022

Slobbe, Arthur (author), Rózsás, Árpád (author), Yang, Y. (author)This paper presents a reliability-based calibration method for design code formulas. The method is demonstrated on the shear design formulas in Eurocode 2 and fib Model Code 2010 (MC2010). We found that the partial factor (Formula presented.) in the current Eurocode 2 is about 20% lower than the optimal value and, thus, provides an...journal article 2022

Carrera, Bernardo (author), Lantsoght, E.O.L. (author), Alexander, Scott D.B. (author)The strip model describes a load path prior to failure that can be tailored to a wide range of slabs under concentrated loads, both concentric and eccentric. Eccentric punching shear can occur in concrete slab-column connections subjected to shear and unbalanced moment, such as edge and corner columns. This paper shows how the strip model is...conference paper 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

Kongshaug, Simen Sørgaard (author), Hendriks, M.A.N. (author), Kanstad, Terje (author), Markeset, Gro (author)Alkali–silica reaction (ASR) in concrete causes expansion and degradation of the material, which might give adverse structural consequences. From the structural engineer point view, the greatest concern is if ASR leads to loss of structural integrity. Two natural questions arise when assessing existing concrete structures affected by ASR: (1)...journal article 2022

Tavera Diaz, Daniela (author)Nowadays, one of the main requirements from civil engineering structures is the level of reliability and safety that they must provide to the users. In structural analysis, the exponential application of numerical methods, as the nonlinear finite element analysis (NLFEA), is due to the increasing growth of computational power. These powerful...master thesis 2021

Zhang, Zhidong (author), Angst, Ueli M. (author)The structure of concrete, in particular the microstructure of the steel-concrete interface (SCI), can significantly affect corrosion of rebars. To support corrosion, oxygen needs to diffuse from the ambient environment to the steel surface. Meanwhile, corrosion products transport through the SCI and precipitate in concrete. Transport properties...conference paper 2021
