Sewcharan, Ashish (author)Port of Rotterdam has the ambition to reduce the footprint for building new quay walls, this is in line with their ambition to reduce the footprint and with national goals to limit global warming. The aim is to use less materials and/or use different design solutions. These reinforced structures are designed in a conventional way and the...master thesis 2023

Tawfek, Abdullah M. (author), Ge, Zhi (author), Yuan, Huaqiang (author), Zhang, Ning (author), Zhang, Hongzhi (author), Ling, Yifeng (author), Guan, Yanhua (author), Šavija, B. (author)The mechanical performance of engineered cementitious composite (ECC) depends greatly on fiber orientation and distribution. In this paper, the effect of fiber orientation on ECC's mechanical properties was investigated using two different casting methods: a flow-induced casting was used to enhance the fiber orientation within ECC mixture and...journal article 2023

Bezemer, Jelle (author)Limiting maximum crack widths is a serviceability limit state, which ensures the durability of reinforced structures. In current practice, maximum crack widths are limited by using additional reinforcement, on top of the amount of reinforcement required for the designed ultimate bearing capacity. Reducing the amount of reinforcing steel used,...master thesis 2022

Yilmaz, Fidel (author)When concrete is subjected to imposed deformations, stresses may develop. If at any point in time this stress exceeds the tensile strength of the material, the concrete will crack. Early-age cracking of concrete structures may lead to problems with durability, serviceability and aesthetics. During hardening of concrete the material properties...master thesis 2022

Moharekpour, Milad (author), Liu, Pengfei (author), Schmidt, Joshua (author), Oeser, Markus (author), Jing, R. (author)The Guide for Design of Pavement Structures (AASHTO 86/93) and Mechanistic Empirical Pavement Design Guide (MEPDG) are two common methods to design continuously reinforced concrete pavement (CRCP) published by the American Association of State Highway and Transportation Officials (AASHTO) in the USA. The AASHTO 86/93 is based on empirical...journal article 2022

Pradena, Mauricio (author), Houben, L.J.M. (author), César, Andrés (author)Generally, joint performance in concrete pavements is evaluated in laboratory by applying dynamic loads that require large scale experimental setups. In order to propose a simplified laboratory test, a comprehensive literary review of the fundamentals of load transfer at joints is made, and the load transfer efficiency obtained via a reduced...journal article 2022

Sun, Renjuan (author), Lu, Wei (author), Tawfek, Abdullah M. (author), Guan, Yanhua (author), Hu, Xinlei (author), Zhang, Hongzhi (author), Ling, Yifeng (author), Šavija, B. (author)The resistance of cracked ECC against chloride ingress is mainly governed by the accumulated crack width of all the cracks rather than the maximum width of multiple cracks. However, most studies focus on the influence of a single fine crackjournal article 2022

Zondag, Youri (author)Since 2006, the Delft University of Technology has been working on the development of bacterial self-healing concrete (BSHC). The self-healing ability of this concrete is based on a biological mechanism, in which mineral producing bacteria are added to repair cracks autonomously. This not only improves the durability of concrete structures, but...master thesis 2021

Tan, Reignard (author), Hendriks, M.A.N. (author), Geiker, Mette (author), Kanstad, Terje (author)This paper formulates an analytical calculation model for predicting the cracking behavior of reinforced concrete ties to provide more consistent crack width calculation methods for large-scale concrete structures in which large bar diameters and covers are used. The calculation model was derived based on the physical behavior of reinforced...journal article 2020

Pradena, M.A. (author), Houben, L.J.M. (author), César, Andrés (author)Aggregate interlock is the dominant load transfer mechanism in non-dowelled Jointed Plain Concrete Pavements, as the innovative short concrete slabs. Although the Load Transfer Efficiency of this pavement innovation is based on that mechanism, the structural design methods do not relate the Load Transfer Efficiency by aggregate interlock with...journal article 2020

Tiwari, Anshuman (author)Shear cracking in slender reinforced concrete beams with thin webs can result in significant shear crack width and deflection which is usually ignored in practice due to lack of availability of the engineering models in design codes. This can lead to unconservative predictions of the crack width and total deflection in the SLS (Serviceability...master thesis 2019

Odijk, Maik (author)This research focuses on the structural behaviour of an elastic supported reinforced concrete slab. Over the years, there is a tendency to realise industrial floors with large joint-spacings. The downside of a slab on grade with a large joint-spacing is that the risk of (uncontrolled) cracking due to a shrinkage load is higher, which often...master thesis 2019

Meek, Maarten (author)To realise more sustainable industrial ground floors the implementation of alkali-activated concrete is considered for jointless elastically supported ground floors. Such floors are realised with large areas without dilations, the shrinkage reduction is therefore restrained causing cracks to arise at the top surface of the floor. The control of...master thesis 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

Palin, D. (author), Mo, Yu (author), Wiktor, V.A.C. (author), Jonkers, H.M. (author)Presented is a modified test for generating crack permeability data for cementitious materials. Single-parallel cracks were generated in mortar specimens. The width of the cracks was analysed through stereomicroscope and computer tomography, and the water permeability of the cracks was determined. Reduction factors and crack flow models were...journal article 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

Tan, Reignard (author), Hendriks, M.A.N. (author), Geiker, M. (author), Kanstad, T. (author)The modified cracked membrane model (MCMM) presented in this paper was formulated to facilitate a mechanical calculation model that predicts crack widths in reinforced concrete (RC) structures subjected to in-plane loading for all cracking stages. It was formulated using the basic concepts of the existing cracked membrane model (CMM)....journal article 2019

Verschuur, Richard (author)This Master Thesis is about the comparison of the effective concrete tension zone height determined with either finite element models using DIANA or Eurocode 2 and Jones method. The effective reinforcement ratio is an important parameter for the determination of the crack width and is depending on the effective concrete tension zone height....master thesis 2018

Knuvers, Peter Bart (author)When engineers at Tunnel Engineering Consultants (TEC) used the Eurocode 2 (EC2) for the verification of flexural cracks in cross sections of immersed tunnel elements, they found out that there was more reinforcement needed for crack width limitation than for tensile strength of the reinforced concrete. This raised questions, namely whether the...master thesis 2018
