de Sousa, Alex Micael Dantas (author), Lantsoght, E.O.L. (author), Debs, Mounir Khalil El (author)Reinforced concrete one-way slabs under concentrated loads can develop different shear failure mechanisms: as wide beams in one-way shear, punching shear around the load or a mixed mode between them. Until now, most publications presented recommendations to assess the shear capacity considering only the one-way shear failure mechanism. This...journal article 2023

Lantsoght, E.O.L. (author), Yang, Y. (author), van der Veen, C. (author)Load testing and in some cases failure (or collapse) testing of bridges is a method to learn more about the behaviour of full-scale bridges in site conditions. Since such experiments, especially failure tests, are expensive, an extensive preparation of these tests is important. This paper addresses the question of when a bridge is a good...journal article 2022

Qian, Z. (author), Lantsoght, E.O.L. (author), Lukovic, M. (author)The increasing demand for sustainable development in engineering practice has triggered researchers to explore solutions to reduce the CO2 footprint caused by ordinary Portland cement (OPC) production. Alkali-activated concrete (AAC), made of by-products using alkali activation, is of great potential as a promising alternative to conventional...conference paper 2022

Lantsoght, E.O.L. (author)One of the methods for the assessment of existing bridges is to subject the bridge to a load test. What is still lacking is a reflection of these recent advances in the codes and guidelines used for load testing of bridges. Two approaches are being used to address this lack. The first approach attempts to answer fundamental questions with regard...conference paper 2022

de Vries, R. (author), Lantsoght, E.O.L. (author), Steenbergen, R.D.J.M. (author), Fennis, S.A.A.M. (author)In the assessment of existing infrastructure performing only a desk study is often not sufficient to determine the structural reliability of a bridge or viaduct. For concrete structures gathering field data by performing a proof load test offers detailed information about the structural performance. However, the relation between the magnitude of...conference paper 2022

Andrade Borges, E.A. (author), Lantsoght, E.O.L. (author), Castellanos-Toro, Sebastián (author), Casas, Johannio Marulanda (author)Progressive deterioration is a problem that affects road infrastructure, especially bridges. This requires the development of methods to determine its influence on structural behavior, one of them being load testing. Within load testing, finite element analysis (FEA) models are used as part of the preparation process. This study focused on the...journal article 2022

Lantsoght, E.O.L. (author)The doctoral defense is an important step towards obtaining the doctoral degree, and preparation is necessary. In this work, I explore the relation between the way in which a doctoral candidate prepares for the defense and two important aspects of the defense: the outcome of the defense, and the student perception during and after the defense. I...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

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

Zarate Garnica, G.I. (author), Lantsoght, E.O.L. (author), Yang, Y. (author)Nowadays, with the aging of the bridges and the advancements in technology, load testing has emerged as an effective method to assess existing concrete bridges with missing information, or where analytical methods do not provide an accurate assessment. Two types of load tests are identified: diagnostic load tests and proof load tests. Both...journal article 2022

(author), Goltermann, Per (author), Schmidt, Jacob Wittrup (author)Advanced monitoring methods are required to identify stop criteria in proof-load tests. In this study, the combined methodology of two-dimensional digital image correlation and acoustic emission is investigated for its applicability for future implementation in field tests. The two monitoring systems are deemed to provide valuable insight...journal article 2022

Mustafa, S. (author), Lantsoght, E.O.L. (author), Yang, Y. (author), Sliedrecht, Henk (author)The safety of existing slab-between-girder bridges is subject to discussion in the Netherlands. Current design codes are conservative for shear-critical girders, and nonlinear finite element analysis is considered a more accurate assessment method. This paper investigates if the Dutch guidelines for nonlinear finite element analysis, which were...journal article 2022

Lantsoght, E.O.L. (author)The doctoral defence is the oral examination of the doctoral thesis. While it is a major milestone for doctoral candidates, this event is often shrouded in mystery. In this article, I explore the doctoral defence from an international perspective.

(author), Sliedrecht, Henk (author)For the assessment of existing slab-between-girder bridges, the shear capacity and failure mode are under discussion. Previous research showed that the static and fatigue punching capacity of the slabs is sufficient as a result of compressive membrane action. The girders then become the critical elements. This research studies the shear capacity...journal article 2021
