Kisoensingh, Arvind (author)Flexural shear failure is a brittle failure mode that can occur in reinforced concrete (RC) beams without stirrups due to the combination of flexural and shear stresses. The failure mode begins with vertical flexural cracks at the bottom of the RC beam central span area due to flexural tensile stresses, followed by diagonal cracks. During...master thesis 2023

Streng, Robin (author)Nowadays, Rijkswaterstaat reassesses many older concrete bridges to guarantee their structural safety under the influence of increased traffic loads and stricter standards. Many of these concrete bridges contain open straight-legged stirrups, which are not allowed to take into account for the calculations of the shear resistance according to...master thesis 2023

de Sousa, Alex M.D. (author), Lantsoght, E.O.L. (author), El Debs, Mounir K. (author)One-way slabs under concentrated loads may fail by one-way shear, two-way shear, flexure, or a combination of these modes. This paper reviews shear and punching shear-failure mechanisms of one-way slabs under concentrated loads tested from the literature and investigates the accuracy of different approaches to predict the ultimate capacity...journal article 2023

Tai, Ricky K. (author), Slobbe, Arthur T. (author), Roosen, M.A. (author)For structures whose structural safety cannot be demonstrated using the applicable code regulations, a nonlinear finite element analysis (NLFEA) can be used to investigate the structural behavior and maximum load capacity. The Dutch Ministry of Infrastructure and Water Management uses a dedicated guideline for NLFEA in such an assessment....conference paper 2023

Sierra, P.L. (author), Poliotti, M. (author), Yang, Y. (author), Martinez García, Xavier (author), Chacón, Rolando (author)In this work, dynamic characterization of a simply supported beam is carried out during different steps in a failure load test. The main goal of this work is to evaluate the evolution of the structural dynamic parameters of the beam with different status of damage. Real-scale prestressed concrete beams are tested to investigate its shear...conference paper 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

Vallejos Balladares, Andres (author)To calculate the flexural-shear resistance of prestressed concrete members without shear reinforcement, a method based on Critical Shear Crack Theory (CSCT) has been presented for the new Eurocode (prEN1992). Two alternatives provided in draft 7/2020 (prEN1, prEN2) are the starting point given, and two other alternatives are proposed for...master thesis 2022

Sousamli, M. (author), Messali, F. (author), Rots, J.G. (author)Plane-stress and shell macromodels are often preferred to analyze masonry structures because of their numerical efficiency. However, they often misestimate the hysteretic behavior of the structures. Additionally, due to the nature of smeared cracks, the cracks may be diffused. This article proposes a new orthotropic model, which focuses on...journal article 2022

Roosen, M.A. (author), Yang, Y. (author), van der Veen, C. (author), Schaafsma, Dick G. (author), Hendriks, M.A.N. (author)When the shear resistance of prestressed beams with stirrups is determined with the current Eurocode, no distinction is made between regions with and without flexural cracks. This while it may be expected that a region without flexural cracks will have a higher shear resistance. This is due to the lower longitudinal strains and the narrow...journal article 2022

Fusco, Daniela (author), Addessi, D. (author), Messali, F. (author), Rots, J.G. (author), Pampanin, S. (author)Since the 1980s, calcium silicate element masonry has been commonly used in Dutch buildings, and vertical continuous joints have been usually located at the corner of perpendicular walls. Since the shear failure of these joints may significantly reduce the seismic performance of the flanged wall and therefore of the entire building, the...journal article 2022

Roosen, M.A. (author)In the design process of prestressed bridges and viaducts, the required amount of shear reinforcement is determined with a model that assumes the presence of flexural cracks. In order to keep the design process simple, this model is also prescribed to determine the amount of shear reinforcement for the regions of the structure in which, at the...doctoral thesis 2021

Yang, Y. (author), de Boer, Ane (author), den Uijl, J.A. (author)A recent contest of shear tests modelling was carried out in 2019. Teams from universities and consultancies around Europe were invited to predict the shear capacity of two reinforced concrete beams. The basics of the numerical models were to be set up according the Dutch NLFEM Guideline RTD 1016–1:2017. In the contest, two reinforced...journal article 2021

van Damme, M. (author)When soil surfaces are exposed to high shear stresses induced by high-velocity water flows, they erode. Erosion consists of the detachment, entrainment and transport of soil particles. When exposed to high shear stresses the process of soil detachment is no longer given by the pick-up of individual particles but by the continuous shear failure...journal article 2020

Vergeer, Marieke (author)Old bridges in the Netherlands are reassessed to prove their structural safety because of the increased traffic loads. The Eurocode model for the shear capacity of prestressed concrete beams with sufficient shear reinforcement was found to be very conservative for small amounts of transverse reinforcement, which is typical for old bridges. Code...master thesis 2019

Zarate Garnica, Gabriela (author)Shear failure is one of the most critical failure modes of reinforced concrete members, especially for those without shear reinforcement. Despite the extensive research programs in the last decades, there is still no general agreement on a rational theory to assess their shear capacity. In the recent years, researchers have focused on developing...master thesis 2018

Jayananda, Nikhil (author)The growing need for strengthening of concrete structures to improve their structural performance challenges structural engineers to come up with strengthening techniques that is most suitable and effective for a structural system in its deteriorated state. Although there are quite a few techniques in practice for strengthening of concrete...master thesis 2018

Sudhakaran, Kamaleshwar (author)Failure of slopes has been a frequently occurring hazard, which leads to loss of life and resources. To stabilize the slopes, vegetation has been used, where stump of plant roots act as passive piles by providing mechanical reinforcement. In this research, effect of spacing of trees on load transfer mechanism in a slope has been studied and...student report 2018

Snijders, A.M.M. (author)Within this document the differences arising from the transition of the NEN (Dutch code) to the Eurocode are studied with respect to shear failure and fatigue. These differences are investigated on a global level, where in addition the fib Model Code is taken into account. In the next part the actual differences are determined within a case...master thesis 2013

van der Put, T.A.C.M. (author), van de Kuilen, J.W.G. (author)The elastic—full plastic loading curve is for all materials sufficient to explain the strength of beams and beam columns loaded by bending and compression. This theory is extended for the influence of shear stress, and it is shown to be the only way to explain the combined bending-shear strength from test results. Also, the in the past derived...journal article 2011
