Jain, A. (author), Marykovskiy, Yuriy (author), Metrikine, A. (author), van Dalen, K.N. (author)Railway transition zones (RTZs) are regions where abrupt track stiffness changes occur that may lead to dynamic amplifications and subsequent track deterioration. The design challenges for these zones arise due to variations in material properties in both the depth (trackbed layers composed of different materials) and longitudinal directions of...journal article 2024

Bedon, Chiara (author), Louter, P.C. (author)Purpose: Glass material is largely used for load-bearing components in buildings. For this reason, standardized calculation methods can be used in support of safe structural design in common loading and boundary conditions. Differing from earlier literature efforts, the present study elaborates on the load-bearing capacity, failure time and...journal article 2023

Murano, Antonio (author), Mehrotra, A.A. (author), Ortega, Javier (author), Rodrigues, Hugo (author), Vasconcelos, Graça (author)This work compares the ability of different numerical modelling approaches to simulate the out-of-plane behaviour of two-leaf stone masonry walls with different masonry bond configurations: an irregular drystone stone masonry wall and a masonry wall with roughly cut regular stone units. Finite element modelling, considering both a micro and...journal article 2023

Singh, Avishreshth (author), Biligiri, Krishna Prapoorna (author), Sampath, Prasanna Venkatesh (author)The use of nondestructive ultrasonic pulse velocity (UPV) testing to assess the hardened properties of pervious concrete (PC) mixtures is an emerging research area. Further, UPV has been successfully used to determine the effective flow resistivity (EFR) of asphalt concrete and cement concrete pavements. However, no research studies have...journal article 2023

Abdul Madhar, S. (author), Mor, A. R. (author), Mraz, Petr (author), Ross, Robert (author)This paper presents the investigation on surface discharge behavior of various dielectric samples under DC. It sequentially develops the knowledge base for the study and analysis of the partial discharge (PD) defect with the goal of PD defect identification under DC. In order to facilitate this, the material properties of the dielectric are...journal article 2021

Alkadri, M.F. (author), De Luca, Francesco (author), Turrin, M. (author), Sariyildiz, I.S. (author)As a passive design strategy, solar envelopes play a significant role in determining building mass based on desirable sun access during a predefined period. Nowadays, advancements in the area of computational tools permit designers to develop new methods for establishing solar envelopes. However, current approaches lack an understanding of the...journal article 2020

Alkadri, M.F. (author), Turrin, M. (author), Sariyildiz, I.S. (author)This paper investigates a prospective application of point cloud data in supporting the contextual analysis of the built environment during the conceptual design process. Often, the complexity of site information causes architects to neglect several relevant properties that may affect environmental performance analysis, especially when dealing...journal article 2019

Lantsoght, E.O.L. (author), van der Veen, C. (author), De Boer, Ane (author), van der Ham, Herbert (author)In 1997, the Second Stichtse Bridge was built in the Netherlands using the balanced cantilever method. The use of high-strength concrete was proposed. At that time, the long-term behaviour of this material was not known, and no code provisions were applicable. Therefore, it was proposed to monitor the material behaviour and the deflections of...journal article 2018

Ekelund, S (author), van Duin, P (author), Jorissen, A (author), Ankersmit, B (author), Groves, R.M. (author)Museum objects are often highly complex and composed of materials with varying properties, some of which may have changed as a result of ageing and/or conservation treatments. Research into defining sustainable environmental conditions by balancing energy cost and risk to these vulnerable objects has mainly focused on experiments in...journal article 2018

Jafari, S. (author), Rots, J.G. (author), Esposito, R. (author), Messali, F. (author)In the northern part of the Netherlands, The recent seismic activities have raised concerns about the behavior of unreinforced masonry structures which were not designed and constructed to resist seismic loading. The first step towards assessment of seismic behavior of masonry structures is to characterize the material properties. This...journal article 2017

Herder, J.L. (author), Cool, J.C. (author), Plettenburg, D.H. (author)For cosmetic reasons, hand prostheses are provided with cosmetic gloves. Their pleasing appearance, however, is accompanied by poor mechanical behavior, resulting in a negative influence on prosthesis operation. Glove stiffness is high and nonlinear, and internal friction in the glove material causes energy dissipation (hysteresis). In this...journal article 1998
