De Boer, Ane (author), Lantsoght, E.O.L. (author), Yang, Y. (author)The Dutch Ministry of Infrastructure and the Environment is concerned with the safety of exist-ing infrastructure and assessment thereof, which can be done with nonlinear finite element analysis. The 2017 updated version of the Dutch NLFEA Guidelines can be used for reinforced and prestressed beams and slabs. The purpose of the guidelines is...conference paper 2020

Balayn, A.M.A. (author), SOILIS, P. (author), Lofi, C. (author), Yang, J. (author), Bozzon, A. (author)Global interpretability is a vital requirement for image classification applications. Existing interpretability methods mainly explain a model behavior by identifying salient image patches, which require manual efforts from users to make sense of, and also do not typically support model validation with questions that investigate multiple...conference paper 2021

Zhang, F. (author), Yang, Y. (author), Hendriks, M.A.N. (author)Acoustic Emission (AE)-based crack tracking is a promising approach to locate cracks in concrete structures. Different from conventional AE, this approach uses AE activities during crack closure. But, AE activities during crack closure may be influenced by the number of load cycles and loading speed. This may challenge the applicability of AE...conference paper 2021

(author)Proof load testing can be an interesting method to assess existing bridges for which analytical methods are unable to provide an accurate assessment. In a proof load test, a load representative of the factored live load is applied to the bridge. If the bridge can carry this load without distress, the proof load test is success-ful, and the...conference paper 2021

(author)High-quality data plays a vital role in developing reliable image classification models. Despite that, what makes an image difficult to classify remains an unstudied topic. This paper provides a first-of-its-kind, model-agnostic characterization of image atypicality based on human understanding. We consider the setting of image classification...conference paper 2023

Yang, Z. (author), Rahimi, S. (author), Li, Z. (author), Dollevoet, R.P.B.J. (author)This paper presents a full finite element (FE) model of wheel-track interaction to study the wheel-rail impact noise excited by an insulated joint (IJ). The integration is performed in the time domain with an explicit central difference scheme. The vibratory behaviour of the track and wheel model are respectively validated with hammer test and...conference paper 2014

Lantsoght, E.O.L. (author), Yang, Y. (author), Tersteeg, R.H.D. (author), van der Veen, C. (author), de Boer, A (author)Proof loading of bridges is an option to study existing bridges when crucial information is lacking. When proof loading is chosen, the question arises which maximum load should be attained during the test to demonstrate sufficient capacity, and which criteria, the “stop criteria”, based on the measurements during the test, would indicate that...conference paper 2016

D'Aquilio, A. (author), Sileryte, R. (author), Yang, D. (author), Turrin, M. (author)In large sport’s buildings, a big part of energy can be saved by providing natural instead of mechanical ventilation. However, additional challenges arise while controlling airflow and temperatures in different zones. These measures<br/>highly depend on the shape, construction and ventilation openings, which are mostly decided in the early...conference paper 2016

Sileryte, R. (author), D'Aquilio, A. (author), Di Stefano, D. (author), Yang, D. (author), Turrin, M. (author)Parametric modelling allows quick generation of a large number of design alternatives. Ultimately, it can be combined with optimization algorithms for obtaining optimal performance-driven design. However, setup of design space for optimization is a very complex task requiring designer’s a priori knowledge and experience. Therefore, this paper...conference paper 2016

Yang, D. (author), Sileryte, R. (author), D'Aquilio, A. (author), Turrin, M. (author)Building performance simulations are usually timeconsuming. They may account for the major portion of time spent in Computational Design Optimization (CDO), for instance, annual hourly daylight and energy simulations. In this case, the optimization may become less efficient or even infeasible within a limited time frame of real-world projects,...conference paper 2016

Koekkoek, R.T. (author), Lantsoght, E.O.L. (author), Yang, Y. (author), Boer, A. de (author), Hordijk, D.A. (author)As the bridge stock in The Netherlands and Europe is ageing, various methods to analyse existing bridges are bemg studied. Proof loading of bridges is an option to study the capacity when crucial information about the structure is lacking. This information could be related to the material (for example, the effect of alkali-silica reaction on the...conference paper 2016

Yang, Y. (author), van der Veen, C. (author), Hordijk, D.A. (author), de Boer, A. (author)Assessment of the capacity of the existing infrastructures has become more relevant in the recent years. With regard to the concrete bridges, the shear capacity of a large amount of existing concrete slab bridges reinforced with plain (smooth) bars are of concern. However, it was argued that the shear formula that is currently adapted in the...conference paper 2016
