Risk based inspection of flood defence dams: An application to grass revetments
No full textIn The Netherlands, inspection and maintenance are essential for maintaining stringent flood protection standards. Flood defences are assessed every 12 years to ensure they meet their risk-based safety standards,which are given as legally-binding maximum failure probabilities. Between assessments, flood defence managers are subject to risk-maintenance requirements: they must ensure that the failure probability of the defence does not increase in excess of its safety standard. However, there is no prescribed methodology to meet this requirement. In the study presented here, we developed a method which enables flood defence managers to derive inspection strategies using visual inspection data that will allow them to meet their risk-maintenance requirements.We applied the method to the assessment of grass revetments on the outer slope of the Oesterdam, one of the dams of the Dutch Delta Works. The application illustrates how – using visual inspection data, degradation information, and a failure mechanism model – inspection intervals can be derived that will ensure the risk-maintenance requirements are met.Accepted Author ManuscriptHydraulic Structures and Flood Ris

Analisis ini dilatarbelakangi oleh kegiatan transaksi konversi cryptocurrency ke dalam mata uang rupiah yang sedang terjadi di Indonesia hal ini menjadi masalah karena kegiatan tersebut tidak ada peraturan yang jelas dan mengingat penggunaan cryptocurrency telah dilarang sebagai alat pembayaran di Indonesia, karena tidak ada negara yang memback up bitcoin sebagai mata uang. Analisis ini menggunakan metode penelitian pendekatan undang-undang dan di interpretasi dengan menggunakan metode gramatikal dan teologis. Berdasarkan hal tersbut maka dapat disimpulkan tidak adanya peraturan yang membahas secara spesifik mengenai konversi cryptocurrency (bitcoin) akan tetapi ada pemberitahuan dari pemerintah untuk hati-hati terhadap kegiatan ini dan adanya alasan cryptocurrency (bitcoin) dilarang sebagai alat pembayaran membuat penulis merekomendasikan bahwa kegiatan konversi cryptocurrency (bitcoin) ini dapat membahayakan masyarakat karena merupakan economic bubble dan melarang perusahaan yang memfasilitasi jual beli cryptocurrency untuk melanjutkan kegiatannya. Kata Kunci: Konversi, Cryptocurrency, Mata Uang ABSTRACT This article analyses conversion of cryptocurrency (bitcoin) into rupiah from the perspective of Bank Indonesia Regulation Number 18/40/Pbi/2016 concerning Payment Process. This analysis was initiated based on the issue over cryptocurrency conversion into rupiah while there is no clear regulation on the use of cryptocurrency and this conversion has been regarded invalid as a payment method in Indonesia because there are no countries backing up bitcoin as a currency. This analysis employed statute approach interpreted by grammatical and theological methods. The result concludes that there is no regulation specifically regulating the conversion of cryptocurrency (bitcoin) but there is still a notification from the government for people to be more careful for this activity and reasons are given over why cryptocurrency is banned as a transaction in payment. This issue leads to the recommendation made by the author that this activity could harm societies recalling that this is regarded as economic bubble and it is recommended that companies stop facilitating cryptocurrency transaction to execute any activities in the companies.

Lessons learned from data analytics, applied to the track maintenance of the dutch high speed line
No full textLife cycle performance and risk management are often mentioned as critical tasks for infrastructure managers. However, without proper data collection and analytics these tasks cannot be executed. This paper discusses lessons learned from a case where a data analytics approach was deployed when an unexpected phenomenon occurred on the Dutch High Speed Line (HSL-Zuid). In November 2014, it was found that large sections of the HSL-Zuid were affected by a severe type of rolling contact fatigue (RCF). The RCF resulted in deep cracks on top of the rail. These damages were unexpected as the rails were only 5 years in operation and these rails were expected to last about 20–25 years with proper maintenance. In this case, resulting in about 20 km of rail replacements and multiple additional grinding campaigns. As the causes of defects were unknown, the authors applied data analytics to evaluate the possible causes of the RCF. Several measurements of the infrastructure, maintenance and the rolling stock resulted in a set of parameters. Then, a bottom-up approach is proposed for evaluating the affected sections to find similar parameter values among these over the whole track. The idea was to look for parameter values which could explain why certain sections were affected by the defects while others were not. The outcomes of the analysis indicated that it is highly likely that one type of rolling stock was affecting the rails in the curves of the HSL-Zuid. As the track was designed at the high-speed sections for 220–300 km/h and this type of rolling stock was driving below design speed, different loading of the rails throughout the curves occurred. Lessons learned from this case do not only apply to the technical area of wheel/rail and vehicle/infrastructure interfacing, but also to the usage of data analytics itself and life cycle management. From this case study, it is discussed how data collection and analytics can be better embedded by (rail) infrastructure managers from an early stage of development and use of infrastructure. Further scientific development for infrastructure data analytics are also discussed.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Integral Design & ManagementRailway Engineerin

Critical proof load for proof load testing of concrete bridges based on scripted FEM analysis
No full textAs the bridge stock in The Netherlands and Europe is ageing, various methods to analyse the capacity of existing bridges are being studied. Proof load testing is one of the method to test the capacity of bridges by applying loads on the existing concrete bridges with small spans. Because of the fact that neither the actual traffic load nor the design traffic load required by Eurocode can be directly applied on the target bridge in real-life proof load testing, an equivalent wheel load has to be applied instead. The magnitude and the location of the equivalent wheel load is determined in such a way that it generates the same magnitude of inner forces in the cross section. Such calculation is usually done by linear finite element analyses (FEA). Whereas, different bridges have different geometry such as length, width, thickness, skewness, number of spans and lanes etc. For each configuration, FEA has to be done first to determine the loading position. The main aim of this paper is to study the relation between bridge geometry and unfavourable loading positions. Based on that, a guidance tool is developed for the determination of the critical proof load testing locations for the practice. To achieve this goal, a Python script has been developed using the general purpose FEM platform DIANA FEA. The script enables the automatic generation and analysis of a bridge model with different geometries and loading conditions. By applying the Eurocode Load Model 1 (LM1) at variable locations, the most unfavourable loading positions for the proof load are obtained at the corresponding boundary conditions. The output of the study provides a convenient tool for future proof load testing.Concrete Structure
Target reliability indices for existing quay walls derived on the basis of the LQI criterion
No full textGeneral frameworks for reliability differentiation have evolved over time and are mainly developed for new buildings. However, recommendations for existing quay walls are lacking. In this study target reliability indices for assessing existing quay walls were derived by economic optimisation and by evaluating the Life Quality Index criterion (LQI). In quay wall design, some dominant stochastic design variables are largely time-independent, such as soil and material properties. The influence of time-independent variables on the development of the probability of failure was taken into consideration in this study, because this affects the present value of future failure costs and the associated target reliability indices. The reliability indices obtained in accordance with the LQI acceptance criterion were a little lower than the target reliability indices derived by economic optimization. The target reliability indices obtained for existing quay walls depend on the consequences of failure and the remaining service life. If failure modes of a quay wall are largely time-invariant and already survived the first period of the service life, the residual probability of failure is lower for an existing quay wall compared to a new quay wall. Hence, this should be considered in the determination of target reliability indices. The method of approach to assess the development of reliability over time can also be used for evaluating target reliability indices of other civil and geotechnical structures.Hydraulic Structures and Flood Ris
