Reliability updating for lateral failure of historic quay walls

The historic canal walls of Amsterdam, stretching 200 km in total, are constructed as a masonry wall on a timber deck supported by vertical timber piles. Understanding the resistance against lateral failure of these quays has been challenging due to uncertainties in their working principles, geometry, soil and structural properties. This...

Amsterdam quays under pressure: Modelling and testing of historic canal walls

Amsterdam faces the challenge of maintaining a domain of 200 km historic quay walls, which is a vital part of the city’s historical landscape. Many quays are currently in poor condition and require renovation or replacement in the near future, significantly impacting the city. The quay walls can be up to 300 years old and their structure...

Collapse of the Grimburgwal, a historic quay in Amsterdam, the Netherlands

A quay wall directly next to a building, both dating from around 1870, collapsed along the Grimburgwal in Amsterdam, the Netherlands, on 1 September 2020. The historic quay wall consisted of a masonry wall, built of a timber deck supported by several rows of timber piles of about 12 m long. As over 200 km of such quays exists in Amsterdam and...

Analytical model for laterally loaded pile groups in layered sloping soil

The historic canal wall structures in many Northern European cities have been built as masonry walls on a timber deck founded on timber piles. For analysis of the resistance of those structures and assessment of their remaining service life, suitable and accurate calculation models are needed. Thereto an analytical method was developed for...

Bezwijken Grimburgwal: Leerpunten voor het Amsterdamse areaal

In dit rapport is via een forensic engineering aanpak een eerste analyse gegeven (rapid assessment, RA) van het bezwijken van de Grimburgwal (GBW) op 1 september 2020. Het doel van het onderzoek is om te achterhalen welke lessen zijn te leren van het bezwijken van de Grimburgwal voor de overige kades in Amsterdam. De volgende onderzoeksvragen...

Discovering Software License Constraints: Identifying a Binary’s Sources by Tracing Build Processes

With the current proliferation of open source software components, intellectual property in general, and copyright law in particular, has become a critical non-functional requirement for software systems. A key problem in license compliance engineering is that the legal constraints on a product depend on the licenses of all sources and other...

Methods and Techniques for the Design and Implementation of Domain-Specific Languages

Domain-Specific Languages (DSLs) are programming language aimed at a particular problem domain, e.g. banking, database querying or website page lay-outs. Through the use of high-level concepts, a DSL raises the level of abstraction and expressive power of the programmer, and reduces the size of programs. This dissertation covers various aspects...

Declaratively Programming the Mobile Web with Mobl

A new generation of mobile touch devices, such as the iPhone, Android and iPad, are equipped with powerful, modern browsers. However, regular websites are not optimized for the specific features and constraints of these devices, such as limited screen estate, unreliable Internet access, touch-based interaction patterns, and features such as GPS....

Static Consistency Checking of Web Applications with WebDSL

Modern web application development frameworks provide web application developers with highlevel abstractions to improve their productivity. However, their support for static verification of applications is limited. Inconsistencies in an application are often not detected statically, but appear as errors at run-time. The reports about these...

Code generation by model transformation: A case study in transformation modularity

The realization of model-driven software development requires effective techniques for implementing code generators for domain-specific languages. This paper identifies techniques for improving separation of concerns in the implementation of generators. The core technique is code generation by model transformation, that is, the generation of a...

How to construct the camel: A Dutch museum for architecture and spatial design

Welke kameel wordt daar gebouwd?: Ideeën voor een museum over architectuur en ruimtelijke vormgeving in Nederland

Dit boekje gaat niet over een kameel maar over een museum. Een museum voor architectuur en ruimtelijke vormgeving wel te verstaan. De auteur wil ideeën aandragen voor de stichting van een dergelijk museum in Nederland. Net zoals een kameel een dier van vlees en bloed is, zo is ook een architectuurmuseum een levend 'geval' dat niet simpelweg...
