Conversational futures: Emancipating conversational interactions for futures worth wanting

We present a vision for conversational user interfaces (CUIs) as probes for speculating with, rather than as objects to speculate about. Popular CUIs, e.g., Alexa, are changing the way we converse, narrate, and imagine the world(s) to come. Yet, current conversational interactions normatively may promote non-desirable ends, delivering a...

Towards a uniform and optimal approach for safe NLFEA of reinforced concrete beams: Quantification of the accuracy of multiple solution strategies using a large number of samples

Application of Nonlinear Finite Element Analysis (NLFEA) is lagging behind the many digital advances in the structural engineering practice. This is due to the need for codes and standards. To help development of these codes and standards, 119 solution strategies were developed with different assumptions and choices for the concrete constitutive...

Reliability of Ultimate Limit State Design in Finite Elements and Compliance with Eurocode 7

Geotechnical design problems may be characterized by a certain degree of uncertainty, due to insufficient soil data and transformation of test results in soil parameters. In common practice, engineers perform deterministic analyses according to design standards as Eurocode 7, where the uncertainties are taken into account through partial factors...

Jib Rest Design for Crane Barge Type CB6324 - A New Design Approach

The Damen Crane Barge type CB6324 is a transhipment barge, designed to operate in harbours, inshore and in near coastal waters worldwide, mainly for the on- and offloading of bulk carriers. In the second generation of this crane barge, optimization of the equipment and overall design is sought, increasing usability of the barge and reducing...

Geotechnical Ultimate Limit State Design Using Finite Elements

Displacement-based finite element calculations are primarily used for serviceability limit state (SLS) analysis, but the finite element method also offers possibilities for ultimate limit state (ULS) design in geotechnical engineering. The combined use of SLS and ULS calculations with partial safety factors according to the different design...

Bezwijkveiligheid boortunnels

Met de bouw van de Tweede Heinenoordtunnel is in Nederland een omvangrijk meerjaren onderzoeksprogramma gestart om de aanvankelijke nationale kennisachterstand op het gebied van geboorde tunnels in te lopen. Onderzoek naar het constructiegedrag van gesegmenteerde boortunnels maakt deel uit van dat programma. In dit kader is in 1999 de grote...
