van Calcar, C.J. (author), de Boer, Bas (author), Blank, B. (author), van de Wal, Roderik S W (author), van der Wal, W. (author)The Earth’s surface and interior deform due to a changing load of the Antarctic Ice Sheet (AIS) during the last glacial cycle, called Glacial Isostatic Adjustment (GIA). This deformation changes the surface height of the ice sheet and indirectly the groundling line position. These changes in surface height and grounding line position influence...abstract 2021

van der Wal, W. (author), van Calcar, C.J. (author), de Boer, Bas (author), Blank, B. (author)</p><p class="MsoNormal">Over glacial-interglacial cycles, the evolution of an ice sheet is influenced by Glacial isostatic adjustment (GIA) via two negative feedback loops. Firstly, vertical bedrock deformation due to a changing ice load alters ice-sheet surface elevation. For example, an increasing ice load leads to a lower bedrock...abstract 2020

(author)Information on the history of architecture is embedded in our daily surroundings, in vernacular and heritage buildings and in physical objects, photographs and plans. Historians study these tangible and intangible artefacts and the communities that built and used them. Thus valuable insights are gained into the past and the present as they...book chapter 2023

(author)Built form dominates the urban space where most people live and work and provides a visual reflection of the local, regional and global esthetical, social, cultural, technological and economic factors and values. Street-view images and historical photo archives are therefore an invaluable source for sociological or historical study; however,...book chapter 2019

de Boer, S. (author), Karpel, M. (author), Sodja, J. (author)A new flutter test version of the Parametric Flutter Margin (PFM) method, specifically applied to wings undergoing large deflections is presented. The PFM method adds a stabilising parameter, such as a stabilising mass, to the model such that the flutter velocity is increased. By exciting the stabilising mass in one of the primary (i.e., x, y...conference paper 2023

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

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
