(author), Duyzer, J.H. (author), Meijer, E.W. (author), Pronk, A. (author)Particulate matter exposure may cause adverse health effects. Although ultrafine particulate matter (UFP) is hypothesised to be particularly health relevant, the number of studies into personal UFP exposure is limited. Aim To increase insight where and when most UFP exposure occurs, in terms of exposure levels and peaks in microenvironments,...article 2017

Gentile, C. (author), Poggi, C. (author), Ruccolo, A. (author), Vasic, M. (author)metallic tie-rods are installed under all naves to support a portion of the lateral thrust exerted by vaults and arches. After the recent failure of one tie-rod, an extensive research program was carried out to characterize the metallic material and to evaluate the axial forces and the tensile stresses of the tie-rods through dynamic testing and...conference paper 2017

Pruiksma, J.P. (author), Breunese, J.N. (author), van Thienen-Visser, K. (author), de Waal, J.A. (author)This paper presents a new formulation of the Rate Type Compaction Model (RTCM) for sandstone based on the isotach concept. The RTCM was originally developed to explain the loading rate dependent compaction behaviour observed in laboratory test on unconsolidated and consolidated sandstone samples and the delayed subsidence behaviour above...article 2015

Steenbergen, R.D.J.M. (author), Vrouwenvelder, A.C.W.M. (author)In de recent verschenen ontwerp-NPR 1998 wordt uitgegaan van een streefwaarde van de veiligheid van bouwwerken onder aardbevingsbelasting. Daarbij vormt de in Nederland gangbare streefwaarde voor het individueel risico de belangrijkste inputparameter. Op basis van de voorgestelde betrouwbaarheidsindices worden rekenwaarden afgeleid. Die spelen...article 2015

Liu, G. (author), Nielsen, E. (author), Komacka, J. (author), Leegwater, G. (author), van de Ven, M. (author)Reclaimed asphalt (RA) that contains polymer-modified bitumen (PMB) offers a potential premium material contribution for recycling. This study investigated the influence of soft virgin bitumens on the chemical and rheological properties of three reclaimed PMBs from different "old" surface-layer asphalt mixtures in Europe. Although the PMB...article 2015

Ook wanneer wel direct voorzieningen waren opgenomen in het ontwerp, dan nog zou de problematiek zich hebben aangediend. In de praktijk bleken trillingen op te treden met hoge spanningsranges in grote aantallen, die volgens de analyses op basis van de norm vooraf niet...article 2015

Walraven, J. (author), Vrouwenvelder, A.C.W.M. (author)Tot voor kort leefde Nederland mee met de gevolgen van aardbevingen in de wereld, in de veronderstelling dat dit ver van ons bed was. Door de recente aardschokken in Groningen zijn in ons land andere ideeën ontstaan over de invloed van aardbevingen op de gebouwde omgeving. In dit artikel worden de herkomst en de karakteristieken van de Groninger...article 2015
