A multiscale experimental characterisation of Dutch unreinforced masonry buildings

Messali, F. (author), Esposito, R. (author), Jafari, S. (author), Ravenshorst, G.J.P. (author), Korswagen, Paul A. (author), Rots, J.G. (author)

In recent years, induced seismicity in the north of the Netherlands significantly increased. As a consequence, the seismic assessment of the built environment, which mainly consists of unreinforced masonry (URM) structures not designed for seismic loads, became of high relevance. Within this context, an extensive multiscale testing program has...

Building response to tunnelling- and excavation-induced ground movements: using transfer functions to review the limiting tensile strain method

Dalgiç, K.D. (author), Hendriks, M.A.N. (author), Ilki, Alper (author)

In this paper, limiting tensile strain method (LTSM) is reviewed, and advantages and disadvantages resulted from the simplicity of this method are examined in the light of the findings of the existing experimental and numerical studies. Using the viewpoint of the transfer functions for the LTSM, a more independent sight for the interpretation of...

Influence of the alkali-silica reaction on the mechanical degradation of concrete

Esposito, R. (author), Anac, C. (author), Hendriks, M.A.N. (author), Copuroglu, Oguzhan (author)

The alkali-silica reaction (ASR) is an important problem that has yet to be completely understood. Owing to the complexity of this<br/>phenomenon, a number of studies have been conducted to characterize its kinetics, its impact on the material, and its structural consequences.<br/>This paper focuses on the deteriorating impact of ASR on concrete...

Ageing effects of alkali-silica reaction in concrete structures

Esposito, R. (author), Hendriks, M.A.N. (author)

The alkali-silica reaction (ASR) is a long-term deterioration process, which produces a hydrophilic and expansive gel causing damage. The ASR acts on concrete as an ageing phenomenon, modifying the material on the basis of its stress state. Focussing on the mechanical degradation of concrete, estimated trends for the mechanical properties in...

Kappen, J.M.J. (author), Giardina, G. (author), Hendriks, M.A.N. (author), Rots, J.G. (author)

The development of infrastructure in major cities often involves tunnelling, which can cause damage to existing structures. Therefore, these projects require a careful prediction of the risk of settlement induced damage. The simplified approach of current methods cannot account for three-dimensional structural aspects of buildings, which can...

Variability of fatigue crack growth properties for 2024-T3 aluminium alloy

Oldersma, A. (author), Wanhill, R.J.H. (author)

Discussions between D-BAA and the NLR have shown that significant variability in fatigue crack growth properties is possible for the industry standard damage tolerant aluminium alloy, 2024-T3 sheet. This is important for two reasons: (1) design assumptions and (2) comparisons of different candidate materials, such as 6013-T6, with 2024-T3....

Damage assessment and preservation of an Egyptian silver vase (300 - 200 B.C.)

Wanhill, R.J.H. (author), Leenheer, R. (author), Steijaert, J.P.H.M. (author), Koens, J.F.W. (author)

An Egyptian metal vase from the Ptolemaic period was investigated metallurgically and fractographically. The metal is nearly pure silver, and chemical analysis indicates it was obtained from the cupellation of lead. Despite its high purity (in archaeological terms) the metal is severely cracked and embrittled, with fractures mainly along grain...
