To evaluate the behaviour of a single timber-concrete composite (TCC) T-beam, a simplified 2D finite element (FE) model in Abaqus is developed and validated using experimental tests and the Gamma method given in Annex B of EN 1995–1-1. The shear connection used in the beam consist of perfobond connectors, which are adhesively bonded to the timber beam. In the developed model, beam and shell finite
In timber-concrete composites (TCC), more researchers are trying to find the “ultimate” shear connector, which combines multiple advantages. Bonded steel plates are one of the possible solutions. This paper provides an analytical and a numerical approach, calibrated with previously conducted experiments, to predict the load carrying capacity, and corresponding governing failure mode, of perfobond
With the need of renovation in the current timber structures, use of a cement based layer is a popular solution, which improves the structural integrity and increases the structural mass. In this paper, the use of a lightweight concrete with dowel type connections is investigated since such a combination can serve for both new and existing structures. Two types of dowel connections are experimenta
In this paper, perforated shear connectors (perfobond), used extensively in steel-concrete composite (SCC) beams, are implemented in timber-concrete composite beams (TCC) and experimentally investigated. In contrast to its original use, the perfobond connector is connected with an adhesive to the timber beam while welded in the SCC solution. On the concrete slab side, connection is achieved using
In this paper, the use of low strength lightweight concrete in combination with glue-laminated timber (TLCC) is studied. Six series of push-out tests were conducted to assess the mechanical performance of the screw shear connection between these materials with a perpendicular and inclined (shearcompression)configuration with various screw diameters and lengths. The tests show that though low stren
Cu nanoparticles are widely used in different fields. Controlling the Cu oxidation state and the local strain is fundamental for optimizing its efficiency in processes, such as catalytic reactions. In this work, Cu nanoparticles were synthesized by using glucose as a reducing agent. Different synthesis conditions led to nanoparticles with a tunable local strain and Cu(0)/Cu 2O ratio. The amounts
In this paper we suggest that attention to the social practice of prepping, with its particular focus on how people navigate uncertain and potentially disastrous futures, can help broaden our understanding of forced migration. We argue that the emerging literature on doomsday prepping provides a particularly interesting vantage point from which to study the relationship between forced migration, t
In the African Great Lakes region, Hutu and Tutsi for the most part live peacefully side by side, while at times they have committed genocide and other atrocities in the name of ethnicity. On the one hand, ethnicity is strong enough to mobilize hundreds of thousands of ordinary Hutu peasants in Rwanda to kill, maim, and molest their Tutsi neighbors and to have the Tutsi-dominated army in Burundi s
The aim of this special issue of JEMS is to explore the inherent contradictions and tensions of transnational engagement and reveal how these are played out at different levels, intersecting with other social markers based on gender, class, ethnicity, etc. While transnational engagements span territories and transcend spatial fixation, they might also provide stabilised identities for those involv
Membrane glycoproteins frequently adopt different conformations when altering between active and inactive states. Here, we discover a molecular switch that exploits dynamic spatial rearrangements of N-glycans during such conformational transitions to control protein function. For the conformationally switchable cell adhesion glycoprotein α5β1 integrin, we find that only the bent-closed state
In most academic literature refugees are portrayed either as those who lack what national citizens have or as a threat to the national order of things. This article explores the effects of being excluded in such a way, and argues that Burundian refugees in a camp in northwest Tanzania find themselves in an ambiguous position, being excluded from the national order of things - secluded in the Tanza
This contribution explores the attempts by international humanitarian agencies and the post-genocide Rwandan state respectively to deal with exceptionality created by the genocide and return to normality. It does so by comparing two kinds of camps that deal with exceptional life: the refugee camps for Hutu who fled after the genocide and the Rwandan government's ingando re-education camps. While t
Based on thorough ethnographic fieldwork in a refugee camp in Tanzania this book provides a rich account of the benevolent "disciplining mechanisms" of humanitarian agencies, led by the UNHCR, and of the situated, dynamic, indeterminate, and fluid nature of identity (re)construction in the camp. While the refugees are expected to behave as innocent, helpless victims, the question of victimhood amo
