Energy dissipation in adhesive and bolted pultruded GFRP double-lap joints under cyclic loading

Thomas Keller, Sonia Yanes Armas, Ghazaleh Eslami

Fiber-reinforced polymer (FRP) structures, due to their low mass, are valuable alternatives to traditional steel or concrete structures in seismic areas. However, to resist seismic actions, FRP structures must be able to dissipate a significant amount of i ...

Characterization of mortar-timber and timber-timber cyclic friction in timber floor connections of masonry buildings

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida

The seismic performance of buildings depends critically on the stiffness and strength of storey diaphragms. Whilst for modern reinforced concrete or steel structures the connection between floors and lateral resisting members is often assumed as monolithic ...

Application of Sustainable Bamboo-Based Composite Reinforcement in Structural-Concrete Beams: Design and Evaluation

Ian Smith

Reinforced concrete is the most widely used building material in history. However, alternative natural and synthetic materials are being investigated for reinforcing concrete structures, given the limited availability of steel in developing countries, the ...

Shear Strength of Members without Transverse Reinforcement Based on Development of Critical Shear Crack

Miguel Fernández Ruiz, João Tiago Ramos Bernardo de Santa Rita Simões, Francesco Cavagnis

The shear strength of beams and one-way slabs has been acknowledged for more than one century as one of the most complex, yet fundamental, topics to be addressed in structural concrete design. The experimental data used to investigate the phenomenon has tr ...

Housing Urban Masses Around a Green Yard. Typological comparison of modern examples in Copenhagen and Stockholm

Chiara Monterumisi

Since the aftermath of the II world-war till recent years, Nordic countries have looked as inspiring social and architectural models to the rest of Europe. Nevertheless, very few attentions have been addressed towards the first bases of their developments, ...

Characterization of interfacial transition zone in concrete prepared with carbonated modeled recycled concrete aggregates

Karen Scrivener

Treatment by accelerated carbonation has been widely studied to enhance the quality of recycled concrete aggregates (RCA) and hence the performance of new concrete produced with the RCA. This is often ascribed to the densification of RCA. This study invest ...

Meso-scale modelling of ASR in concrete: effect of viscoelasticity

Jean-François Molinari, Emil Gallyamov, Mauro Corrado, Roozbeh Rezakhani

A meso-scale numerical model for simulating damage in concrete due to ASR is presented. It accounts for the internal structure of concrete including aggregates and mortar. ASR sites are explicitly represented. This model is extended to account for viscoela ...

Understanding the carbonation of concrete with supplementary cementitious materials: a critical review by RILEM TC 281-CCC

Karen Scrivener, Barbara Lothenbach

Blended cements, where Portland cement clinker is partially replaced by supplementary cementitious materials (SCMs), provide the most feasible route for reducing carbon dioxide emissions associated with concrete production. However, lowering the clinker co ...

Comportement des éléments en béton armé fléchis sous charge cyclique

For various types of civil structures such as bridges, skyscrapers and other slender towers, oil rigs as well as runaways, dynamic loading is predominant. This holds true especially for bridges where loads have increased considerably in the last hundred ye ...

Cyclic thermomechanical response of fine-grained soil-concrete interface for energy piles applications

Lyesse Laloui, Elena Ravera, Melis Sütman

Understanding the behaviour of soil-structure interfaces is critical for addressing the analysis and design of energy geostructures. In this study, the interface failure mechanism of energy piles (where a shear band is detached from the surrounding soil th ...
