Block loading fatigue of adhesively bonded pultruded GFRP joints

Thomas Keller, Anastasios Vassilopoulos, Roohollah Sarfaraz Khabbaz

The effect of loading sequence on the fatigue behavior of adhesively-bonded pultruded GFRP double-lap joints was experimentally investigated by applying different tensile and compressive block loading patterns. The observed failure modes were consistent wi ...

An Active Deployable Tensegrity Structure

Landolf-Giosef-Anastasios Rhode-Barbarigos

Tensegrity structures are spatial reticulated structures composed of cables and struts. Their stability is provided by a self-stress state among tensioned and compressed members. Although much progress has been made in advancing research into the tensegrit ...

Effect of tensile residual stresses on fatigue crack growth and S-N curves in tubular joints loaded in compression

Alain Nussbaumer, Claire Acevedo

The influence of welding tensile residual stresses on fatigue crack growth in bridge tubular K-joints is investigated through experimental testing of large-scale specimens. Crack development is monitored using the alternating current potential drop method. ...

A meso-mechanical model for concrete under dynamic tensile and compressive loading

Jean-François Molinari, Leonardo Snozzi, Fabrice Gatuingt

We present a computational model, which combines interface debonding and frictional contact, in order to investigate the response of concrete specimens subjected to dynamic tensile and compressive loading. Concrete is modeled using a meso-mechanical approa ...

Crushing and Flexural Strength of Slab-Column Joints

Aurelio Muttoni, Miguel Fernández Ruiz, Roberto Guidotti

In multi-storey buildings, columns are usually not continuous through the slabs to enhance ease of construction. Consequently, in slab–column joints, slabs have to carry column loads in addition to the shear and bending moments due to loads applied to the ...

Fire Performance of Water-Cooled GFRP Columns. Part II: Postfire Investigation

Thomas Keller, Yu Bai

The postfire mechanical performances of water-cooled full-scale GFRP cellular columns subjected to axial compression were evaluated after exposure to an ISO-834 fire from one side for periods of 60 and 120 mins. The elastic modulus and postfire buckling lo ...

Design optimization and dynamic analysis of a tensegrity-based footbridge

Ian Smith, Nizar Bel Hadj Ali, Landolf-Giosef-Anastasios Rhode-Barbarigos

Tensegrity structures are spatial structural systems composed of struts and cables with pin-jointed connections. Their stability is provided by the self-stress state in tensioned and compressed members. Although much progress has been made in advancing res ...

Fire endurance performance of cellular GFRP columns with water-cooling system

Thomas Keller, Christian Ludwig, Yu Bai

Experimental results on the fire endurance of full-scale glass fiber-reinforced polymer (GFRP) composite columns are reported in this paper. The pultruded four-cell profiles were first loaded to axial compression (uniform serviceability stress of 5 MPa) an ...

Post-punching behavior of reinforced concrete slabs

Yaser Mirzaei

Reinforced concrete flat slabs are extensively used in buildings and parking garages. Their design is governed by deflection at the serviceability limit state and punching shear at the ultimate limit state. When no punching shear reinforcement is provided, ...

Morphology and mechanical properties of isotactic polypropylene glass mat thermoplastic composites modified with organophilic montmorillonite

Jan-Anders Edvin Maansson, John Christopher Plummer, Sara Dalle Vacche, Chrystèle Houphouet-Boigny Favre

Satisfactory impregnation of glass fiber mats may be obtained with isotactic polypropylene/montmorillonite (MMT) nanocomposites under conditions comparable with industrial conditions. However, it is demonstrated here that the high melt viscosity of the nan ...
