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

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, Landolf-Giosef-Anastasios Rhode-Barbarigos, Nizar Bel Hadj Ali, Alberto Pascual Albi

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

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 ...

Coupled experimental and numerical investigation of structural glass panels with small slenderness subjected to locally introduced axial compression

Danijel Mocibob

Primary load-bearing glass constructions are often subjected to relatively important in-plane loads, transferred through so-called point-fixed connections. The according in-plane load introduction, structural resistance and failure mechanisms have been stu ...

Shear failure of pultruded FRP composites under axial compression

Thomas Keller, Yu Bai

When structural elements are subjected to compressive loads, the shear forces and stresses induced by second- order effects may lead to shear failure prior to compressive failure. This is particularly likely to occur in the case of pultruded glass fiber-re ...

Delamination of pultruded glass fiber-reinforced polymer composites subjected to axial compression

Thomas Keller, Yu Bai, Till Vallée

Axial compression experiments were conducted on pultruded E-glass fiber-reinforced polymer laminates of different slenderness. Second-order deformations greatly increased the bending moments and shear forces of slender specimens. Delamination failure occur ...

Structural behavior of multifunctional GFRP joints for concrete structures

Thomas Keller, Florian Riebel

A multifunctional all-FRP joint has been developed for the transfer of bending moments and shear forces in thermal insulation sections of concrete slab structures used in building construction. Tensile forces from moments are transferred by horizontal GFRP ...

The Matricellular Protein Periostin Is Required for Sost Inhibition and the Anabolic Response to Mechanical Loading and Physical Activity

Vincent Stadelmann

Periostin (gene Postn) is a secreted extracellular matrix protein involved in cell recruitment and adhesion and plays an important role in odontogenesis. In bone, periostin is preferentially expressed in the periosteum, but its functional significance rema ...
