A novel mechanical clamp for strengthening of steel members using prestressed CFRP plates

Alain Nussbaumer, Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

Strengthening of existing steel members using prestressed carbon fiber reinforced polymer (CFRP) plates has certain advantages over non-prestressed reinforcement, especially due to the reduction in permanent tensile stresses acting on the steel members. Ho ...

An experimental investigation into bond behavior of prestressed CFRP to steel substrate

Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

Nowadays, strengthening of existing steel structures using advanced carbon fiber reinforced polymer (CFRP) composites is becoming a common technique due to the unique advantages of the material such as light weight, high strength and fatigue endurance, as ...

Design versus Assessment of Concrete Structures Using Stress Fields and Strut-and-Tie Models

Aurelio Muttoni, Filip Niketic, Miguel Fernández Ruiz

Stress fields and strut-and-tie models are widely used for design and assessment of structural concrete members. Although they are often used in the same manner for both purposes, developing suitable stress fields and strut-and-tie models for the design of ...

Stress Fields for the analysis of the faillure load and cracking state of dapped-end beams (Aplicación de modelos de campos de tensiones para el análisis en servicio y rotura de apoyos a media madera)

Aurelio Muttoni, Miguel Fernández Ruiz, Jaime Mata Falcon

The automatic generation of elastic-plastic stress fields (EPSF) for structural concrete members by means of the finite element method has been demonstrated as a suitable approach for the design and assessment of D regions. This methodology allows accounti ...

Investigation of a new steel-concrete connection for composite bridges

Jean-Paul Lebet, Dimitrios Papastergiou

A new type of connection for steel-concrete composite bridges was developed by the Steel Structures Laboratory of Ecole Polytechnique Fédérale de Lausanne. Resistance to longitudinal shear is based on the development of shear stresses in the confined inter ...

Dynamic Brazilian Tests of Granite Under Coupled Static and Dynamic Loads

Yang Zou, Xing Li, Gang Li

Rocks in underground projects at great depth, which are under high static stresses, may be subjected to dynamic disturbance at the same time. In our previous work (Li et al. Int J Rock Mech Min Sci 45(5):739–748, 2008), the dynamic compressive behaviour of ...

Failure of Ceramic Composites in Non-Uniform Stress Fields

Varun Parameswaran Rajan

Continuous-fiber ceramic matrix composites (CMCs) are of interest as hot-section components in gas turbine engines due to their refractoriness and low density relative to metallic alloys. In service, CMCs will be subjected to spatially inhomogeneous temper ...

Alternative stress definition and residual stress effects in fatigue design of welded tubular structures

Alain Nussbaumer, Claire Acevedo, Luís Costa Borges, Farshid Zamiri Akhlaghi

Steel tubular truss are lightweight, aesthetical and used in many different applications. These structures are sensitive to fatigue and specific verification methods have been developed for them, in particular by CIDECT [2001]. Due to assembly and welding, ...
