Considerations on the partial safety factor format for reinforced concrete structures accounting for multiple failure modes

Aurelio Muttoni, Qianhui Yu, Miguel Fernández Ruiz

The increasing usage of nonlinear analyses for the design of reinforced concrete structures and the necessity of codes of practice to provide a consistent safety format for them is one of the challenges that new generations of codes of practice are facing. ...

Fire performance evaluation of GFRP-balsa sandwich bridge decks

Niloufar Vahedi

Bridges are a critical component of national infrastructures and economies. A significant percentage of bridges built all around the world are made of reinforced concrete which according to building codes have a life span between 80-100 years. However, str ...

Development of a road bridge digital twin for simulating traffic loadings

The bridge over the Venoge, built in 1966 and extended in 1997, is a composite bridge located on the highway between Lausanne and Geneva. The aim of this thesis will be to develop a digital twin of this bridge, which consist of a digital representation as ...

Auto-tuning ensemble models for estimating shear resistance of headed studs in concrete

Xianlin Wang, Yuqing Liu

The shear resistance of headed studs is of paramount importance for the design of steel-concrete composite structures and an accurate predictive model is highly needed. Ensemble learning is expected to be a powerful solution while it relies on laborious se ...

On the compressive and bond strength of reinforced concrete as structural properties

Francesco Rafael Alberto Moccia

Traditionally, the concrete strength is measured on cubes or cylinders having normalized dimensions, suitable vibration and curing conditions and their strength is assessed in laboratory under fast loading rates. However, the in-situ strength of structural ...

Investigation of fatigue damage in a RC deck slab due to moving loads through long-term monitoring of a road viaduct

Eugen Brühwiler, Imane Bayane

The behavior of reinforced-concrete structural elements under moving loads involves many complex parameters related to material properties, vehicle loading, environmental changes and structural response. It is difficult to generate the real conditions of l ...

Taylor & Francis2021

One of the most instrumental aspects governing the response of structural concrete at ultimate limit state refers to the possibility of developing smeared cracking patterns within a member (associated normally to the presence of sufficient reinforcement fo ...

Spalling of concrete cover induced by reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Rafael Alberto Moccia

This paper investigates the phenomenon of cover spalling in reinforced concrete induced by bond or by the action of an inner pressure. This research is based on an experimental programme comprising a series of bond tests and a series of tests with inner-pr ...

2021

Existing bridges in reinforced concrete (RC) need to be enhanced in order to comply with utilization and safety requirements of future use, in particular for higher traffic loads. Such enhancements comprise strengthening to increase the structural resistan ...
