Numerical analysis of concrete beams retrofitted with carbon fibre reinforced polymer under impact loading Ghent University
Low-velocity impact behaviour of plain concrete beams Ghent University
Concrete structures are designed and constructed to serve their anticipated service life, generally with minimal consideration of accidental loads such as impact or explosion. The behaviour of reinforced concrete structures under impact loads has been widely discussed in the last decades, however, there are few studies on the behaviour of plain concrete under impact loading. This paper presents a finite element model of plain concrete beams ...
Blast mitigation of reinforced concrete hollow core slabs using CFRP as externally bonded reinforcement Ghent University
One of todayU+2019s state-of-the-art techniques for strengthening of reinforced concrete structural el-ements is the use of carbon fiber reinforced polymer (CFRP) composite strips as externally bonded reinforce-ment (EBR). This is justified for quasi-static loads by the high strength, light weight and excellent durability characteristics of CFRP EBR in combination with their ease of application. The present paper deals with the performance of ...
New technique to protect RC slabs against explosions using CFRP as externally bonded reinforcement Ghent University
In recent years, numerous explosions related to industrial accidents and terrorist attacks causing loss of life and severe damage to infrastructures have occurred all over the world. However, existing reinforced concrete (RC) structures are not designed to resist blast loads and could collapse after the incident. As a consequence, the emerging challenge of critical infrastructure protection has been recognized and nowadays there is a desire to ...
Numerical analysis of debonding between CFRP strips and concrete in shear tests under static and blast loads Ghent University
The present paper deals with the finite element (FE) analysis of the bond slip between concrete and carbon fiber reinforced polymer (CFRP) strips in a single bond shear test under static loads and in a double bond shear test under blast loading. A plastic damage material model and an elastic material model are used to model the concrete prism and the unidirectional CFRP strip, respectively. The bond interface between concrete and CFRP strip is ...
Numerical modelling of the debonding between CFRP strips and concrete in shear tests under static loads using different approaches Ghent University
The present paper deals with the finite element (FE) analysis of bond slip between concrete and carbon fiber reinforced polymer (CFRP) strips in a single pull-out test under static loads. The commercial software LS-DYNA is used to simulate the test set-up using a plastic damage material model and an elastic material model for the concrete prism and the unidirectional CFRP strip, respectively. The bond interface between the concrete and the CFRP ...
Increasing the reactivity of modified ferro silicate slag by chemical adaptation of the production process Ghent University
Modified Ferro Silicate (MFS) slag can be used as an alternative Supplementary Cementitious Material (SCM)to make concrete sustainable and to enhance the circular economy. Given their pozzolanic characteristics,these MFS slags can be used as SCM. However, due to the low CaO content of the MFS slag, they haveslower reaction and dissolution rate than Ca rich by-products such as Ground Granulated Blast Furnaceslags (GGBFS). Increasing latent ...
