Strengthening of Reinforced Concrete Structures with Carbon Reinforced Concrete—Possibilities and Challenges

CivilEng, 2022
The strengthening of existing reinforced concrete structures (RC) with carbon reinforced concrete (CRC) has a high potential to save resources and to increase the lifespan of the whole strengthened structure immensely. However, when strengthening structures with CRC, in some cases, failure due to concrete cover separation is detected, leading to the ...

Determination of Stiffness of the Connections of Composite Steel and Concrete Bridge Deck by the Limit Permissible Deflections

The Baltic Journal of Road and Bridge Engineering, 2013
The composite steel and concrete structures are used for constructing bridge floors and others buildings. The joint action of composite structures as well as their economic efficiency depends on the connection between the layers, i.e.

Predictive Stress Modeling of Resilient Modulus in Sandy Subgrade Soils

Infrastructures, 2023
The mechanical properties of pavement materials are crucial to the design and performance of flexible pavements. One of the most commonly used measures of these properties is the resilient modulus (Er). Many different models were developed to predict the
