New perspectives on carbon reinforced concrete structures—Why new composites need new design strategies

Civil Engineering Design, Volume 5, Issue 5-6, Page 67-94, January 2024.
Abstract In civil engineering, carbon is typically regarded as a modern material to serve as reinforcement in concrete structures. Compared to steel reinforcement, it features two substantial benefits: It is not sensitive to corrosion, and has an enormously increased tensile strength.

Research on Flexural Properties and Flexural Toughness Evaluation Method of Steel Fiber Reinforced Cementitious Composites under Polar Low Temperatures

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
In this research, five groups of steel fiber reinforced cementitious composite (SFRCC) with different fiber volume content (0%, 0.5%, 1.0% 1.5%, and 2.0%) were designed to perform four‐point flexural tests on beam specimens to study the effects of polar temperature (20, 0, −25, −50, −75, and −100°C) and fiber volume content on the flexural properties ...

Application of Fully Connected Neural Network‐Based PyTorch in Concrete Compressive Strength Prediction

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
Compressive strength of concrete is an important parameter in the design of concrete structures and the prediction of their durability. Therefore, it is of great significance to predict the compressive strength of concrete. In this study, a fully connected neural network model is developed using the PyTorch framework to predict the compressive strength
