Experimental Strengthening of the Two-way Reinforced Concrete Slabs with High Performance Fiber Reinforced Cement Composites (HPFRCC) Prefabricated Sheets [PDF]

Journal of Rehabilitation in Civil Engineering, 2019
Reinforced concrete structures are required to be strengthened and retrofitted for various reasons, including errors during design and/or construction, so in most cases, strengthening of structural elements is much more economical than rebuilding the ...

Effect of span-thickness ratio on bending properties of high-strength glass fiber reinforced composite unidirectional plate

Journal of Aeronautical Materials, 2022
Based on the three-point bending test, the bending performances of S6C10-800/AC318 composite unidirectional plates with different span-thickness ratios (hereinafter referred to as unidirectional plates) were tested, and the effect of span-thickness ratio

Bending resistance of high performance concrete elements [PDF]

WIT Transactions on The Built Environment, 2008
Our previous research was focused on reactive powder concrete (RPC). In this article high performance concrete (HPC) will be analyzed. With high performance concrete both load bearing capacity and esthetics are combined to achieve superior structure. Due to lesser dimensions of walls and columns, space in high rise buildings is better utilized.

Boosting thermodynamic performance by bending space-time

Europhysics Letters, 2023
Abstract Black holes are arguably the most extreme regions of the universe. Yet, they are also utterly inaccessible to experimentation, and even just indirect observation poses significant technical challenges. The phenomenological approach of thermodynamics is uniquely suited to explore at least some of the physical properties of such ...

Deep learning improves performance of topological bending waveguides

Optics Express
This study introduced design informatics using deep learning in a topological photonics system and applied it to a topological waveguide with a sharp bending structure to further reduce propagation loss. The sharp bend in the topological waveguide composed of two photonic crystals wherein dielectrics having C
