Summary: The aim of the research was to create a model of steel fibre distribution in a Steel Fibre Reinforced Concrete space using statistical probability means. Four statistical distributions were examined to find the best fit for describing fibre settling phenomenon caused by manufacturing process conditions. The chosen statistical distribution was adapted to create a model taking into account technological conditions and concrete properties, showing good agreement with real fibre distribution.

Summary: Experimental fatigue tests were conducted on pre-slipped, hooked-end steel fibre reinforced concrete (SFRC) at a single fibre level. The results showed that as the load level and pre-slip increased, fiber rupture and fiber pull-out became common failure mechanisms, with fiber pull-out being the dominant mechanism at the highest load level and pre-slip. Additionally, X-ray Computed Tomography (CT) scans were used to validate the pre-slip levels and failure mechanisms of the tested specimens.

Summary: The present study evaluated the effect of vibration time on steel fibre distribution and flexural behaviors of different flowability SFRC. The results showed a correlation between vibration time and SFRC flowability, increasing vibration time resulted in settlement of steel fibres to the bottom layer and segregation of the concrete matrix, leading to reduced flexural strength, toughness, and fracture energy.

Summary: This text discusses the application of 3D printed plastic spatial reinforcing elements in civil engineering. Despite the lower mechanical properties of 3D printed plastics compared to traditional steel re-bars, the spatial geometric shapes of plastic reinforcement can minimize some of these differences. Experimental results show that the properties of plastic-mortar elements are similar to good-quality steel fiber-reinforced concrete, making them a possible substitute for steel reinforcements. Future research directions and current applications are also discussed in the article.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
