Summary: The flexural beam test EN 14488-3 is a reference for characterizing the post-cracking tensile response of fibre-reinforced sprayed concrete (FRSC). The double punch test (DPT) and double-edge wedge splitting (DEWS) test offer alternative approaches for simplifying the assessment of post-cracking response of fibre-reinforced concrete. Results show high correlations between these tests and their ability to predict the constitutive model of FRSC.

Summary: This paper presents a systematic experimental study on the dynamic compressive behaviour of recycled tyre steel fibre (RTSF) reinforced concrete. Results show that with increasing RTSF content, the slump of concrete was reduced while its air content was increased. The compressive strength of concrete at various strain rates went up with the increase of RTSF content from 0 to 0.75% but reduced with the further increase of RTSF content from 0.75% to 1.25%. The optimal dosage of RTSF for concrete was found to be 0.75% for workability, compressive strength, and dynamic compressive performance.

Summary: The quality control of FRSC for tunnel linings has advanced in recent years by using small-scale tests to evaluate the mechanical behavior of FRSC. This study combines experimental and numerical investigations to assess the predictive capability of constitutive models derived from small-scale tests for larger panels. The results confirm the correlation between the new and traditional approaches and demonstrate the viability of small-scale tests for evaluating FRSC behavior.

Summary: This study conducted tests on circular fibre-reinforced polymer-concrete-steel hybrid multitube concrete columns, finding that they have excellent axial load and deformation capacities, suitable for engineering structures. Comparison between test results and model predictions revealed that the existing model can reasonably predict axial load-strain behavior but largely underestimates ultimate strain. Further research may help in developing a more accurate model.

Summary: The systematic study on the electrical resistivity of steel fibre-reinforced concrete with different fibre contents revealed that the addition of fibres leads to a significant decrease in resistivity. The study also showed that an increase in concrete porosity results in lower resistivity. Furthermore, the influence of concrete composition on resistivity weakens with an increase in fibre content, while a higher fibre dosage generally leads to a decrease in resistivity, with slight variations depending on the type of steel fibres.

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: Anchorage to concrete is a common application in construction, and bonded anchors formed by polymer adhesive injection are widely used due to their flexibility and high load capacities. The condition of the anchor installation borehole and the quality of the drilling can affect the load-bearing performance and installation quality. The use of steel fiber-reinforced concrete is expected to increase, and it is important to consider the design and product certification for anchors in such concrete.

Summary: The use of steel-basalt fibre composite bars (SBFCBs) effectively addresses the corrosion and poor ductility issues in steel-reinforced and pure FRP-reinforced concrete beams, respectively. The study investigates the flexural behavior of SBFCB-reinforced concrete beams through testing eleven beams with different reinforcement methods, aiming to provide design and application reference. The research encompasses the failure mode, ultimate bearing capacity, strain of concrete and reinforcement, crack distribution, and the effects of different reinforcement methods and equivalent reinforcement ratios. The results indicate the influence of the equivalent reinforcement ratio on the failure mode, cracking load values, yield load, ultimate load, and secondary stiffness of SBFCB-reinforced concrete beams, as well as the improved ductility and reduced crack parameters with increasing equivalent reinforcement ratio. The deduced formulas for yield load and ultimate bearing capacity show good agreement with the measured values, and a recommended maximum strain limit for SBFCBs is proposed.

Summary: A new composite structure, steel and steel fibre reinforced concrete (SSFRC) structure, is proposed by using steel fibres to replace stirrups and longitudinal rebars. Increasing the shaped steel ratio and steel fibre volume fraction can significantly enhance the deformation capacity and ductility coefficient of the specimen. By analyzing the effects of design parameters on structural performance, effective methods for increasing energy dissipation are revealed.

To achieve objectivity, the notion of objectivity is extended to curved spaces using methods from mathematical physics and Riemannian geometry, with symmetry groups as the basis for definition. A general mathematical framework is developed for computing observer fields in curved spaces, enabling objective computation of other measures.

Summary: We propose a new approach to render volumetric data, considering the Doppler effect of light. Similar to the acoustic Doppler effect, light waves also experience compression or expansion due to relative motion between emitter and observer. We achieve accurate volume rendering at interactive frame rates by employing spectral volume rendering and introducing a novel piecewise linear representation of the involved light spectra.
