Special Issue Information

Dear Colleagues,

Reinforced concrete (RC) remains one of the most widely used construction materials worldwide due to its versatility, strength, and cost-effectiveness. However, growing concerns related to aging infrastructure, environmental degradation, and increasing seismic and climate-related demands necessitate advanced research regarding improvements in the performance and durability of RC structures. This Special Issue aims to highlight recent innovations in the analysis, design, materials, and retrofitting techniques that enhance both the structural integrity and long-term sustainability of RC systems. Key areas of interest include advanced modeling and experimental studies on structural performance under extreme loads, the integration of smart and sustainable materials, novel construction methods, and the development of performance-based design strategies. In addition, we welcome the submission of articles that focus on the application of fiber-reinforced concrete (FRC), high-performance concrete (HPC), corrosion-resistant systems, alkali-activated HPC and UHPC, and life-cycle assessment (LCA).

By placing enhanced emphasis on resilient and sustainable infrastructure, this Special Issue provides a platform for researchers and practitioners to share innovative findings and practical solutions that address both current challenges and future needs.

In the literature, fatigue-loaded reinforced concrete (RC) beams have been the subject of several experimental investigations; however, few numerical studies have specifically examined this behavior. The primary goal of this study is to create and validate a comprehensive nonlinear finite element (FE) modeling framework that combines an existing concrete damage model with specialized modelling techniques (e.g., material modelling, structural modelling, mesh configuration) to forecast the behaviour of reinforced concrete beams under monotonic fatigue loads and track the failure progress. This was accomplished by implementing suitable constitutive and structural models pertaining to concrete and reinforcing steel using VecTor2 finite element software. The Lü concrete damage model, which accounts for the accumulated damage in the concrete at each loading cycle, was taken from the literature to enhance the numerical findings. A number of published experimental tests conducted under monotonic fatigue loading were used to assess the accuracy of the suggested numerical model. The obtained numerical results demonstrated that the FE model may be used to simulate the monotonic fatigue behaviour of various RC beam types. The monotonic fatigue results were significantly improved by applying the Lü concrete damage model. Additionally, the FE model was implemented into practice to offer valuable information on failure mechanisms, fracture patterns, and strain profiles at different loading cycles. Full article

This study investigates the effect of polypropylene fibers of different lengths (54 mm, 38 mm, 19 mm) on the mechanical and fracture properties of high-strength concrete. Unlike most existing research focusing on a single fiber length, this work evaluates a fixed hybrid ratio of 4:1:1, thereby addressing the synergistic action of macro- and microfibers. Three dosages were tested and compared to a reference mixture without fibers. Validation was performed by repeated testing of multiple specimens and statistical evaluation of mean values and standard deviations. The results showed that the optimal hybrid mixture (2.0/0.5/0.5 kg/m3) increased compressive strength by 28.7% and splitting tensile strength by 30.1% relative to the reference. Fracture toughness and specific fracture energy also improved significantly, demonstrating enhanced crack resistance and energy absorption. The main contribution of this work is to provide experimental evidence that a hybrid combination of polypropylene fibers at a fixed ratio can improve both mechanical strength and fracture resistance, with direct implications for durability and service life.
