Special Issue Information

Dear Colleagues,

Concrete and composite materials both play important roles in structural engineering. The functions of concrete include the following: 1. Load bearing capacity: Concrete can withstand a large amount of pressure and weight, such as columns, walls, etc. 2. Seismic performance: Concrete can provide stable building structures during earthquakes. 3. Durability: Concrete is capable of resisting natural environment erosion and climate change, enabling buildings to have a longer lifespan. The functions of composite materials are as follows: 1. Strength and stiffness: Composite material is generally composed of two or more different materials with high strength and stiffness, such as insulation materials, reinforcement materials, etc. 2. Lightweight: Composite material is usually lighter than traditional materials, which can reduce the self weight of the structure and improve the load-bearing capacity of the building. 3. Corrosion resistance: Composite materials are not easily corroded by the natural environment and chemical substances, meaning that they are suitable for structures in special environments such as marine engineering. In summary, concrete and composite materials can meet the needs of different structures and improve the stability, durability, and safety of buildings.

This Special Issue will provide an overview of the existing knowledge on the new approaches regarding the application of concrete and composite materials in structural engineering. Submissions consisting of original research articles, theoretical and experimental work, case studies, and comprehensive review papers are welcome and will be considered for publication.

This study explores the mechanical properties of Glass Fiber-Reinforced Polymer (GFRP), a high-performance composite material, focusing on how varying diameters affect its tensile strength, modulus, and elongation. Experimental data obtained from three sets of tensile tests on 10, 12, and 25 mm bars helped establish a stress–strain relationship for GFRP reinforcements, considering diameter changes, and a formula for calculating the ultimate tensile strength based on diameter. Utilizing the weakest chain theory and the Weibull distribution, the research found that GFRP’s tensile strength diminished with increased diameter, while the elastic modulus behaves oppositely. The analysis, grounded in the weakest chain theory, identifies the specimen’s effective volume as a critical factor in the size effect of GFRP bars. Moreover, the study proves a significant size effect on GFRP’s tensile properties, validating the theory’s application in predicting the strength of GFRP bars of varying sizes and recommending a specimen length range of 30–40 times its diameter for standardization purposes.
