Special Issue Information

Dear Colleagues,

In recent decades, ultra-high-performance concrete (UHPC) has evolved as a popular material in the construction of new structures and strengthening of existing infrastructures, due to its outstanding workability, mechanical properties (e.g., compressive, tensile, and bond strengths), and chemical resistance compared to the conventional concrete. However, higher demands have been required for UHPC materials and their corresponding structures in recent complex structures, such as high-rise buildings, long-span bridges, and long tunnels. To this end, a number of innovative new UHPC materials and their corresponding application technologies have emerged. In order to promote the wider application of UHPC, we are calling for paper submissions to this Special Issue on UHPC Materials: Structural and Mechanical Analysis in Buildings. The aim of this Special Issue is to provide an overview of the recent innovations and advances in the fundamental and practical fields of UHPC materials and their composite structures, with a special focus on their corresponding structural and mechanical analyses in buildings. High-quality original research papers (e.g., theoretical research, experimental work, and case studies) and state-of-the-art reviews are encouraged that include, but are not limited to, the following topics:

  • Design, performance, and construction techniques of innovative UHPC materials (e.g., steel-free UHPC, and fast-hardening and low-shrinkage UHPC);
  • Design, performance, and construction techniques of innovative modular structures (e.g., beams, columns, slabs, and nodes) made from UHPC and other building materials;
  • Prefabricated modular construction and life-cycle assessment of UHPC modular structures;
  • Rehabilitation, repair, and retrofitting of existing buildings with UHPC;
  • Mechanical behavior of UHPC and its corresponding composite structures against the static (e.g., compression, tension, and bending) and dynamic (e.g., impact, fatigue, and seismic) actions;
  • Various research techniques (e.g., experimental studies, nonlinear finite-element analysis, and deep learning-based structural analysis and evaluation).

Ultra-high-performance concrete is widely used in bridge strengthening to improve mechanical performance and bridge durability. Interfacial bonding performance is a key factor in ensuring the effectiveness of ultra-high-performance concrete strengthening. The bending test of the UHPC–NC composite structure was carried out in this article. The effects of groove treatment type and epoxy resin bonding were considered to discuss the damage modes, load–deflection relationships, and strengths. The interfacial tensile strength of the UHPC–NC composite structure and the distribution pattern of cracks were clarified. The results of the test showed that (a) only 22.2% of the groove-treated specimens failed due to bonding surface failure, indicating that the UHPC–NC bonding surface has a high degree of reliability; (b) the strength of specimens with an epoxy adhesive interface was the lowest. It was only 21% higher than the pure normal concrete specimen, and the effective synergistic force of UHPC–NC cannot be achieved; (c) the specimens treated with a positive trapezoidal keyway exhibited the highest strength, with an increase of approximately 200% compared to the pure normal concrete specimens. The strength of bending specimens with right-angled and inverted trapezoidal grooves increased by approximately 100% compared with pure normal concrete specimens. Based on the established three-dimensional numerical model and the analysis of test results under economic and safe conditions, the positive trapezoidal keyway specimen exhibits superior interfacial bonding–tensile performances.

To investigate the design principles and simplified calculation model of large-size PBL-stiffened steel–concrete joints, this study uses a Y-shaped rigid frame-tied arch composite bridge as an engineering background. Based on deformation coordination theory, a combination of theoretical analysis and numerical simulation was employed to derive a simplified calculation model that accounts for boundary conditions such as the stiffness of steel beam end restraints and the local bearing effect of the bearing plate. Parametric analysis of the steel–concrete joint was conducted. The results indicate that the derived simplified calculation model exhibits good accuracy and is suitable for calculating force transfer in various components of the steel–concrete joint under different boundary conditions. Using the simplified model, the effects of parameters such as steel–concrete joint length, connector stiffness, and structural axial stiffness on the axial force transfer in primary force-bearing components (connectors and bearing plates) were studied. The findings reveal that an excessively long steel–concrete joint does not effectively reduce maximum shear force; variations in connector stiffness primarily affect connectors farther from the bearing plate without changing the shear force distribution. Increasing the axial stiffness of the steel structure within a certain range can improve the maximum shear force in connectors, whereas increasing the axial stiffness of the concrete structure has the opposite effect.
