Special Issue Information

Dear Colleagues,

A variety of advanced metal materials, involving high-strength steel, stainless steel, aluminium alloy, and bimetallic steel, have been applied to enhance the safety and durability of the building and bridge structures under the action of earthquake, fire, moving loading, impact, corrosion, etc. Unlike low-alloy mild steel, these metal materials exhibit different mechanical properties, probably leading to different mechanical behavior and responses for the components and structures. In order to boost the application of these advanced metal materials into civil structures, this Special Issue, entitled “Mechanical Properties of Advanced Metal Structures in Civil Infrastructure”, aims to reveal the basic mechanical characteristics of these metal materials and to develop advanced numerical simulation techniques, analysis methods, and design theories for the corresponding joints, members, and structures. Both original research articles and reviews are welcome. Topics of interest will cover, but are not limited to, the following aspects:

(1) Monotonic and cyclic constitutive models;

(2) Buckling behavior;

(3) Seismic resilience;

(4) Fire resistance;

(5) Fatigue cracking mechanism and strength;

(6) Machine-learning-based evaluation and design method.

We look forward to receiving your contributions.

Steel-fiber reinforced concrete (SFRC) has the advantages of high strength, durability, and crack prevention ability. Studies on the compressive strength, tensile strength and flexural behavior of SFRC have been carried out by many researchers. In this paper, the toughness of SFRC along with the bond behavior between SFRC and reinforcement were investigated. Hooked-end and straight steel fibers were chosen in the toughness tests of SFRC. The test results show that the SFRC mixtures with hooked-end steel fibers exhibit higher toughness. In addition, hooked-end steel fibers were chosen to be mixed in the SFRC to demonstrate the bond behavior between SFRC and reinforcing bars. Different embedment lengths were considered in the tests to show the influence of the anchorage area on the bond–slip responses in the pull-out tests. The failure modes for different specimens were exhibited. The results show that the embedment length more than 5 times the bar diameter causes tensile failure of the reinforcement, while the embedment length of 3 times the bar diameter causes pull-out failure of the reinforcement.

Welding residual stresses significantly influence the mechanical behavior of hollow section joints, especially in the pivotal connection zones of steel structures employed in construction. The research object of this study is the Q355 steel square tube–plate Y-joint welded using Gas Metal Arc Welding (GMAW) with CO2 Shielding. The thermodynamic sequence coupling method was employed to simulate the temperature field, microstructure distribution, and welding residual stresses in square tube–plate Y-joints. Based on the monitored temperature field data and the cross-sectional dimensions of the weld pool, this study calibrated the finite element model. Subsequently, the calibrated finite element model was employed to analyze the influence of microstructural phase transformations and welding sequences on the welding residual stresses in square tube–plate Y-joints. The research findings indicate that the peak transverse welding residual stresses in the branch pipes of the four joint zones were lower when considering the phase transformation effect than when not accounting for it in the calculations. There was no significant difference in the transverse and longitudinal welding residual stresses on the surface of branch pipes under the three welding sequences. However, there were certain differences in the microstructural content of the weld zones under the three welding sequences, with the martensite content in the third welding sequence being significantly lower than that in the other two sequences.
