Special Issue Information

Dear Colleagues,

Concrete and composite structures are two kinds of traditional structures that have been widely used in engineering practice. Today, the properties of materials, members and structures can be studied more comprehensively, deeply and systematically with the progress of modern research means. Simultaneously, with the emergence and development of new materials, such as sustainable concrete, UHPC, high-strength steel and FRP, an increasing number of novel members and structures with higher performance and better environmental friendliness are emerging.

It is our pleasure to announce this Special Issue of Buildings, which will focus on the current progress of concrete and composite structures. The objective of this Special Issue is to solicit articles related to the material development, structural performance and applications of concrete or composite structures. We hope to present the latest and most up-to-date research findings in this field.

Interested authors can submit their manuscript—full papers, communications, case studies and reviews—with a focus on the research and applications of concrete or composite structures, including (but not limited to) the following topics:

  • Mechanisms, durability and microstructures of steel and concrete materials;
  • Architecture design;
  • Behaviours of novel concrete or composite members;
  • Concrete or composite structures under extreme loading conditions, such as seismic, fire, impact and blast;
  • Damage evaluation and rehabilitation of concrete or composite members/structures;
  • Field monitoring and case studies.

To achieve sustainable development during urbanization, construction waste is recycled for use as an aggregate in recycled concrete (RC). To determine the influence of the brick content in coarse recycled aggregates on the damage sustained by the resultant RC, the RC was first divided into seven phases: natural crushed stone, old gravel inside waste concrete, bricks, new mortar, old mortar on waste concrete surfaces, and new and old interface transition zones. The Monte Carlo method was then applied to establish a two-dimensional random aggregate model of the RC made with coarse brick aggregates. The ABAQUS software package was used to simulate a uniaxial compression test, the results of which were combined with those of a macro-test to determine the internal damage change rule of brick-containing RC. The stress–strain curves obtained from the simulation coincided well with that of the macroscopic tests. As the brick content increased, the damage zone inside the specimen and the number of microcracks increased. The stress concentration area decreased, as indicated by a lower compressive strength in the macro-test. The results indicate that higher brick contents in RC yield more initial damage inside the concrete and a lower compressive strength. Full article

In this paper, a finite element model of concrete-filled steel tubular (CFST) columns under compression and lateral impact is developed and validated against previous experiments. After analyzing the influence of axial compression on the impact performance of CFST columns, the effects of eccentricity, material strength, and steel ratio on the dynamic compression-bending performances of CFST columns subjected to lateral impact are discussed. The simulated results show that at different axial compression ratios, CFST columns show overall bending failure under lateral impact. The axial force ratio below 0.2 shows a positive effect on the impact resistance of CFST columns, otherwise the axial force would degrade the impact resistance of CFST columns. Eccentricity has a negative effect on the dynamic compression-bending performance of CFST columns. The increase in the concrete strength has little effect on the dynamic compression-bending performance of the CFST columns under lateral impact and eccentric compression. The increases in steel strength and steel ratio can improve the dynamic compression-bending performances of the CFST columns under lateral impact and eccentric compression. Even though the prediction formula for the dynamic compression-bending performance of CFST columns shows good fitness with the simulated results, it is modified to have sufficient strength reserves for design applications.
