Special Issue Information

Dear Colleagues,

Industrialization and intelligence are the new development directions in building structure research, which meet the development needs of performance, economy, environmental protection and other aspects needed to overcome modern challenges. Alongside technological development and innovation in past decades, the new building structure system represented by prefabricated buildings has become a hotspot in building industrialization. Meanwhile, artificial intelligence technology is emerging as a highly researched field and has shown broad prospects in assisting structure building. For these reasons, it is crucial to explore the developments and implementations of new structural systems, materials, methods and technologies in the wide realm of building structure industrialization and intelligence; therefore, this Special Issue of Buildings “Industrialization and Intelligence in Building Structures” will address these areas.

Topics include, but are not limited to, the following:

  • novel prefabricated buildings/structures;
  • novel structural materials;
  • high-performance concrete;
  • intelligent methods in structural analysis and design;
  • intelligent construction;
  • intelligent methods in structural health monitoring;
  • structural optimization.

Abstract
Corrugated steel plate shear walls (CSPSWs) have been widely utilized as lateral-resistant and energy-dissipating components in multistory and high-rise buildings. To improve their buckling stability, shear resistance, and energy-dissipating capacity, stiffeners were added to the CSPSW, forming stiffened CSPSWs (SCSPSWs). Evaluating the hysteretic [...] Read more.
Corrugated steel plate shear walls (CSPSWs) have been widely utilized as lateral-resistant and energy-dissipating components in multistory and high-rise buildings. To improve their buckling stability, shear resistance, and energy-dissipating capacity, stiffeners were added to the CSPSW, forming stiffened CSPSWs (SCSPSWs). Evaluating the hysteretic performances of SCSPSWs is crucial for guiding seismic design in engineering practice. In this paper, the dissipated energy values of the SCSPSWs with different parameters were calculated. Based on the obtained dissipated energy values, the elastoplastic design theory of stiffeners was established, and the evaluation of the hysteretic performance of the SCSPSWs was provided. Firstly, a finite element (FE) model for analyzing the hysteretic performance of the SCSPSWs was developed and validated against hysteretic tests of the CSPSW conducted by the authors previously. Subsequently, using the validated FE model, approximately 81 examples of SCSPSWs subjected to cyclic loads were analyzed. Hysteretic curves, skeleton curves, secant stiffness, stress distribution, and out-of-plane displacement were obtained and examined. Results indicate that increasing the bending rigidity of the vertical stiffeners and the thickness of the corrugated steel plates, as well as reducing the aspect ratio of the corrugated steel plates, is beneficial for enhancing the load-carrying capacity, stiffness, and energy dissipation capacity of the SCSPSWs. Finally, the transition rigidity ratio μ0,h was proposed to describe the hysteretic performances. When the rigidity ratio is μ = 50, dissipated energy values of the SCSPSW could achieve 95% of the corresponding maximum dissipated energy. In engineering practice, hence, it is recommended to use stiffeners with a rigidity ratio of μ ≥ μ0,h = 50 to ensure desirable energy-dissipating capacity in the SCSPSW. Full article

The local buckling of I-section beams is investigated with the flange–web interactions taken into account. Using numerical results employing the finite element method and a semi-analytical method, the flange–web interactions of I-sections and their effects on the buckling stresses are explored and discussed. Simple approximate solutions for the buckling coefficients of the web and compressive flange are developed using the energy method, and they are refined using the numerical results. Using the simple solutions for buckling coefficients, the limits for the width-to-thickness ratio of the compressive flange and web of I-section beams are then proposed. Comparisons with the results of existing solutions and provisions in design codes imply that the proposed solutions are superior in predicting the limits for width-to-thickness ratios, and they are capable of accounting for the flange–web interactions at the local buckling of I-section beams.

A new type of non-dismantling composite insulation panel, namely a steel-wire-enhanced insulation panel, was proposed. Compared to traditional organic insulation panels, the construction procedure is reduced, and the fire resistance is improved. The flexural performance was explored experimentally and numerically to evaluate its ability to withstand lateral pressure when it was used as the formwork of a cast-in-place concrete wall. First, 6 groups of 12 specimens of steel-wire-enhanced insulation panels were conducted under 2 loading modes: 3-point bending loading and 4-point bending loading. The failure modes of these specimens included a straight crack at the bottom of the panel and the yielding of steel wire. The test results showed that the maximum bending moment of the specimens with an 80 mm thickness could reach 2.415 kN·m. Second, finite element (FE) models were developed for the steel-wire-enhanced insulation panels by ABAQUS, which were validated by the experimental results. Third, a parametric study with parameters, including the thermal insulation cover, the square gird spacing of the steel wire mesh, and the diameter of the steel wire, was performed. It was observed that the insulation cover had a significant effect on the flexural capacity in the simulated range. Finally, theoretical formulas for panel stiffness and flexural capacity were presented, which can predict the bending performance more conservatively compared to the experimental results. The research and analysis of this study could offer a valuable reference for designing this panel in practical applications. Full article

The steel racks on the floor are seen as live loads in the current design process, ignoring the interaction with the supporting frames. In this paper, multiple steel racks with different masses and stiffnesses are placed on the first floor of a two-story main structure to form different real structures (RS). The corresponding simplified structures (SS) are frames with the mass of steel racks concentrated on the first floor of the main structure. Modal analysis is performed to analyze the relationship between the periods of RS and SS in the cross-aisle direction. Firstly, the beams on the first floor are assumed to be infinitely rigid. The relationship between the periods of the rack TRk, the simplified structure TSS, and the real structure TRS under different mass ratios α is established, and an accurate equation relating TRS with TRk and TSS is proposed. Moreover, by considering the influence of finite beam stiffness, the interaction between racks and the main structure is studied by constructing different analysis models. The effect of the main structure on the racks is reflected by a combined system consisting of beams and racks. A modified model, distinguished from SS by considering the effect of no-mass racks, is constructed to study the strengthening effect of the racks on the first-floor beams. The effect of the top connecting bars is also analyzed. Full article
