Special Issue Information

Dear Colleagues,

It is our pleasure to announce this Special Issue of Buildings, which will focus on novel theories and technologies with respect to steel–concrete composite structural systems.

The steel–concrete composite structural system has the advantages of the fast construction speed of a steel structure, and the large rigidity and low cost of concrete structures, which have been widely used in high-rise and super-high-rise building structures, large-span bridges, wind power facilities and other infrastructure projects. At present, research on steel–concrete composite structures mainly focuses on the component and joint levels, and a large amount of experimental data have been accumulated for commonly used composite beams, composite columns and composite joins; in addition, relatively complete design theories and methods have been established. However, research on component integration and system optimization at the system level is still in its infancy, which lags behind engineering practice.

Novel and innovative strategies for the efficient design and rapid construction of steel–concrete composite structural systems are urgently needed. This Special Issue aims to provide selected contributions to advances in the design, construction, simulation, and maintenance of steel–concrete composite structural systems in diverse areas and countries.

Potential topics include, but are not limited to, the following:

  • Experimental study of steel–concrete composite structural systems;
  • Structural modelling and analysis methods of steel–concrete composite structural systems;
  • Prefabrication and automated construction of steel–concrete composite structural systems;
  • Behaviour and design of steel–concrete composite structural systems under various disasters;
  • Applications of advanced materials in steel–concrete composite structural members or systems;
  • Matching and optimization of various components in steel–concrete composite structural systems.

The present study was conducted to clarify the flexural behaviors of the Composite Girders of a Prestressed Segmental Ultra-High-Performance Concrete (UHPC) Channel and a Reinforced Conventional Concrete Deck (PSUC-RCCD). The girders can be used as bridge superstructures with the advantages of structural efficiency, cost-effectiveness, and easy construction. A total of five specimens were tested. Three of them were PSUC-RCCD specimens, including two semi-segmental girders (the channel beams were composed of five segments with dry-joints) and one integral girder (the channel beams were integral ones without dry-joints). The two other specimens were P-UHPC girders composed of PSUC and UHPC deck slabs; one was semi-segmental and the other was integral. The flexural behaviors of the specimens were investigated, including the load-displacement curves, crack distribution, cracking moments, and ultimate flexural capacity. The study compared the influence of the segment number and deck material on the flexural behaviors of semi-segmental girders and introduced and validated methods for calculating the cracking moment and flexural capacity of both semi-segmental and integral sections in PSUC-RCCD and P-UHPC girders. The results show that the entire loading process of all the specimens can be classified into the elastic phase, the cracks development phase, and the failure phase. Compared to the integral girders, the number of segments has little effect on the flexural behavior of the semi-segmental girders, but it has a significant effect on the cracking moments. The cracking moments of the semi-segmental girders is only 0.58~0.60 of the integral girders. Reducing the strength of the deck slab by changing the material from UHPC to CC does not significantly affect their flexural behaviors. Based on the test results, this work proposes a method for predicting the cracking moment and flexural capacity of the semi-segmental girders, the results of which fit well with the test results, and it is applicable in the structural design of such members.

If a bridge is subjected to a blast load when there is vehicle traffic, not only its own safety is threatened, but it can also lead to damage to vehicles. In addition, the coupling of a vehicle load and an explosion load may further aggravate the impact of an explosion. To understand the coupling relationship between the two kinds of loads on a bridge, a static load was applied on the bridge using the impact coefficient while a blast load was applied on the outside of the bridge. A numerical simulation was also used to further study the coupling effect of the vehicle load and the explosion load. The results showed that the vehicle load could effectively limit the vertical deformation. The numerical model was accurate in predicting the response process of the stiffened beam. With the coupling of the vehicle load, the equivalent plastic strain of the box multistage stiffened beam was mainly concentrated at the hinge and decreased when the blast loading remained constant. The transverse anti-blast performance of the stiffened beam was mainly provided by the bridge web and the diaphragm under the coupling effect of the vehicle load and the blasting load, but the function of the diaphragm was weakened. Additionally, the hinge used as a connector was able to directly affect the bearing capacity of the bridge. Even if the hinge was only slightly damaged, it could cause the bridge to enter the failure stage, meaning that the strength of the hinge must be greater than that of the bridge. Full article
