Summary: Full-scale push-out tests were conducted to study the shear behavior of HSBCs in prefabricated steel-concrete composite bridge beams. The tests considered key parameters including steel block height, longitudinal connector spacing, presence of oblique rebars in the precast slab, and grouting material. The results showed that HSBCs have large shear stiffness, high shear capacity (approximate to 1500kN), and sufficient deformability. The height and spacing of HSBCs were identified as the two principal parameters affecting shear capacity and failure mode.

Summary: Bending tests were conducted on steel-concrete-steel (SCS) sandwich panels with headed studs to investigate their mechanical behavior. The effects of loading mode, steel plate thickness, concrete core thickness, and connectors spacing were considered. The research results were validated using finite element model (FEM) and further studies were conducted to analyze the load-bearing capacity and shear resistance of the sandwich structure. The findings will have an impact on predicting the large deformation and ultimate strength of sandwich protective panels.

Summary: This study investigates the pry-out failure of single headed stud anchors after fire exposure using experimental and numerical methods. The research shows that the load-bearing behavior of anchors is influenced by concrete compressive strength, embedment depth, and fire duration. The numerical simulations successfully predict the pry-out failure mode and load bearing behavior of anchors after fire exposure, indicating a need for improvement in current design formulas.

Summary: Space trusses are used as three-dimensional frames in industrial structures, providing greater span capabilities. The weight and stiffness-to-weight ratio of a space truss structure are advantageous. The concrete slab over the upper chords of the space trusses helps overcome buckling issues, and the composite action between the slab and truss is crucial for load support.

Summary: This study proposes the use of grouted stud connectors (GSC) in steel-timber composite (STC) systems and explores their mechanical characteristics through finite element modeling. The results show that stud diameter, angle, and strength have significant influences on the shear capacity and stiffness of GSC connections. Additionally, a comparison is made between the finite element simulated results and predictions from design codes and literature. The study also discusses the group effect of GSC connections with multiple rows of studs and proposes an effective row number to characterize this effect.

Summary: The shear behavior of grouped stud connectors embedded in ultra high-performance concrete was studied through push-out tests with varied parameters. Results showed that increasing stud diameter improved shear performance, while reducing stud spacing could lead to a decline in shear capacity. Moreover, lower aspect ratio was found feasible for thinner UHPC slabs.

Summary: This paper studies the influence of headed studs as connectors on the mechanical properties of steel-UHPC composite slab. Through tensile testing, the failure mode, loading process, bearing capacity, and stiffness were analyzed. The study focused on the commonly used studs with a diameter of 13 mm in steel-UHPC composite structures, with the parameters of steel fiber content (0%, 1%, and 2%) and specimen size (160 mm and 200 mm) being considered. The impact of each parameter on the tensile load-interface separation curve, failure mode, tensile bearing capacity, and tensile stiffness was analyzed.

Summary: This study investigates the effects of stud degradation and stud arrangement on the fatigue behavior of steel-UHPC composite decks through finite element analysis. A numerical method considering stud degradation is proposed and experimentally validated to evaluate the fatigue performance of composite decks. Parametric analysis is conducted to study the effect of stud arrangement. The results show that stud degradation and reduced stud spacing result in a more uniform distribution of shear forces at steel-UHPC interfaces. Neglecting stud degradation may underestimate the fatigue life of stud connectors. This study advances the understanding of fatigue behavior and the ability to analyze fatigue in steel-UHPC composite decks.

Summary: This study investigated the shear capacity of solid-web H-shaped steel reinforced concrete (HSRC) columns under combined torque. Seven HSRC columns were tested, and the influence of different parameters on the shear capacity was analyzed. The results showed that the addition of H-shaped steel improved the shear capacity, while increasing the axial compression ratio increased the shear capacity. However, increasing the torsion bend ratio and shear span ratio decreased the shear capacity.

Summary: This study aims to reveal the mechanisms that determine the survival of suspended domes when subjected to sudden cable rupture. The results show that the remaining structure can arrest the initial local damage and establish an alternative path for hoop cables, thereby regaining balance. The relaxation of hoop cables can transmit outwards and inwards, causing severe damage and potential structural collapse. The failure of diagonal cables has minimal impact on the structure.

Summary: Structures susceptible to soft story mechanisms are particularly vulnerable to earthquakes. The strongback has been proposed as a way to prevent soft story mechanisms, but its impact on structural performance considering vertical stiffness irregularities and different arrangements of energy dissipation devices is unclear. This study investigates the effects of strongback on a small-scale four-story elastic structure with varying stiffness irregularities and damper arrangements. The results show that the strongback significantly reduces maximum story drift and makes the structural performance insensitive to damper position and distribution.

Summary: In this study, different weld details were proposed to improve the seismic performance of steel column splicing flange joints. Four full-scale specimens were tested under cyclic loads to analyze the hysteresis behaviors, yield moment, ductility, bolt forces, energy dissipation, stress and strains. Parametric analysis was conducted to discuss the influences of weld details, weld geometries, and flange openings. The results showed that different weld details had advantages in terms of ductility or energy dissipation capacity, bolt tension distribution, stress or strain distributions. Formulas for yield moments were proposed and validated for seismic design of bolted flange joints in prefabricated steel structures.

Summary: In this study, the post-fire performance of round-ended recycled aggregate concrete-filled steel tubular (RE-RACFST) short columns was investigated through experiments and numerical simulations. The results showed that an increase in the recycled aggregate content led to a decrease in the bearing capacity and elastic stiffness of the RE-RACFSTs, as well as an earlier onset of the confining effect. Finite element models were also established and used to study the effects of key factors on the residual load-carrying capacity. Furthermore, a simplified formula was proposed to estimate the post-fire residual capacity of RERACFST stub columns.
