Static behavior of grouped stud shear connectors in steel-precast UHPC composite structures containing thin full-depth slabs

Zhuangcheng Fang et al.

Summary: This study investigates the static analysis of grouped stud shear connectors in steel-precast UHPC composite structures through 18 push-out tests. The results indicate that the stud diameter and slab thickness play significant roles in the structural performance. Additionally, adopting appropriate shear pocket geometry improves the shear behavior of connectors. The grouped stud effect should be considered, and design recommendations are provided.

The effect of specimen size on autogenous and total shrinkage of ultra-high performance concrete (UHPC)

M. Sun et al.

Summary: This study experimentally investigates the shrinkage mechanism of low water to cement ratio concrete and finds a strong specimen size dependency in its shrinkage, which is different from normal strength concrete. Existing shrinkage models are not applicable to this type of concrete.

Steel-alkali activated cement based ultra-high performance concrete lightweight composite bridge decks: Flexural behavior

Weijie You et al.

Summary: The bending performance of a steel-AAUHPC lightweight composite deck was investigated and compared with a steel-UHPC lightweight composite deck. The results showed that increasing the thickness of concrete cover improved the bending performance, while increasing the reinforcement ratio enhanced the ductility of the composite deck. Furthermore, increasing the degree of shear connection improved the composite action.

A review and comparison study on drying shrinkage prediction between alkali-activated fly ash/slag and ordinary Portland cement

Dunwen Huang et al.

Summary: Alkali-activated binder (AAB) concrete is considered an environmentally friendly material with high strength and low carbon emissions, but its greater shrinkage compared to ordinary Portland cement (OPC) poses challenges for its engineering applications. Current research focuses on understanding the mechanisms and factors influencing AAB shrinkage, with limited predictive models available.

Flexural behavior of corrugated steel-UHPC composite bridge decks

Zhenyu Cheng et al.

Summary: This study established a finite element model to investigate the flexural behavior of composite bridge decks, which was validated against experimental results. The results showed that the MCL-shaped dowels provided sufficient shear strength, and the composite bridge decks exhibited flexural failure mode with adequate ductility.

Push-Out Behavior of Short Headed Stud Connectors in Steel-Ultra High Performance Concrete Composite Deck

Qiu Zhao et al.

Summary: The mechanical behavior of short studs in UHPC composite decks was investigated, revealing that a longer stud length may improve shear strength and larger diameters or lengths can increase shear stiffness of push-out specimens. Pull-out failure could occur when the stud length is less than 25 mm in UHPC, with the failure mode being affected by concrete strength.

Mechanical properties, shrinkage, and heat evolution of alkali activated fly ash concrete

Kitipong Ruengsillapanun et al.

Summary: Increasing the Na2SiO3/NaOH ratio and NaOH concentration can enhance the compressive strength of concrete. The modulus of elasticity of alkali-activated fly ash concrete was similar to that of conventional concrete, while concrete shrinkage tended to decrease with increasing NaOH concentration and increase with higher Na2SiO3/NaOH ratio.
