“…Shao et al [20] proposed a composite deck system composed of orthotropic steel deck, ultrathin UHPC layer and asphalt pavement. The relevant model experimental study and theoretical calculation were conducted on the behavior and fatigue performance of this composite OSD system [21][22][23][24][25]. The study results showed that the UHPC layer significantly enhanced the rigidity of the OSD system, reduced the stress level of steel deck plate and improved the mechanical behavior of asphalt pavement.…”

A novel ultra high performance concrete (UHPC) layer composite orthotropic steel deck was adopted in the construction of a new bridge in China to improve the fatigue performance of the orthotropic steel deck plate and reduce the disease of surface wearing layer. In situ experiments were conducted to study the UHPC layer’s impact on the behavior of the orthotropic steel deck. The test vehicle loads were applied on the deck plate before and after UHPC layer paving, the stresses where fatigue cracks usually occur and the deflections of critical sections were measured. The test results verified that the UHPC composite steel deck system could significantly reduce the stress of the rib-to-deck connection region and the stress at the bottom toe of rib-to-diaphragm weld. In addition, it slightly influenced the performance of U shape rib, girder web-to-deck and diaphragm cutout.

“…It has been employed in steel–concrete composite structures to enhance structural stiffness and reduce stress level under service vehicle loads in recent years. Afterward, it can significantly reduce the risk of fatigue cracking during the life cycle of such structure (Cao et al, 2017; Dieng et al, 2013; Pan et al, 2016; Wang et al, 2017).…”

“…Some researches have focused on studying the shear behavior of headed stud embedded in the UHPC slab. Cao et al (2017) investigated the static and fatigue behavior of short-headed studs with diameter of 13 mm embedded in a thin UHPC layer. The test results showed that shank failure caused the failure of specimens.…”

In this article, the static shear behavior of large-headed studs embedded in ultra-high-performance concrete was investigated by push-out test and numerical analysis. A total of nine push-out specimens with single and grouped studs embedded in ultra-high-performance concrete and normal strength concrete slabs were tested. In the testing process, only shank failure appeared without cracks occurring on the surface of ultra-high-performance concrete slab when the steel–ultra-high-performance concrete specimens reached ultimate shear capacity. The shear capacity of specimens with large studs embedded in ultra-high-performance concrete slab increased by 10.6% compared those in normal concrete, and the current design codes such as Eurocode4, AASHTO LFRD 2014, and GB50017-2003 all underestimate the shear capacity of such kind of steel–ultra-high-performance concrete composite structures according to experimental results. Numerical models were established using ABAQUS with introducing damage plasticity material model. The influence of stud diameter, concrete strength, thickness of clear cover, and spacing of studs on the static shear behavior was thoroughly investigated via parametric analysis. Based on the experimental and numerical analysis, the existence of wedge block and the decrease of axis force are beneficial for improving the shear capacity of stud shear connectors.

“…Extensive push-out tests on studs embedded in lightweight and normal weight concrete (Chinn, 1965; Davies, 1967; Ollgaard et al, 1971; Shim et al, 2004; Valente and Cruz, 2009; Wang, 2013; Xue et al, 2008, 2012) have shown that concrete properties have significant effects on the behavior of headed studs. In recent years, there is a rapid increase in the application of headed stud shear connectors in new types of concrete such as crumb rubber concrete (Han et al, 2015, 2017), high-performance concrete (HPC; Cao et al, 2017; Kim et al, 2015; Tian and Du, 2016), steel fiber–reinforced cementitious composites (SFRCCs; Luo et al, 2016). These types of concrete are not considered in current design codes such as Eurocode 4 (EN 1994-1-1, 2004) and China Code GB 50917-2013 (2013).…”

The deformation behavior of headed studs is an important issue in the design of steel and concrete composite structures. In recent years, there is a rapid increase in the application of headed stud shear connectors in new types of concrete such as crumb rubber concrete and ultrahigh-performance concrete. In this article, totally 154 monotonic push-out tests from the literature on experiments of headed stud in various types of concrete were gathered and evaluated with the aim to study the deformation behavior of headed studs. As a result of a careful analysis on the effects of stud diameter and concrete properties on the shear stiffness of studs through the historic database, a new equation for shear stiffness was proposed. The new formula is a reasonably good predictor and is suitable for studs with a diameter ranging from 10 to 30 mm in the concrete with cylinder compressive strength ranging from 22.0 to 200.0 MPa. New formula for the load-slip curve of headed stud which includes a parameter related to the shear stiffness was also proposed. It can give good prediction for the slip not only at low load level but also large load level.
