Shear behavior of a strain hardening cementitious composites (SHCC)-Grooved steel composite deck

Flexural capacity of steel-UHTCC (ultra-high toughness cementitious composite) bridge deck considering different shear connection degrees

“…Traditionally, an OSBD consists of a thin steel deck plate, longitudinal U-ribs, and transverse diaphragms. OSBDs are generally covered by 35–80 mm thick asphalt overlays (Cao et al, 2016; Yin et al, 2019). However, with the increase of traffic volume and heavier vehicle wheel loads, welded joints of OSBDs are easily subjected to fatigue cracking (Aygül et al, 2012; Lukić and Cremona, 2001; Walter et al, 2007; Ya et al, 2011), which is mainly due to the insufficient stiffness of the steel deck plate (Miki, 2006; Teixeira De Freitas et al, 2017).…”

“…It should be noted that increasing the thickness of asphalt overlay has little impact on improving global stiffness (Xu et al, 2017; Yin et al, 2019). In order to enhance the stiffness, disperse traffic load, and improve the stress state of OSBDs, some researchers tried to replace asphalt overlay by rigid cement-based materials such as lightweight concrete (Li and Chen, 2011), reinforced high performance concrete (Peter et al, 2004), or traditional fiber-reinforced concrete (Abe et al, 2015; Dieng et al, 2013; Walter et al, 2007).…”

Mechanical Behavior of Strain-Hardening Cement-Based Composites (SHCC) Subjected to Torsional Loading and to Combined Torsional and Axial Loading

“…The remarkable crack control in SHCC leading to multiple cracking under tensile and compressive forces is responsible for the advantageous shear behavior of these composites [23]. In addition to some structural investigations on the performance of SHCC as main material [24] and for strengthening layers subject to shear [25,26], to date only a few investigations have been reported on the material characterization of SHCC under shear loading. Li et al [23] investigated the shear behavior of SHCC using Ohno shear beams [27].…”
