Design Recommendations for Concrete Pryout Capacity of Headed Steel Studs and Post-Installed Anchors

چکیده

Current formulas to assess the shear capacity of headed steel stud anchors and post-installed (PI) in case pryout failure (sometimes known as pull-rear failure) have been derived either based on indirect-tension resistance model or are fully empirical push-out test results. In both cases, predicted is clearly conservative underestimates true anchorages, especially for stiff with low embedment-to-diameter ratios (hef/d < 4.5). This paper proposes an a semi-empirical formula predict concrete studs PI anchors. They were improved which accounts diameter spacing group Furthermore, database 214 monotonic tests from literature, including own (push-off horizontally tests), reevaluated compared provisions EN1992-4. The scope this assessment proposal includes single attached plate well connectors composite structures without metal deck embedded normal-weight concrete.

Behavior of Steel–Concrete Composite Beams with Corroded Shear Studs Under Negative Bending Moment

The behavior of corroded steel–concrete composite beams under hogging moment was studied by experimental investigation and theoretical analysis. A total of eight specimens, six of which had corroded shear studs, were tested. The corrosion rate of studs ranged from 0 to approximately 50%. The constant-current accelerated corrosion method was adopted to accelerate the corrosion process. The loadi...

Stepwise Regression for shear capacity assessment of steel fiber reinforced concrete beams

The addition of steel fibers into concrete improves the postcracking tensile strength of hardened concrete and hence significantly enhances the shear strength of reinforced concrete reinforced concrete beams. However, developing an accurate model for predicting the shear strength of steel fiber reinforced concrete (SFRC) beams is a challenging task as there are several parameters such as the co...
