Numerical Analysis of the Influence of Head Diameter on the Breakout Capacity of Shallow Headed Studs

Popis výsledku v původním jazyce

The aim of this paper is comparison of 2D numerical analysis results of cast-in-place headed studs with different head size and effective embedment depth to the CCD (Concrete Capacity Design) approach that is used for design of anchoring in Eurocode 2. Breakout simulation tests of six different head diameters with four different effective embedment depths were investigated. The concrete properties were kept constant for all of them. It was found that the capacity of anchor is affected by the head size significantly. The approximately 25% decrease of capacity for small heads and about 30% capacity increase for large heads were observed in comparison to the CCD method.
