Out of all the tension limit states required by ACI 318, concrete breakout is particularly important because a concrete failure would be non-ductile, and therefore it should be avoided. This blog post discusses how to calculate …

A cup and cone fracture is a type of failure observed in ductile metals and plastics that are subjected to a uniaxial force. It is essentially the separation of a body into two separate pieces due to the application of excessive tensile stress. This mode of fracture gets its name from the resulting shapes at the end of the broken pieces after a ...

Concrete Cone Failure occurs when the concrete surrounding an anchor fails, typically in a cone shape similar to the diagram below. This failure mode is applicable for Cast In, Mechanical Fasteners and Chemical Anchors.

failure; however, breakout failure modes for straight, group anchor assemblies are rarely considered. Breakout failure is a concrete tensile failure that typically results in cracking at a 35 o angle from the base of the anchor to produce a cone. This type of failure can significantly limit the pull-out strength of the system.

Combined concrete cone failure and anchor bolt pullout failure occurs when the bond between the grout or resin bonding agent and the concrete fails allowing the bolt and grout or resin to pull out from the concrete, taking a small cone of concrete as well. This failure mechanism is illustrated in the diagram below.

Bolt Tensile Failure: This occurs when the tensile strength of the bolt is exceeded, causing it to break or fracture under tension. Concrete Cone Failure: This occurs when the concrete surrounding an anchor fails, typically in a cone shape. Pullout Failure: In this mode, the fastener is pulled out of the concrete due to the tensile forces when ...

Three different effects control the influence of the loading rate on structural response: creep of bulk material, rate dependency of growing microcracks and structural inertia. The first effect is important only at extremely slow loading rates whereas the second and third effects dominate at higher loading rates. In the present paper, a rate sensitive model, which is based on the …

Concrete cylinders are often used in the construction industry to test the compressive strength of concrete. When a concrete cylinder is tested, it may break in one of several ways, which can provide important information about the properties of the concrete. Here are some common types of concrete cylinder breaks and what they can indicate:Type 1 (a). …

Tension concrete breakout assumes a failure forming a concrete cone based on a prism angle of 35 degrees. This method predicts the strength of a group of anchors by using a basic equation for a single anchor Nb, and multiplied by factors that account for the number of anchors, edge distance, spacing, eccentricity, etc. per ACI 17.6.2.
