Pull-out behavior evaluation of torque-controlled expansion anchors under various installation conditions of concrete

Torque-controlled expansion anchors are widely used as anchoring elements in heavy nonstructural elements. Although the installed torque is not considered a design parameter for determination of anchor strength, it can affect the contact condition between the concrete and anchor as well as the failu...
