Strength and durability of adhesive anchor bolts

الملخص EN

This paper presents results of a study on adhesive anchor bolts exposed to varying and diverse environmental conditions.

Pull-out tests were performed on standard concrete cylinders anchored with adhesive bolts.

The anchor bolts were placed either vertically or horizontally in the concrete cylinders.

Concrete cylinders were stored in their respective positions and exposed to various diverse environmental conditions.

The environmental exposure and anchor placement position effects on anchor bolt load carrying capacity and slip were evaluated.

Generally, the pull-out load for vertically placed anchors were higher than those for horizontally placed anchors.

Specimens stored under water and exposed to freezing and thawing cycles showed the lowest pull-out resistance.

In addition, the amount of slip at failure pull-out load was more for vertically placed anchors.
