Abstract
Nowadays the most common steel structural anchorage systems used embed anchoring elements. In recent years however, bonded steel anchors, i.e., elements that are post installed in concrete, have been increasingly used. This system of anchoring is used both in the redevelopment design of existing structures and in the design of new building structure. The main objective of this paper is to study the tensile behavior of adhesive bonded anchors when subjected to static tensile loading, also the effect of embedment depth, anchor diameter and the type of adhesive material used in anchor pullout load bearing capacity, failure mode and load displacement curve behavior. A total of 108 pullout baseline tests were tested in direct tension, divided into four groups, according to the types of adhesive material used, including three groups used cement-based mortar as adhesive material with different compressive strength and the last group used epoxy adhesive material (Sikadure-31). Each group divided into nine group that express three different embedment anchor depth and anchor diameter. Anchor diameter used was 10, 12 and 16mm, while anchor embedment depth used is related to the anchor diameter which is 6d, 9d and 12d, also additional 54 verification test for analytical purposes divided into three group, according to the types of adhesive material used, including two groups used cement-based mortar as adhesive material with different compressive strength and the last group used epoxy adhesive material (Sikadure-31). Results of investigation show three typical failure modes: pullout (bond) failure, steel yield and combined cone-bond failure, also showing that cement-based mortar can be used as adhesive bonding material, which is give a good tensile anchorage result compared to the
tensile result of anchorage when using the traditional epoxy material.
