Abstract

Anchors are needed to transmit the load to the concrete in strengthening the structure of a building. The anchor is installed in two ways, namely the cast in place method and the post installed method. In the post installed method, given Sika anchorfix-2 adhesive. The study was conducted to determine the type of failure that occurred, the pullout capacity of the anchor implanted on the hef 90 mm, and the average value of the adhesive strength (μ) of the M12 x 160 mm stud anchor on the T beam specimen measuring 390 x 270 x 300 mm as many as three samples. Each method of cast in place, post installed plain holes, and post installed screw holes using 32.30 MPa fc' concrete with pullout test. The results of the study, the type of failure that occurs is a breakout failure. The pulling capacity value obtained in the cast in place method is 14415.78 N, the plain hole post installed method is 77603.29 N, and the screw hole post installed method is 87377.25 N. The anchoring strength capacity of the plain hole post installed method is higher. greater than the cast in place method with an increase of 6.82%, the adhesive strength of the post installed method with threaded holes is greater than the cast in place method with an increase of 8.14%, and the adhesive strength of the post installed method of threaded holes is greater than the post installed method of holes plain with an increase of 1.24%.
