Chemical-Bonded Anchor Bolts versus Traditional J and T Anchor Bolts Used in Machine Foundations

Abstract
Heavy machinery that undergoes significant impact in its lifetime requires support and a system that can resist dynamic forces and the resulting vibrations. In this context, this technical paper reports a case study on a machine featuring hydraulic steel sheet shears and two hammers. The machine foundation of the hydraulic steel sheet shears was fixed to a concrete foundation using chemically bonded anchor bolts of a certain length and diameter. A short time after the machine had begun operating, shear failure of the anchor bolts occurred. These chemically bonded anchor bolts were then replaced with T-shaped anchor bolts of the same length and diameter, which functioned well. Two hammers were fixed in cast using J-shaped anchor bolts. The J- and T-shaped anchor bolts functioned well in the machine for over 10 years. From field studies and years of successful construction practices, traditional J- and T-shaped anchor bolts fixed with reinforcement of concrete foundations are recommended for fixing machines with impact loads and are superior to chemically bonded anchor bolts.
