Abstract

The type of contact surface has a significant impact on the frictional resistance. Experimental evaluation of the effect of contact surfaces on bolt connections has been conducted in current research. The purpose of this study is to study the effect of different levels of contact surface on the frictional resistance and propose a new method for increasing frictional resistance. Contact surfaces used in this research are as follow: non sand-blasted, sand-blasted, coating with 20 μ thickness, coating with 40 μ thickness, triangular corrugated surface and squared corrugated surface. The results indicate that, the highest and the lowest bearing capacity were captured according to corrugated surface and 40 μ coated surface, respectively.
