Abstract Details

2017, MS, University of Cincinnati, Engineering and Applied Science: Civil Engineering.
A large number of tests were performed on LeJeune Bolt Company’s TnA 144 high-strength structural bolt. The tensile and shear capacities of the TnA 144 were investigated as well as the effectiveness of the tightening method and hardness of the bolts. The TnA 144 has a minimum required tensile strength of 144 ksi and the tightening method combines torque and angle rotation that requires only a single operator For comparison, A325 and A490 grade bolts were also tested. A total of 1,759 structural bolts, consisting of three different grades and five different diameters, were tested. In conclusion, the tightening method consistently produced tension in the assembly above the required minimums for snug and final tension and had shear had tensile capacities consistent with the minimum required tensile strength of 144 ksi .
