Abstract

High Tension Bolts (HTB) are known to exert a significant influence on connection strength characteristics and have and influence ductility of the joint. Normally failure occurs in shape resultant high stress concentration neck and threads areas, resulting in low ductility characteristics. In this research by waisting the HTB shaft such that failure occurs in the waisted shaft we investigated the stress concentration decrease in neck and thread regions and the ductility increase by finite element analysis and static tensile experimental tests. The improvement of bolt shaft tension loss was also examined
