Abstract
The reduction of slip strength of the multi HSFG (high-strength friction grip) bolted joints in tension is empirically known. In this study, the elasto-plastic finite displacement analysis for multi HSFG bolted joints is conducted. The analytical parameters of this study are considered the bolt row number, the bolt interval and the ratio of the design slip strength to the design yield strength, respectively. The variation of the slip strength to aforementioned parameters and the mechanism of the slip strength reduction are considered in this study. Furthermore, it does the investigation of extent of joint required to the slip strength reduction and the proposal of the strength reduction coefficient.
