Abstract
The paper innovatively proposes a basic hypothesis based on classical formula: assuming that bolt groups unevenly distributed along the arc are a collection of individual bolts in a symmetric rectangular area, which helps efficiently and effectively accomplish stress analysis and strength check of bolt groups. This method avoids problems such as inaccurate calculation and a waste of time in finite element calculation due to difficulties in handling boundary conditions, inaccurate contact type, and continues to adopt the calculation method of classical formula to simplify difficult issues and ensure that the calculation results can be applied in actual conditions of projects. Besides, it saves computing resource and shortens computing time. Thus, this research can guide engineering practices.关键词
