ANALYSIS OF INFLUENCING FACTORS FOR BEARING PERFORMANCE OF HIGH STRENGTH BOLTED CONNECTION IN STAINLESS STEEL WHICH CARRIED SHEAR FORCE

摘要

The application of stainless steel in buildings is a trend in civil engineering because of its corrosion resistance and good processing performance. However, there are few specifications or codes about stainless steel structure design in China, and the design theory and design method lags behind relatively. Stainless steel has obvious nonlinear performance, which should be considered of in the design. Cover plate connection is one of the bolted connections, which is an important form in steel structure. This paper analyzed the influencing factors for bearing performance of the bolted cover plate connection in stainless steel with finite element program ANSYS, and the values from tests and Euro code are compared. Also the effect of the factors for bearing strength of the bolt connection is discussed. Based on the results of the analysis, the bearing performance increased with the increase of the thickness of the plate, the diameter of the bolt and the end distance. When the bolt diameter and the end distance increase to some value, the effect reduces.
