Abstract

The main objective of this investigation was to study the shear behavior of interior beam-to-column connections in steel reinforced concrete frames subjected to monotonic loading.Six specimens which were designed so as to prevent flexural and shear failure of beam andcolumn members were tested, whose connection panels were made of pure steel, pure concrete orsteel-and-concrete. The effects of the ratio of beam width to column width on the behavior ofconnections were investigated.The test results showed that the shear strength of interior connection was considerably largerthan that of exterior and corner connection which was previously conducted by authors and theshear strength increases with the increase of the ratio of beam width to column width. From thetest results, the empirical equation for the shear strength of beam-to-column connections wassuggested.
