Abstract

This work presents experimental investigation for analysis of shear lag and its effect in steel angle tension members with bolted connections. Seventy-two sets of specimens were fabricated to test for tensile load bearing capacity of angle sections.Twenty-six tests were performed on equal angle sections and forty-six on unequal angle sections with both two-bolt connection and three bolt connection. Different bolt arrangements in angle sections connected with their longer leg was considered for checking the difference in resulting strength. The test results indicated that variation in edge distance, end distance and pitch have influence in load bearing capacity of sections.Further clear mode of failure mechanism and load distribution was visualized with the help of finite element modelling. Results of previously published research were compared to find out the concurrent conclusions by other authors. The data analysis of results through finite element modelling and full-scale testing were utilized to account the effect of shear lag while other factors influencing block shear strength were varied.
