ABSTRACT:

This paper presents an experimental investigation, dealing with mechanical property on a newly developed split tee type WF beam-to-RHS column connection using both plug and fillet welds in steel moment resisting frame.   Initially, strength of plug weld subjected to tensile load has been evaluated from the test result of simple T-T joint experiment.   Next, experiment of subassemblage being welded split tee bracket to RHS column by means of plug weld and/or fillet weld has been conducted. And it has been shown that the proposed design formulae can predict fairly well the yield and ultimate strengths of the connection, after comparing with the experimental result.
