A series of tests were carried out to study the moment capacity of concrete filled S.H.S. column to concrete composited H-beam connections. Four types of connections were proposed and were tested. The main parameters for the test are filling of S.H.S. column with concrete and thickness of columns. Analytical estimation with COSMOS/M for initial stiffness, yield moment and moment capacity of the connections was made. Filling of S.H.S. column with concrete is found to play an important role for initial stiffness and strength and rotational restraint of the proposed connections.
