This paper describes structural behaviors of concrete filled rectangular tubular steel column, and H-beam subassemblages without diaphragms of the beam to column connection. Our previous studies showed that the load-deformation relationship of beam to column connection without the diaphragms had semi-rigid characteristics. In this paper, the structural behaviors of interior beam and column subassemblages and structural elements such as beam, column, joint panel, related to semi-rigid characteristics of the connection were mainly investigated based on the experimental results. The followings can be concluded from the study: (1) The relationships between story shear and story drift of interior beam and column subassemblages were predicted by the value summed up the calculated load - displacement relationships of beams, columns, joint panel and beam to column connections without diaphragms. (2) Load - deformation relationships of joint panels were modeled by considering the stress condition of steel web in joint panel and in-filled concrete affected by the local deformation of beam to column connection.
