The purpose of the present paper is to show how to estimate an elastic-plastic behavior of to-RHS column connection without diaphragm. The elastic-plastic behavior o such connection is regarded as not rigid, but semi-rigid, because out-of-plane deformation in column flange cannot be neglected; the behavior of the connection is analytically model as non-linear rotational spring at beam-ends. In this paper, properties of the rotational spring, tangent s ' ess and maximum strength, are determined by numerical analysis based on yield line theory d finite element analysis, and estimating equations for the properties are proposed. The connection with horizontal haunch at beam flange and the one partially thickened at column flange are also considered.
