This paper deal with the experimental and theoretical study of the rigid frames with triangular stiffeners located in the plane of the beam franges. The purposes of the paper are to certify the applicability of the author's formulas (see ref. 18), 19), 20)) to the connections under lateral force and to survey the effects that the deformation of the beam flange connections and panel zone have on the elasto-plastic behavior of the structures. Theoretical analysis of the structures took into consideration the deformation of the beam, column, beam flange connection and panel zone as well as the P-Δ effect of the column. The conclusions from the study are as follows; I) the analytical results simulated very well the elasto-plastic behavior of specimens. II) the author's formulas to determine the strength and the deformation of the beam flange connection in the elasto-plastic range are applicable for structures under lateral force. III) the rigidity of the panel zone in the plastic range is about 4% of the one in the elastic range. IV) the deflection of the actual structure is considerably greater than the structure with ideally rigid connections. V) the deflection caused by the deformation of the beam flange connection is nearly equal to the deflection caused by the panel zone in practice. VI) P-Δ effect affects the deflection after yielding of the structure and also the ultimate strength.
