The experimental results of the elasto-plastic and Collapse behavior of steel subassemblage with weak joint panel and with reinforced concrete floor slab on beam under seismic loading are discussed. The main purpose in this paper is to make the Collapse mode of steel frame clear in the relation of strength between joint panel and beam. The some conclusions herein are summarized as follows. (1) In the range α>0.7, defined as panel-beam yield strength ratio α, beam-Collapse mode appeared, (2) frame with smaller α values than around 0.4 became panelCollapse, (3) in 0.4< α<0.7, simultaneous Collapse both in panel and in beam was supposed.
