抄録: For weight saving, access and piping, many holes are made on plate structure such as a ship hull and as teel girder bridge. In addition to the existence of hole, the ultimate strength of plate is decreased by initial imperfections caused by the application of welding and gas cutting to fabricate it. And the collapsed failure of such a structure has not ceased to exist. In this report, the numerical analyses of perforated plates with initial deflection subjected to in-plane compression are carried by mentioned means in first report. The deforming behavier, extension of yielding region, collapsed load and collapsed mode on the plate with a hole are investigated. By the results of those analyses, the relations between ultimate strength and mode or value of initial deflection or hole diameter are clarified. Furthermore, the empirical formula on the ultimate strength of perforated plate with initial deflection are introduced for practical use.
