The shell & bulkheads of ships in general are made of flat plates which are reinforced by vertical & horizontal stiffeners, and these stiffeners are connected by large quantity of angles, face plates and brackets, for which a great number of labours are required.
The new construction which is called “Corrugated Plates Construction” is consisted of corrugated plates which have stiffness themselves and remarkably decreased stiffeners instead of flat plates and numerous stiffeners.
In this construction, we can reduce a great number of steel members and labours, and accordingly build ships, simpler in construction, lighter in weight and more reduced in price than that of flat plate construction.
The author has tried an experiment entitled “Strength of Corrugated Steel Plates ” to acquire the standards & data for applying this corrugated plate to practical shipbuilding.
This work deals with the instruction of the experimental model, its method and comparison of actually measured values with the approximately calculated values in regard to deflection of model plate.
As the result, we have known that there is not so difference in applying Beam Theory to the corrugated plates.
In this construction, it is proved, that the weight is reduced by 30% in comparison with the flat plate construction as required by rule.
