The whole loading process of two-way self supporting composite plate with a kind of simple piece was studied,meanwhile the composite plate was experimentally studied and compared with the experiment of the same size casting plate.Results indicated that the failure form of the composite plate is similar to the casting plate.Based on these researches and combined with the numerical simulation technology,two-way stress mechanism,crack developing and distribution,bond and slip and stress-transfer mechanism of the rebar in the piece were studied carefully for the type of composite plate.Failure mechanisms of the composite plate in many cases were systematically analyzed and many useful references were provided for this composite plate.
