Ultimate Strength of a Steel/Concrete Cylindrical Open Sandwich Panel

摘要

Results from an experimental and FEM analysis of the composite steel concrete cylindrical shell structures of open sandwich system on ultimate strength are reported. In the experimental investi- gation, concentrated loading tests were conducted on open sandwich type composite cylindrical shell panels. From the experiments, it was clarified that the composite shell panel under concentrated loading showed the punching shear failure, but the composite panels exhibited the high load bearing capacity after the punching shear failure. In the FEM analysis, the deflection and stress distribution of the models were calculated.
