| 要旨 | INTRODUCTION A large number of structures such as nuclear power reactors,offshore structures and barges can be constructed using concrete. The occurrence of an accidental impact to such structures of significant importance is very rare but nevertheless,precautions are necessary. The ultimate behaviour of structures is of much importance when studying these cases. In this study,slabs consisting of two materials were subjected to impulsive loads to verify the applicability of the layered finite element method. Also,an evaluation method on impact resistance for different materials was considered with the possibility of application to desi9n in future. CONCLUSIONS The results from this study can be summed up as follows:(1)The layered finite element method can simulate results obtained from experiments to a good degree of accuracy. Besides that,this method is applicable to slabs with different layers of materials.(2)An evaluation on impact resistance for slabs can be carried out based on impact load at failure,deflection at failure and also total energy.(3)Addition of steel fibre is efficient in impact resisting structures,It causes an increase in ductility in slabs. Besides that,flexural failure can be anticipated instead of punching shear. Partial addition of steel fibre in the rear face can also change the failure mode and improve impact resisting performance. |
