要旨 1. INTRODUCTION
There are many studies attempting to find new types of structures which are suitable for conventional and new types of constructions. Among them the composite member with concrete sandwiched by steel plates is applied to slabs and offshore structures. There are advantages of this kind of composite member. It can endure large deformation and absorb a great deal of energy until the failure. For the same size of section, the composite member can obtain higher strength than conventional reinforced concrete. Buckling resistance of the steel component becomes greater than that in steel structure. Although there are many types of composite members, the rational design for shear and flexural resistances has not been established. In this study, shear resisting mechanism of the sandwich-composite member was investigated and especially stresses in shear span including web stress were discussed.
4. CONCLUSION
The truss mechanism was observed in the sandwich-composite member with web reinforcement. It can explain the stresses of steel and concrete in shear span in good agreement. The web spacing to effective depth ratio affects the truss mechanism for the member with tie plate but not for the member with diaphragm. The web stress is affected by the type of web reinforcement, width of type plate and shear span to effective depth ratio. Truss mechanism can also predict the deflection of member with good approximation.
