Abstract
Provided is a reinforced concrete partitioning structure that can exhibit electromagnetic shield function against an electromagnetic wave at target frequency. It includes an RC wall to attenuate an electromagnetic wave at target frequency propagating from an inner space to an outer space, a concrete portion having a thickness in a direction from the inner space to the outer space, and a front reinforcing bar lattice which forms a reinforcing bar plane in lattice at a position along the thickness of the concrete portion. The front reinforcing bar lattice has a plurality of longitudinal bars arranged at fixed spacing, and a plurality of transverse bars arranged at fixed spacing to intersect the longitudinal bars. The spacings of the longitudinal bars and transverse bars are adjusted according to the wavelength of an electromagnetic wave at the target frequency.
