Abstract

PURPOSE:To improve reflecting performance and mechanical performance, by forming the reflecting body of a wave absorbing structure section in a wave absorbing wall structure, with steel-fiber-reinforced concrete or carbon-fiber- reinforced concrete. CONSTITUTION:In a wave absorbing wall structure with a wave absorbing structure section A laminated on a reinforced concrete structural-frame B, the reflecting body 13 of the wave absorbing structure section A is formed with steel-fiber-reinforced concrete or carbon-fiber-reinforced concrete. The steel-fiber-reinforced concrete or carbon-fiber-reinforced concrete is excellent in electromagnetic reflecting performance and mechanical performance, and so this is used for both the structural body concrete and the reflecting body 13. As a result, the thickness of the wall is reduced and the weight of the wall is reduced, and the area of a structure can be effectively used, and the burden of a building foundation structure can be reduced.
