Zusammenfassung:PROBLEM TO BE SOLVED: To provide a capacity assessment method and a design method for a high-performance perforated steel plate dowel that can demonstrate required performance when exposed simultaneously to axial force, bending moment, and shear force.SOLUTION: An assessment method is for assessing capacity of a high-performance perforated steel plate dowel used for joining a member with concrete. The high-performance perforated steel plate dowel includes: a perforated steel plate comprising a steel plate protrusively provided on the member, is embedded in the concrete, and having one or a plurality of tiers of holes formed thereon; a penetrating reinforcement arranged to penetrate through the hole; a flange plate welded on a side of the perforated steel plate opposite a side fixed to the member; and a hoop reinforcement arranged around the perforated steel plate. Shear capacity V of the high-performance perforated steel plate dowel to withstand axial force is assessed (step S3) based on shear capacity Vpsud of the high-performance perforated steel plate dowel when assumed as not having the flange plate, and bearing yield strength Vfu of the flange plate (steps S1, S2).SELECTED DRAWING: Figure 2 【課題】軸力、曲げモーメント、せん断力の同時作用下において所要の性能を発揮可能な高性能孔あき鋼板ジベルの耐力評価方法および設計方法を提供する。【解決手段】部材とコンクリートとの結合を図るために使用される高性能孔あき鋼板ジベルの耐力を評価する方法であって、高性能孔あき鋼板ジベルは、部材に突設され、かつ、コンクリートに埋め込まれ、孔が一段または複数段に開けられた鋼板により構成される孔あき鋼板と、孔を貫通するように配置した貫通鉄筋と、孔あき鋼板の部材に固定される側とは反対側に溶接したフランジプレートと、孔あき鋼板の周囲に配置した帯鉄筋とを備えるものであり、フランジプレートを有しないと仮定した場合の高性能孔あき鋼板ジベルのせん断耐力Vpsudと、フランジプレートの支圧耐力Vfuとに基づいて(ステップS1、S2)、高性能孔あき鋼板ジベルの軸力に対するせん断耐力Vを評価する(ステップS3)。【選択図】図2
