Shear Resistance Mechanism of Extremely Short Columns Constituted by Thin Steel Plates with Ribs and Fiber Sheets as Shear Reinforcement

リブ付きの薄肉鋼板と繊維シートをせん断補強材とする極短柱のせん断抵抗機構

The aim of this paper is to examine the shear resistant mechanism of RC (reinforced concrete) columns with an outer shell structure consisting of a divided thin steel plate with ribs and polyethylene fiber sheets when subjected to shear force. The steel plates do not require any welding on site. This paper mainly describes the shear effectiveness achieved through the use of ribs on steel plates in extremely short columns. The test results found that the shear resistance achieved through the elements of lateral ribs, web plates and polyethylene fiber sheets, is cumulative. Based on these results, the study indicates that shear capacity can be estimated by using the design guideline for ultimate shear strength issued by AIJ in 1990, which is based on the truss and arch model.本論文は，分割されたリブ付きの薄肉鋼板とポリエチレン繊維シートにより外殻構造を形成したRC造柱のせん断抵抗機構の検証を目的とし，そのせん断実験を実施したものである。ここでは，鋼板に設けたリブがせん断抵抗の向上に寄与しているか否かを調べることに着眼を置いており，極短柱とした試験体を取り上げている。実験検証の結果，せん断抵抗要素としては鋼板の横リブ部，鋼板ウェブ部並びにポリエチレン繊維シートに作用する引張力により構成されている旨が示唆された。そうした結果を踏まえて，本試験体のせん断耐力はトラス・アーチ機構の累加で説明された終局強度型耐震設計指針のせん断強度式を準用して評価できることを示した。
