CORNER PART STRUCTURE OF REINFORCEMENT BAR CONCRETE STRUCTURE
To secure proof strength of a corner part while avoiding an excessively concentrated arrangement of a reinforcement bar inside of the corner part.SOLUTION: A structure of a corner part in a reinforcement bar concrete structure is provided and is characterized in that the corner part is constructed by a steel fiber reinforcement concrete, more preferably by a steel fiber reinforcement concrete having a better tension softening property than a concrete used in a configuration member adjacent to the corner part. The tension softening property is preferably that a maximum value of the tension stress after an occurrence of a crack is greater than 2.0 N/mm2.SELECTED DRAWING: Figure 1
【課題】隅角部の内部において鉄筋の過密配置を回避しつつ、隅角部の耐力を確保すること。【解決手段】鉄筋コンクリート構造物における隅角部の構造であって、前記隅角部を、鋼繊維補強コンクリート、より好ましくは該隅角部に隣接する構成部材で用いるコンクリートよりも引張軟化特性に優れる鋼繊維補強コンクリートで構築したことを特徴とする。前記引張軟化特性は、ひび割れ発生後の引張応力の最大値が２．０Ｎ／ｍｍ２以上であることが好ましい。【選択図】図１
