VERTICALLY SUSPENDED SHEAR REINFORCEMENT OF A COLUMN-SLAB JOINT CAPABLE OF PREVENTING SHEAR REINFORCEMENT BARS FROM SHAKING

摘要

PURPOSE: A vertically suspended shear reinforcement of a column-slab joint is provided to improve structural stability by increasing resistance to shear fracture of a column-slab joint.;CONSTITUTION: A vertically suspended shear reinforcement(100) of a column-slab joint comprises first and second sub frames(20,40), a connection piece(60), first, second, third, and fourth reinforcement bars(24a,26a,44a,46a), and a fastener(70). The first sub frame is composed of a first shear reinforcement bar(22), a first upper head(24), and a first lower head(26). The second sub frame is composed of a second shear reinforcement bar(42), a second upper head(44), and a second lower head(46). The connection piece connects the first and second sub frames to each other. The first reinforcement bar is vertically extended from one end of the first upper head. The second reinforcement bar is vertically extended from one end of the second upper head. The third reinforcement bar is vertically extended from one end of the second upper head. The fourth reinforcement bar is vertically extended from one end of the second lower head. The fastener connects the first and second shear reinforcement bars to each other.;COPYRIGHT KIPO 2012
