PROBLEM TO BE SOLVED: To make a tendon exhibit a reinforcement effect to punching fracture so as to contribute to easing of inclusion of a shearing reinforcement material in a flat slab structure having a flat slab supported by a column. SOLUTION: An unbonded tendon 3 is disposed around a column 1 so as to draw a curved line protruding toward a flat slab 2 in a view from the column 1 side. The tendon 3 is disposed around the column 1 to be vertically protruded up around the column 1 and protruded down in the center of the flat slab 2 or the vicinity thereof. The tendon 3 is disposed so as to surround at least two side surfaces of the column 1. A plurality of tendons 3 is juxtaposed on each side of the side surfaces of the column 1 so as to be disposed in a curved line shape in a plane view. COPYRIGHT: (C)2009,JPO&INPIT
