PROBLEM TO BE SOLVED: To provide a method of anchoring PC steels at a joint between a PCaPC column and a PCaPC beam, which solves a conventional problem of insufficient filling of concrete when the concrete is placed, and achieves improvement in reliability of a joint panel portion between the PCaPC column and the PCaPC beam, and increase in the bearing strength of the same, by forming the panel portion of ultra-high-strength concrete beforehand. SOLUTION: According to the structures of the PCaPC column and the PCaPC beam, a block 60 which constitutes a terminal anchor body of a PC steel of each of the beams 10, 20, and is formed of fiber-reinforced reactive powder concrete, is built in the column 30 as a core, and a tie hoop 35 is arranged only on the periphery of main reinforcements 33 of the column 30. Then an anchor body 40 of the PC steel, formed only of a bearing plate 42 and an anchor head 41 is inserted into the block 60 and anchored in the same. COPYRIGHT: (C)2004,JPO&NCIPI
