<P>PROBLEM TO BE SOLVED: To provide a structure capable of positively yielding an unbounded area, absorbing seismic energy and then suppressing the residual deformation of the unbounded area (fixing force decline part). <P>SOLUTION: When external force acts on a column member 12 and a beam member 14, the column member 12 and the beam member 14 are relatively moved. When they are relatively moved, tensile force acting on a PC steel wire increases and the column member 12 and the beam member 14 are to be restored to an original state. Also, when they are relatively moved, a fixing force decline part 24 of a beam main reinforcement 48 where fixing force with a filler 34 is lowered is pulled, the fixing force decline part 24 is plastically deformed and energy from external force is absorbed. That is, restoration force generated by the tensile force acting on a connection member and energy absorption by the plastic deformation of the fixing force decline part 24 in the beam main reinforcement 48 act simultaneously. The fixing force decline part 24 is plastically deformed (yielded) positively, the seismic energy is absorbed, and then the residual deformation of the fixing force decline part 24 can be suppressed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
