摘要： PROBLEM TO BE SOLVED: To improve cost efficiency and earthquake resistance by arranging hoops inside axial reinforcements across the root section within a specific range of a cross-section height. SOLUTION: Hoops 4 are arranged inside axial reinforcements 2 within the range of 0.5 to 1.5 times a cross-section height serving as the plastic hinge section of a concrete column 1 in case of an earthquake for restraining inner concrete. On the upper side of this section, hoops 3 are arranged outside the axial reinforcements 2 in the same way as a conventional one to prevent adhesive destruction of the axial reinforcements. Instead, hoops are arranged outside the axial reinforcements 2 and inside the axial reinforcements 2 of the plastic hinge section. Or, they are arranged so that the right and left facing surfaces of one hoop are placed outside the axial reinforcements 2 and the fore-and-aft facing sides of one hoop are arranged inside the axial reinforcements and those of the other hoop are arranged in a reverse way respectively. It is thus possible to improve deformation performance after flaking of covering concrete at the time of an alternate loading action if an earthquake occurs, thereby reducing the number of hoop and downsizing the cross section of the member.

摘要： PROBLEM TO BE SOLVED: To work without being affected by working environment and increase workability by connecting a recessed joint and a protruded joint to members to be connected beforehand, opposing the recessed joint and protruded joint to each other at site, and pressing or inserting them by using a spring action. SOLUTION: Those steel plates 2 to which a recessed joint 10 and a protruded joint 20 are connected beforehand are opposed to each other by a working vehicle such as a crane at site so that they surround a pier, and the protruded joint 20 is inserted in parallel with the axial direction of the joint through the opening of the recessed joint 10. Also the opening is expanded by the spring action of the recessed joint 10, and the protruded joint 20 is inserted. When the protruded joint 20 is inserted completely into the recessed joint 10, the opening is recovered by the spring action. By this, the hooking protruded parts 10a and 10b of the recessed joint 10 are hooked to the extended protruded parts 20a and 20b of the protruded joint 20 and, therefore, even if a parting force acts on them, they will not be extracted completely. Thus working can be performed without being affected by working environment, and the workability can be increased.
