Abstract:
1. A joint connection in which a beam end and a column base of a structure, or a peripheral member rigidly joined thereto, are joined to another structure capable of receiving a bending moment via supporting means, wherein a deformation due to a very small geometric movement within a resilient range is generated in the supporting means by a reaction force generated at a joint portion with the other structure due to an external force exerted on a beam or a column, thereby being capable of generating a bending moment Mr in a reverse direction to a bending moment Mc generated in the column base or the beam end, wherein the supporting means is a combination of at least two rods, each rod having a lower end joined to a lower structure, an upper end coupled by a coupling member, and the coupling member joined to the column base or the peripheral member; and the upper ends and the lower ends of the rods being separated respectively, and an upper end interval being made narrower than a lower end interval, wherein the joint of the column base or the peripheral member and the coupling member is of a tensile joint where introduction tensile force is exerted therebetween, and wherein the tensile joint is provided with a resilient bridging member at the bottom of the coupling member, the resilient bridging member having both ends supported to the coupling member or the rods, the resilient bridging member having an intermediate portion which is separated from the coupling member to be a rational cross section with small deformation, and the intermediate portion of the resilient bridging member and the coupling member is passed through by a bolt which is joined to the column base or the peripheral member.
