摘要： PROBLEM TO BE SOLVED: To provide an end structure of a reinforcement used in a reinforced concrete structure, which can be machined by using miniaturized manufacturing equipment on a building site etc., and which can cause a fracture in a base material of the reinforcement by avoiding a screw portion from becoming a weak point, and an anchoring structure.
SOLUTION: A tapered screw portion 30 is formed by applying cutting work to an end of the reinforcement 10 as an anchoring portion in a tapered shape after plastically hardening the end. Preferably, the plastic hardening treatment of the end of the reinforcement 10 is applied only to a base end part of the tapered screw portion 30. The anchoring structure is made by combining the reinforcement 10 constituted as above and a nut screwed to the tapered screw portion 30.

摘要： PROBLEM TO BE SOLVED: To improve the plastic deformation performance of reinforced concrete members by expanding plastic hinge regions P1-3. SOLUTION: In the reinforced concrete member which is subjected to bending forces when external forces are applied, yield bending proof stress R1 is changed over a predetermined range in the axial direction. The distribution of this yield bending proof stress R1 is adjusted to the distribution of the bending moment Mr1 generated when the reinforced concrete member begins to have bending yield. The reinforced concrete member will evenly yield and be plasticized over the predetermined range when it is bent and causes the bending moment beyond the yield bending proof stress R1 (e.g., the bending moment Mu1 at final time). And the energy of external forces applied is absorbed during the process when the reinforced concrete member is plasticized over the predetermined range (i.e., the plastic hinge range P1) and reaches the final conditions.

摘要翻译：要解决的问题：通过扩大塑料铰链区域P1-3来提高钢筋混凝土构件的塑性变形性能。解决方案：在施加外力时受到弯曲力的钢筋混凝土构件中，屈服弯曲应力R1在轴向上改变预定范围。该屈服弯曲应力R1的分布被调整为当钢筋混凝土构件开始弯曲屈服时产生的弯矩Mr1的分布。当钢筋混凝土构件弯曲时，钢筋混凝土构件将在预定范围内均匀地产生并塑化，并使弯矩超过屈服弯曲应力R1（例如最终时刻的弯矩Mu1）。并且当钢筋混凝土构件在预定范围（即，塑性铰链范围P1）上塑化并且达到最终条件时，施加的外力的能量在该过程期间被吸收。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a power transmission steel tower foundation using a small anchor material, facilitating construction and structural design of the steel tower foundation, and reducing the foundation.
SOLUTION: In this power transmission steel tower foundation, anchor materials 4 are radially projected through a mounting plate in the periphery of a leg material supporting the steel tower, and the leg material is buried in the foundation concrete. The tips of the anchor materials are disposed in the position near the edge part of the mounting plate 3 and reduced in size, whereby the anchor materials can be disposed inside a reinforcement cage such as a pile main reinforcement to prevent increase in width of the foundation floor system and width of a site. Thus, the earth work amount can be reduced. Further, the reduction of size can facilitate arrangement of reinforcement inside the concrete floor system and installation work for the leg material, and improve executability of work.

摘要： PROBLEM TO BE SOLVED: To provide a very economical tower foundation having sufficient loading capacity to achieve excellent safety. SOLUTION: This tower foundation is designed by applying the conditional expression based on the thin-walled cylinder theory. This conditional expression defines that the anchoring force P 0 against pulling-out of a reinforcing bar in the axial direction (an outer peripheral reinforcing bar 70) exceeds the force P 1 in the direction of pulling-out of the reinforcing bar in the axial direction. The anchoring force P 0 against pulling-out of the reinforcing bar in the axial direction is the sum of a value (anchoring force of a concrete part) obtained by dividing the product of thickness c of covering concrete in a structure of a thin-walled cylinder, tensile strength f t of the concrete, and length L of anchored reinforcing bar in the axial direction by tan θ and a value (anchoring force of a hoop) obtained by dividing the product of the number of steps N w of the hoop in the structure of the thin-walled cylinder, cross sectional area A sw of the hoop, and yield strength f swy of the hoop by tanθ. The force P 1 in the direction of pulling-out of the reinforcing bar in the axial direction is 1/2 of the product of the number N s of the reinforcing bars in the axial direction, cross sectional area A s of the reinforcing bar in the axial direction, and yield strength f y of the reinforcing bar in the axial direction.
