摘要： PROBLEM TO BE SOLVED: To provide a construction method for a marine structure capable of improving productivity and workability. SOLUTION: A construction method for a pier 1 includes: an arrangement step in which a plurality of permanent forms 13 are arranged in the area excluding a beam forming area R on a base plate 11 of a precast panel 10; and an installation step in which concrete is placed on the beam forming area R that appears between the plurality of permanent forms 13 arranged on the base plate 11 and on the plurality of permanent forms 13 themselves, which comprises a beam 6 and a slab 7 joined to a plurality of pile heads 2a. In this way, a superstructure 3 having the beam 6 and the slab 7 is formed by preparing the plurality of permanent forms 13 and the precast panel 10, by arranging the plurality of permanent forms 13 on the base plate 11 of the precast panel 10, and by placing concrete on the base plate 11, which prevents from making and assembling a burial mould in a complex shape and improves productivity and workability.

摘要： PROBLEM TO BE SOLVED: To provide a plastic hinge structure of a concrete-based member, and the concrete-based member using the plastic hinge structure attaining the improvement of deforming performance and hysteresis damping characteristics of the concrete-based member in a civil engineering and building structure at a low cost. SOLUTION: The plastic hinge part 2 provided at the concrete-based member 1 of an RC member or a PC member is formed in a laminated structure A with rigid members 3 of plate shape and flexible members 4 of plate shape alternately arranged in the axial direction of the concrete-based member 1, and axial steel members 5 embedded in the concrete-based member 1 are inserted through the laminated structure A of the rigid members 3 and flexible members 4 to form an unbond section B in the plastic hinge part 2 and its vicinity. The rigid members 3 are provided with insertion holes 6 of the axial steel members to restrain the buckling deformation of the axial steel members 5 to thereby prevent buckling, and a shear deformation preventing member 7 for restraining the shear deformation of the laminated structure A of the rigid members 3 and flexible members 4 is provided in the laminated structure A.

摘要： PROBLEM TO BE SOLVED: To provide a truss composite floor slab which is easy for handling during storage or transportation or the like, and is ready for assembling after being carried in the site. SOLUTION: The truss composite floor slab includes a PCa floor slab 2 and a plurality of truss reinforcements 3 projected on the concrete construction joint surface 2a of the PCa floor slab 2. An embedding insert 4 is embedded in the concrete construction joint surface 2a of the PCa floor slab 2. The truss reinforcement 3 comprises an upper-end reinforcement 3a, a plurality of lower end reinforcements 3b, 3b and a plurality of lattice reinforcements 3c arranged between the upper-end reinforcement 3a and lower end reinforcements 3b, 3b, and formed into a three-dimensional truss form having substantially a triangle cross section. The lower end reinforcements 3b, 3b of the truss reinforcement 3 are attached to the concrete construction joint surface 2a of the PCa floor slab 2. The lower end reinforcements 3b, 3b of the truss reinforcement 3 are secured to the concrete construction joint surface 2a of the PCa floor slab 2 with a plurality of lower end reinforcement grasping tools 5 and fixing bolts 6. The fixing bolts 6 are screwed with the embedding inserts 4. COPYRIGHT: (C)2011,JPO&INPIT
