摘要： PROBLEM TO BE SOLVED: To prevent the layer collapse of a pilotis layer by the elastic rigidity of a steel column in a large earthquake by winding an iron plate, carbon fiber or the like around the existing column of the pilotis layer to reinforce it, and establishing a steel column more near the existing column. SOLUTION: For the aseismic reinforcement of an existing RC building 1 having a pilotis layer 2 in the base floor part, an iron plate or carbon fiber is wound around an existing column 3 to perform an aseismic reinforcement 4, and a steel column 5 is established more near the existing column 3. The upper part of the steel column 5 is rigidly connected to the building 1 by pinning or integration by welding. According to this, in a large earthquake, the existing column 3 improved in toughness by the aseismic reinforcement 4 supports the load of the building 1 without reducing the axial yield strength even if plasticized, and the response deformation is reduced by the elastic rigidity of the established steel column 5, so that the layer collapse of the pilotis layer 2 can be prevented. Thus, an opening part can be ensured without establishing a crossing brace or an earthquake-resistant wall between the existing column 3, and the aseismic reinforcement of the pilotis layer 2 can be performed.

摘要： PROBLEM TO BE SOLVED: To improve the vibration control capacity at a low cost, by assembling a member absorbing the displacement energy at the time when a plurality of beams are relatively displaced in the horizontal direction, between the beams positioned at the upper and lower sides in the building frame of a structure and forming the member absorbing energy by using a vertically extending hollow cylindrical body. SOLUTION: In a building frame 1 chiefly constituted of columns 2 and beams 3, a damper 5 is erected as a stud forming a vibration-resistant element at the central part of vertically arranged beams 3, 3. The damper 5 is connected to respective beams 3, 3 and provided with an energy-absorbing member (cylindrical body) 8 between vertically extending brackets 6, 7. The energy-absorbing member 8 is formed of an extremely mild steel pipe with a square section having a lower yield strength than the column 2, the beam 3, and the brackets 6, 7 and the upper and lower ends thereof are connected to the brackets 6, 7 respectively. In this way, when two-directional horizontal external forces resulting from an earthquake, strong wind, etc., act on the building frame 1, the horizontal relative displacement energy of the upper and lower beams 3, 3 can be absorbed.

摘要： PURPOSE: To allow a structure incorporating a yielding type brace with enhanced buckling resistance to have great stress damping by forming the brace shaft of the yielding brace from a very-low-yielding-point steel. CONSTITUTION: The main spindles 2, 2 of brace shafts 4, 4 are each so formed to have a cruciform cross section, and skeleton mounting portions 3... are provided at both ends of the main spindles 2, 2. Concrete is cast around the main spindle 2 to form precast concrete. In this yielding type brace 1, the brace shaft 4 is constructed of a very-low-yielding--point steel. When integrated into the framework of a steel structure the early yielding type brace 1 is unlikely to buckle even at the application of a compressive force during an earthquake, and is allowed to reach its yielding point at early stages of application of a tensile force, thereby absorbing that external force. As a result, the steel structure incorporating the brace 1 can be made to have great stress damping.

摘要： PURPOSE:To improve safety by cutting out the web of the H-type shape steel beam between a large diameter and small diameter steel pipe column and inserting truncated conical joint members whose bottom surfaces are equal to the sections of steel pipe columns respectively to weld all joints of respective steel pipes, joint members and steel beams. CONSTITUTION:In a large diameter steel pipe column 1 on the second floor, a lower edge is butt-welded to the top surface of an upper flange 4a of a H-type steel beam 4, and a small diameter steel pipe column 2 on the first floor is cut out toward a web 4c from the lower flange 4b of the beam 4 and an upper edge is penetrated to weld a seamed portion. In a conical headed joint member 3, one bottom is formed so that it may be equal to the section of a column and the other bottom is formed so that it may be equal to the section of a column 2 respectively, and the web 4c is cut out to insert the member 3. Then a large diameter bottom is butt-jointed to the lower surface of the flange 4a on the column 1 side and a small diameter bottom is butt-jointed to the upper edge of the column 2 respectively to weld respective seamed portions and transmit the axial force of the column 1 to the column 2 through the member 2. It is thus possible to improve safety.

摘要： PROBLEM TO BE SOLVED: To improve the executability by preventing a corner part of a connection part from a shearing yield part to a mounting part from becoming a right-angled shape when the shearing yield part is joined on a support member in the mounting part. SOLUTION: A corner part 10 of a connection part 9 in which a steel damper 6 moves from a shearing yield part 7 to a mounting part 8 is not right-angled, but is like round shape to prevent weakening due to the concentration of stress at the time of machining and prevent cutting of the corner part 10 only due to the concentration of stress in the corner part 10 when earthquake occurs. Next, the damper 6 is joined on a support member by a high strength bolt through a bolt hole 12 while pressing the mounting part 8 by a pressing plate or the mounting part 8 and the connection part 9 are welded on the support member by fillet welding. Then, when a ratio of width to height of the yield part 7 is large, a rib led to the mounting part 8 is attached to both sides of the yield part 7 by fillet welding to prevent bending deformation which is independent of deformation between layers. Consequently, the deformation between layers due to horizontal force of earthquake can be securely transmitted to the shearing yield part and this steel damper can be manufactured inexpensively because its structure is simple and can be easily mounted because its weight is light.
