摘要： PROBLEM TO BE SOLVED: To impart a damping function to a slab by forming a joint at least at a part of depth of the total thickness in the thickness direction of a slab at a part of the slab and filling a damping material in the joint. SOLUTION: A damping material 3 such as silicon, aluminum, highly damping rubber, etc., is filled in a joint 2 formed at least at a part of depth of the total thickness, in the thickness direction of a slab 1 at a part of the slab 1. A plane framework II positioned at the center in the Y-direction in three plane frameworks I, II, III constituting the structural face in the X-direction bears a larger horizontal load than the plane frameworks I, III at the action of a X-directional horizontal force from the dominant area of a column 5. Then, the damping slab 1 is adapted for a part or the whole of respective floor slabs in stories of a building having a structure constituted of columns, beams, and walls. Accordingly, vibration of a structure can be effectively damped.

摘要： PROBLEM TO BE SOLVED: To provide a hybrid earthquake control floor capable of effectively controlling the vibration of a floor frame with a minimum energy supply and of coping with even a large earthquake. SOLUTION: A structural floor 3 and a floor frame 4 supported in such a way as to be horizontally movable relative to the structural floor 3 are connected together by a passive base isolator 5 having damper functions and by an active earthquake control device 6 having a drive 6a and a control means 6b which apply a control force for controlling the relative vibrations of the structural floor 3 and the floor frame 4 according to vibration caused by an earthquake, etc. The damping coefficient cd of the passive base isolator 5 is set at an appropriate value matching device characteristics, so that all the vibrational energy input is consumed by the passive base isolator 5, and that the control energy required of the active earthquake control device 6 is minimized.

摘要： PROBLEM TO BE SOLVED: To form a structural member simultaneously supporting a vertical axial force and a horizontal shearing strength by lead, which has been so far considered impossible by a relatively simple constitution. SOLUTION: Steel plates 4 and lead plates 5 are laminated alternately between upper-lower steel plates 2, 3 for installation by holding the lead plates by the steel plates, and the steel plates, 2, 3 for installation, the steel plates 4 and the lead plates 5 are welded and a laminated lead bearing 1 is constituted. The state of the internal stress of lead is brought to a triaxial-stress state by thinning a lead layer and the maximum shear stress on the inside and the free surface is reduced to a low value, a vertical elastic modulus is increased, and the degree of compressive stress, in which the degree of maximum shear stress on the inside and the free surface reaches the degree of creep critical stress, is increased largely.

摘要： PURPOSE:To effectively reduce a seismic response to the wide range extending from a weak or strong earthquake to a disastrous or ruinous earthquake, by a method wherein an active type seismic control apparatus is provided on the upper of a structural frame and passive type seismic control apparatus each are located at the lower floors of the structural frame. CONSTITUTION:An active type seismic control apparatus 2 with dynamic vibration reducers is provided on the upper part of a structural frame 1 and an passive type seismic control apparatus 3 with elasto-plastic dampers is located at each of the lower floors thereof. When a weak or strong earthquake below a very strong earthquake occurs, the apparatus 2 displays the effect of controlling the movement of the structural frame 1 and reduces a seismic response. When a very strong disastrous earthquake occurs, some of the elasto-plastic dampers in the apparatus 3 yield, absorb vibrational energy, and reduce the responce. Under such conditions, furthermore, the apparatus 2 displays the effect and reduce the response more and more. When a disastrous or ruinous earthquake occurs, the rest of the elasto-plastic dampers in the apparatus 3 all yield, absorb the vibrational energy, and reduce the response. In this case, the apparatus 2 is also actuated and reduces the response.

摘要： PURPOSE:To securely exhibit vibration isolating performance by introducing a to some of a plurality of laminated rubber bearing bodies which bear an additional mass body, and introducing tensile strength to the other rubber bearing bodies. CONSTITUTION:Thin rubber pads and steel sheets are laid alternately in layers while they are adhered one to another, and laminated rubber bearing bodies 1, 1, 2 are formed. A plurality of such rubber bearing bodies 1 are installed around an additional mass body 3, and a single piece of rubber bearing body 2 is installed in the center of the mass 3. A tensile strenyth of the specified magnitude is introduced to the bodies 1 lying peripherally, while a compressive force of a certain size is introduced to the body 2 in the center. Accordingly the peripheral bodies 1 receive small compressive force and share the horizontal rigidity and flexural rigidity for the whole without risk of buckling, while the central body 2 bears the thrust force for the whole. Therefore, the bodies 1, 2 bear a large load in proportion to their section areas, support the additional mass body stably, and functions as a dynamic absorber for long period of vibration.
