摘要： PROBLEM TO BE SOLVED: To avoid the resonance of a building not only with the short-period components but also with long-period components of earthquake motion. SOLUTION: This base isolating method includes base-isolating and supporting a building 1 by means of a plurality of base isolating devices 2A, 2B and causing the natural period of the building 1 to deviate from the period of earthquake motion by changing some of the base isolating devices 2B into sliding supports according to the period of the earthquake motion. This base isolating system includes the base isolating devices 2B base-isolating and supporting the building 1 and capable of being changed into the sliding supports, a sensor 4 for sensing the period of earthquake motion, and a control device 3 for controlling the base isolating devices 2B according to the result of detection by the sensor 4 so that they are changed from base-isolating supports into the sliding supports. Sliding plates 5 secured to the building 1 are connected to the base isolating devices 2B by connecting mechanisms 6, which are actuated by an operation signal from the control device 3 to disconnect the sliding plate 5 from the base isolating devices 2B.

摘要： PURPOSE: To embody high damping properties of a building by constituting a building with girders and beams and floor joists having a complex structure which comprises a steel pipe concrete post and structural steel and concrete. CONSTITUTION: Posts 2 of a high damping building 1 consist of a square-shaped steel pipe and concrete placed in a the pipe, thereby constitutine a ≃illing steel pipe' concrete post. Then, girders 3 and beams 4 are designed in steel concrete complex structure wherein concrete is placed in H shape or more precisely between its flanges and web. Then, floor joists 5 consist of a steel- made square pipe and concrete placed inside the pipe. A grating 6 is installed on the floor joists 6, thereby constituting a floor. An H steel compound pier 7, which supports the lower part of the girders 3, are installed to the central part of the girders 3. Each structural body forms a structural steel concrete complex body wherein structural steel and concrete are integrated in one piece, thereby providing higher rigidity compared with structural steel structure. This construction excels in damping properties and further enhances damping properties to a more satisfactory extent by supporting the lower part of the girders 3 with the compound pier 7.

摘要： PURPOSE:To enable handy measurement of fine vibration of various equipments, by housing a vibration meter, an amplifier, a waveform recording means and a battery power source into one trunk case. CONSTITUTION:An accelerometer (vibration meter) 4 is removed from a trunk case 1 to be set at a vibration measuring point, measures acceleration due to fine vibration at the point and outputs a detection signal corresponding to the acceleration to be inputted into an amplifier 5 in the case 1. The amplifier 5 has a function of amplifying measuring signals as intact or a function amplifying the acceleration once converted to a speed or displacement and these three functions can be selected according to a measuring mode. A pen recorder 6 records an amplifier waveform of an output signal of the amplifier 5 continuously on a recording paper being fed at a constant speed. A max. value digital display device 7 displays the max. value of the output signal thereof 5 digitally. A battery 8 and a charging circuit 9 are housed into the case 1 to drive all devices therein 1. The accelerometer 4 and a power source cable 10 are housed into an S section.

摘要： PROBLEM TO BE SOLVED: To provide a method for controlling active base isolation, which can implement optimum vibration control according to the circumstances of an installation location and the capacity of an actuator. SOLUTION: There is employed a method for controlling the active base isolation, in which an evaluation function in optimum feedback control is determined by independently weighing the absolute acceleration and the relative displacement of a floor 2A or a building 2B. According to the method, not only both the absolute acceleration and relative displacement of the floor 2A or the building 2B can be reduced, but also it is determined which amount of the absolute acceleration and the relative displacement can be emphatically reduced.
