摘要： PROBLEM TO BE SOLVED: To more accurately and simply obtain a yield strength of a joint part of a steel pipe column and a beam with less trouble. SOLUTION: A collapse mechanism of a joint part K2 of a steel pipe column C having a concrete 2 filled in an inner hollow part and a steel framed beam B is specified by a yield line and a flat plate part surrounded by the yield line. According to the method, a yield strength of the joint part K2 is obtained with the use of a yield line theory whereby the yield strength of the joint part K2 is derived from a yield criterion of a section at the yield line. In the method, the steel pipe column C is considered separately between the joint part K2 with a pipe thickness increased, and general parts K1 continuous with the joint part up and down. A pipe thickness tp of the joint part K2 and a pipe thickness tc of the general part K1 are set separately. In obtaining the yield strength of the joint part K2, a distance Lp between an upper end part of the joint part K2 and an upper end part of the steel framed beam B, and an axial force acting to the steel pipe column C are reflected to the yield line theory.

摘要： PURPOSE:To restrain vibration of a floor in the vertical direction caused by stationary vibration by connecting an auxiliary supporting member to a spindle, by movably providing a supporting point member acting on this, and by providing a control mechanism for automatically moving the supporting point member based on information of a vibration sensor provided on the floor. CONSTITUTION:When a floor W vibrates, a frequency Fw of the floor W is measured all the time by a vibration sensor 15, and as the frequency Fw is changed due to change in a load imposed on the floor W, for example, as the load is increased and the frequency Fw is reduced, a working position against an auxiliary supporting member 6, that is, the working position of a plate spring supporting roller 11 against a plate spring 5 is moved away from a plate spring supporting member 4. To the contrary, as the load is reduced and the frequency Fw is increased, the working position of the roller 11 against the spring 5 is brought close to the member 4 side, and a servo motor 12 (driving mechanism) is driven and controlled by a control circuit 17 so that a frequency Fm of a spindle M by a vibration sensor 16 accords with the frequency Fw, by which the frequency is reduced and generation of resonance is avoided.

摘要： PURPOSE:To appropriately adjust a spring constant by regulating the relative movement direction of two magnets in a facing direction in a condition where magnetic poles having the same polarity are faced to each other in two magnets to adjust the maximum separation distance of the magnets in a condition where the approach and movement of two magnets to/from each other are allowed. CONSTITUTION:A magnet 1A is fixed to the upper surface of a floor A, and a magnet 1B is fixed to a place opposite to the magnet 1A on the lower surface of an additional vibrator B. That is, both the magnets 1A and 1B move relatively far and near in a vibration direction following the relative vibration between the floor A and the addition vibrator B. Two magnets 1A and 1B are fitted into a condition where magnetic poles having the same polarity are faced to each other. The maximum separation distance of the addition vibrator B to the floor A is changed to adjust the maximum separation distance DMAX between the magnets 1A and 1B by vertically change the position of an upper stopper 4 to a tension member 2 to change the vertical position of the upper stopper 4 to a lower stopper 3.
