摘要： PROBLEM TO BE SOLVED: To establish a fireproof specification standard of high-strength concrete, and to easily select a fireproof specification consistent with required fire resistance efficiency.
SOLUTION: The fire resistance efficiency is divided in two, that is, anti-explosive-fracture performance and skeleton temperature suppressing performance, the guaranteed fire resistance efficiency means satisfying the conditions that a fire resistance hour at least until the start of an explosive fracture is 90 min or more and that a fire resistance hour capable of holding a concrete temperature in a reinforcement position to 200°C or lower is 90 min or more, the fireproof specifications, which satisfy the conditions, are pre-classified into a plurality of ranks for each secured time until the start of the explosive fracture in terms of the anti-explosive-fracture performance, and pre-classified into a plurality of ranks for each secured time, capable of holding the concrete temperature in the reinforcement position to 200°C or lower, in terms of the skeleton temperature suppressing performance, an anti-explosive-fracture fire resistance hour and a skeleton temperature suppressing fire resistance hour, which are required for the target high-strength concrete member, are determined, and the fireproof specification, which satisfies the required fire resistance hours, is selected from among the fireproof specifications as alternatives.

摘要： PROBLEM TO BE SOLVED: To provide a structure for preventing explosive fracture of concrete, which simplifies execution of work, which effectively prevents the explosive fracture of the concrete while using a low-cost material, which satisfies three-hour fire resistance efficiency required by the Building Standard Law, and which can hold a concrete temperature in a reinforcement position (as a measure, a position at a distance of 50 mm from a concrete surface) to 200°C or lower.
SOLUTION: A surface of a concrete member is covered with a calcium silicate plate with a thickness of 25 mm or more, or covered with a ceramic-based fire resistive covering material with a thickness of 20 mm or more, which preferably contains a supersulphated calcium aluminate.

摘要： PROBLEM TO BE SOLVED: To provide a floor vibration suppression device capable of stably reducing solid propagation noise or floor vibration over a wide frequency range from several Hz to several hundreds of Hz that becomes a problem of production, investigation or living performance because of floor multi-degree-of-freedom vibration.
SOLUTION: There are provided a sensor for detecting vibration of a damping target floor, a controller for controlling an actuator by determining an actuator manipulated variable for reducing vibration and solid propagation noise from a detection signal of the sensor and a dynamic characteristic model of the damping target, and the actuator which is controlled in driving by the controller and generates vibrating power. The controller is designed by representing a model error internally existing in the dynamic characteristic model of the damping target floor using a normalized left irreducible resolution, using a frequency weight function taking into account control performance and robust stability, and solving an H infinite sub-optimal control problem without γ-repetition.

摘要： PROBLEM TO BE SOLVED: To provide an inspection method and an inspection system of a water leak spot capable of specifying a water infiltration spot outside the building quickly in a comparatively short time and surely.
SOLUTION: An ultrasonic wave is made incident together with compressed air from the water leak spot 11a inside the building, and the ultrasonic wave in the compressed air propagated to the outside of the building through a crack 12 and a gap in the building structure which are a water leak route is measured, to thereby probe the water leak spot 11b outside the building.
