摘要： PURPOSE:To enhance the safety of construction work by controlling vibration of a main girder overhanging section by mounting a large block of a main girder on a bent provided around the main girder section, and providing a controller acted widthwise of the main girder between the main girder overhanging end of the bent and main girder. CONSTITUTION:A large block main girder 3B of a main girder 3a is mounted on a wire bent 20 provided to a bridge pier 21 erecting main towers 1 and 2 through a bearing body capable of sliding widthwise. The large block main girder 3B is connected to diagonal tension cables 5. A vibration controller 22 is provided near the end on the center span side of the wire bent 20, and lateral and horizontal runout vibration caused by wind of the overhanging end 3b of the main girder 3 can be controlled by the vibration controller 22. According to the constitution, horizontal vibration generated in a main girder overhanging section during the construction of a diagonal tension bridge having a longer overhanging length is controlled, and danger can be prevented during the construction of erection work.

摘要： PURPOSE:To permit one measure to cope with both bending and torsional vibrations by a method in which an arm is provided extensionally from the torsional center to the direction of bending vibration on the top of a tower structure and a measure is set on the top. CONSTITUTION:An arm 6 is set extensionally at a position a given distance (l) apart in the direction Y of bending vibration from the torsional center O of the top 2 of a tower structure, and a mass M is set on the top of the arm 6. The mass point M is replaced with the displacement in the direction Y and the vertical direction X by multiplying the length (l) by torsional angle theta. For the binding vibration, the mass M and the spring KY in the direction Y is worked to match its intrinsic period, and for torsional vibration, the mass M and the spring KX in the direction X is worked to match its intrinsic period.

摘要： PURPOSE:To raise durability of a ship buffering work by avoiding the exposure of constituents to sea water for the ship buffering work to prevent damage to the main tower base by collision of ships by providing it for the surrounding of the main tower base to support the main tower of suspension bridge and skew bridge. CONSTITUTION:In a buffering work 10 to be attached to surroundings of a main tower base, steel tubes are arranged vertically and horizontally by biasing the heightwise and widthwise directions of the tubes into a well-cribbed form to form a framework. The periphery of the framework is covered with a concrete wall 19. The framework is attached to the surrounding of the main tower base 2 through fitting parts 16 to prevent the intrusion of sea water into the buffering work, and the corrosion of the constituents by sea water can also be prevented. The impact energy-absorbing function of the buffering work can thus be stably kept for long periods.

摘要： PURPOSE:To prevent the generation of vibration by providing many recesses and projecting parts to be distributed uniformly at matal spaces on the outer surface of a polyethylene tube for covering the main body of a cable, thereby separating the flow of a wind from the tube surface. CONSTITUTION:A wind 21 blown to a cable is separated from the outer surface of a cable to produce a flow 22 at every edge part of many recesses 20 or projecting parts on the outer surface of a cable. Subsequently, the flow extinguishes Karman's vortex existing leeward form the cable so as to restrain the production of overexcited vibration caused by Karman's vortex and wake galloping vibration when the vibration is suddenly developed. Water paths formed above and below a cable by a wind are interrupted by a separation flow 22 not to form a continuous water path. The overexcited vibration of the cable caused by water paths formed in specified positions on the upper and lower sides of the cable can be more surely prevented. Thus, the damping action can be improved, a covering polyethylene tube can be manufactured easily and laid easily, and damage can be reduced.

摘要： PURPOSE:To adjust the buoyancy of a buoyancy structure easily and particularly while lightening the load received from waves of the buoyancy structure regarding the buoyancy structure used for a floating breakwater, a floating pier, etc. CONSTITUTION:In a pontoon type buoyancy structure 1, a water passage structure section 4 for adjusting buoyancy extended so as to penetrate or notch at least the water-surface lower section of the structure 1 is installed. In the water passage structure section 4, not only the buoyancy of the buoyancy structure 1 is adjusted by setting the area of the water passage of the structure section 4 but also the free movement of external water is allowed in the water passage in the required direction such as the horizontal direction including the lower section of a water surface or the vertical direction or the like. The water passage structure section 4 in the horizontal direction reduces a wall area under the water surface of the buoyancy structure 1, and the water passage structure section in the vertical direction diminishes oscillation (pitching moment) in the longitudinal direction of the buoyancy structure and lightens wave pressure and water pressure applied to the buoyancy structure 1.

摘要： PURPOSE:To provide simplified constitution with facilitated maintenance by interposing a damper capable of following up the relative displacement of vibrating main towers and stiffening girders between both towers and girders along the bridge axis of a suspension bridge, cable stayed bridge, etc. CONSTITUTION:An oil damper 10 capable of following up the vibration of main towers 1, 2 is interposed between the main towers 1, 2 and stiffening girders 5, 5 along the bridge axis in a suspension bridge, cable stayed bridge, etc., with the stiffening girders 5 itself being a fixed weight body. When bending vibrations are generated in the main towers 1, 2 by lateral wind or the like, the damper 10 absorbs vibrational energy while following up the relative displacement of the main towers 1, 2 and stiffening girders 5, 5 and quickly damps and restrains the bending vibrations of the main towers 1, 2. Further it is desirable to prevent the main towers 1, 2 also from the torsional vibration by providing left and right symmetrically the dampers 10.

摘要： PURPOSE:To economically erect a cable stayed bridge with a temporary supporting point utilized as an adjusting mechanism by adjusting the height of the temporary supporting point set at the time of erection so that the stress and the displacement of the various parts of a cable stayed bridge structure can come into a favorable condition in view of strength or construction. CONSTITUTION:The height (h) of a temporary supporting point 4, set at the time of erecting a cable stayed bridge, is adjusted so that the stress and the displacement of the various parts of an obliquely hanging bridge structure can come into a favorable condition in view of strength or construction. Then the temporary supporting point 4 is not only used as merely staging for erecting a girder but also is fully utilized as an adjusting mechanism for the stress and the displacement of structure.

摘要： PURPOSE:To improve wind-enduring stability by temporarily mounting an appendage in a corner part at the time of installing a tower, and changing the sectional form of the tower at a time during the time of installation. CONSTITUTION:Appendages 2 that improve aerodynamic flow are mounted adhering closely to the corner part of a tower section 1 at a time during the time of installation. And, materials of light-weight and easy to form such as shells of FRP, rubber, etc. and blocks of foaming polystyrol, etc. are used as the appendages 2. With these means, wind-enduring stability at the time of installing the tower is improved, and an aireddy energizing vibration of large amplitude possible to generate in low wind velocity can be damped.
