摘要： PROBLEM TO BE SOLVED: To reduce the quantity of crosswind on the upper face of a structure by connecting air intake ports provided on the side part of a structure to air blowout ports upward opening through ducts. SOLUTION: Many air intake ports 2 receiving crosswind W are provided in a line on the side part of a structure such as a bridge girder 1, and air blowout ports 3 opening upward are formed on the upper face of the side part of the bridge girder 1. The air intake port 2 and the air blowout port 3 are connected together through a duct 4. Then, when the crosswind W blows, air flowing in from the air intake port 2 passes through the duct 4, and blows out upward from the air blowout port 3. Hereby, the quantity of crosswind W on the road 5 on the upper face of the bridge girder 1 is reduced, and safety of running of a vehicle 6 and the like can be assured. It is unnecessary to provide a high wind shield wall on the side part of the bridge girder 1, and degradation of sceneries and wind resisting stability can be avoided.

摘要： PROBLEM TO BE SOLVED: To provide a main girder of a cable stayed bridge whose main girder for realizing the cable stayed bridge having excellent stability and resistance against wind is constituted of a sheet metal girder and an installation method therefor.
SOLUTION: A web 10c constituting the main girder 1 of the cable stayed bridge constitutes the main girder 1 in such a way that it is inclined for the vertical direction. When the cable stayed bridge is formed using this main girder 1, the webs 10c are installed in both side parts of the cable stayed bridge in such a way that lower parts of the webs 10c have such inclination that they are gradually separated onto an outer side or they approach an inner side gradually. Moreover, a hole 10d is formed in the web 10c to provide a wind passage partitioned by a horizontal girder 2.

摘要： PROBLEM TO BE SOLVED: To provide a parallel bridge-damping device for suppressing aerodynamic vibration effectively with less expenses in a parallel bridge where at least two bridges are erected in parallel. SOLUTION: A newly installed bridge 1 is erected in parallel with an already installed bridge 2 to form a parallel bridge. The balustrade of the newly installed bridge 1 that becomes the winward side of wind 6 that blows toward the parallel bridge is set to a post type balustrade, thus passing one portion of the wind 6 blowing toward the parallel bridge through the space of the post type, making gentle the wind flow at the upstream side of the parallel bridge, and hence reducing the amplitude of aerodynamic vibration.

摘要： PROBLEM TO BE SOLVED: To generate gas flow for generating a turbulence similar to natural wind having a plenty of change by respectively projecting a plurality of horizontal members from a plurality of rockable shafts rotatably stood in a vertical direction in a wind tunnel, mounting a cloth-like member at the same member, and individually providing rocking driving means at the respective shafts. SOLUTION: Rockably driving motors 61 to 63 are operated to rock closes 31 to 33, 131 to 133, and an angle between a pair of clothes 31 and 131 rocking laterally symmetrically is regulated to control main components of turbulent scale and strength. The clothes are divided into three in a vertical direction. Since the clothes of respective stages can be individually regulated at rocking angles, vertical direction components of turbulence strength and scale can be controlled. The motors 61 to 63 are controlled based on a set value previously input to a controller 10. At this point, since the cloth 31 is rocked at a vertical axis along a vertical edge side of a fixed triangular plate 4 as a center, symmetrical turbulent flows at a horizontal bottom edge side of a triangular plate 4 are generated in the tunnel by rocking of the cloth 33.

摘要： PROBLEM TO BE SOLVED: To sufficiently increase fluttering limit wind velocity, and to improve flutter-resistant performance. SOLUTION: A wind flowing on the top face and underside of a box girder 2 is introduced into an opening section 4 and passes through the underside and top face of the box girder 2 in the case of the wind (the wind blowing up and the wind blowing down to a horizontal wind) or the like within a range of an elevation of ±3 deg. by the working of a central wind-shielding wall 6, an end-section wind-shielding wall 7 and an inspection-car rail 8. Accordingly, the pressure difference of the top face and underside of the box girder 2 is relaxed, self-excited aerodynamic force working to the box girder 2 can be reduced, and fluttering limit air velocity can be increased largely. Since the wide opening section is not required, pavement for a lane can be ensured sufficiently. Since wind velocity on the lane is reduced by the end-section wind- shielding wall 7, the traveling safety of a car can be ensured. Since the inspection-car rail 8 is used with an underside-side end-section wind-shielding wall in common, a structure is simplified so much, and a material for a bridge can be economized.

摘要： PROBLEM TO BE SOLVED: To more effectively suppress generation of a flutter and increase the wind velocity generating a flutter. SOLUTION: Two main cables 1, 2 hanging a bridge dirder 4 suspended between basal chief towers cross each other at the middle position in the axial direction of a bridge. Hanger ropes 5, 6 to hang down the bridge girder 4 from the main cables 1, 2 are obliquely inclined halfway. The main cables 1, 2 are positioned on two perpendicular faces crossing each other. A position in the bridge-axial direction where two main cables cross each other is the geometrical mid-point (middle point) between the chief towers. The rigidity of the two main cables themselveas crossing each other is improved with respect to torsion on installing them and the tortional frequency is increased. Hence, a wind velocity generating a flutter is increased.
