  • STUDY ON UNSTEADY WIND FORCE AND FLOW FIELD AROUND AN OSCILLATING FLAT-PLATE ROOF

    NAKAMURA Ryohei, TANIGUCHI Tetsuro

    Architectural Institute of Japan, Journal of Structural and Construction Engineering (Transactions of AIJ)  ( 763 ) 1153 - 1163 2019.09  [Refereed]

     View Summary

    During strong winds, flat-plate roofs are expected to oscillate up and down. In this study, to investigate the relationship between unsteady wind forces and flow field around an oscillating flat-plate roof, first, three-dimensional forced vibration test is performed in a wind tunnel. Next, the ability of computational fluid dynamics (CFD) with an overset mesh to simulate the flow around the oscillating roof is validated by comparing numerical results with those of the wind tunnel tests. Finally, coherent structures in the fluctuating wind pressure and velocity fields around the oscillating roof, extracted using complex proper orthogonal decomposition (CPOD), are discussed.

  • Study on Correlation between Pressure and Velocity Fields over a Flat Plate Roof

    Proceedings of 25th National Symposium on Wind Engineering    235 - 240 2018.12  [Refereed]

     View Summary

    <p>In the previous study, fluctuating characteristics of pressure field on a flat plate roof and three-dimensional velocity vector field over that have investigated individually using Computational Fluid Dynamics (CFD) and complex Proper Orthogonal Decomposition (POD) analysis. However, velocity and pressure fields are considered to be correlated each other. In this study, the coherent structure including fluctuating fields of velocity and pressure is examined. Using complex POD analysis considering the velocity and pressure simultaneously, it is shown that fluctuating pressure and velocity vector fields over the flat plate roof exhibits several coherent structures associated with vortex fluctuation and pressure propagation.</p>

  • LES EVALUATION OF WIND LOADS ON A FLAT PLATE ROOF BASED ON VALIDATION WITH COMPLEX POD ANALYSIS

    NAKAMURA Ryohei, TANIGUCHI Tetsuro

    Architectural Institute of Japan, Journal of Structural and Construction Engineering (Transactions of AIJ)  ( 743 ) 23 - 33 2018.01  [Refereed]

     View Summary

    In the previous study by the present authors, wind loads on the flat plate roof above a stand had been examined with wind tunnel experiments and Large
    Eddy Simulation (LES) which is expected to be used as a tool for the wind-resistant design of buildings. However, the computed and experimental results of
    the minimum peak pressure near the corner edge of the roof had not coincided with each other, where the wind blew diagonally for the model. In this paper,
    the peak pressures evaluated by using LES with high-resolution models are compared with the experimental results as statistics of wind pressures. And the
    fluctuating wind pressure fields are examined by using complex proper orthogonal decomposition (POD). Furthermore, the wind pressure distribution on the
    flat plate roof is evaluated in detail by using LES and coherent structures in the fluctuating wind pressure fields are discussed by using complex POD analysis.

  • Study on Wind Loads on a Cantilevered Roof above Stands by Wind Tunnel Test and LES

    Proceedings of 24th National Symposium on Wind Engineering    235 - 240 2016.12  [Refereed]

     View Summary

    Generally, the design wind loads for the cantilevered roof of stadiums have been determined with the pressure and/or force coefficients for partially enclosed buildings. However there are cases when the slits are installed between the roof and the stands of stadiums. Although the pressure and force coefficients in consideration with the slits are required in these cases, few studies are available on these coefficients.<br>This paper presents the force coefficients corresponding to the size of slits and pitch of a roof above stand. These coefficients are evaluated by wind tunnel tests and Large Eddy Simulation (LES) that has become available technique to evaluate the wind loads for tall buildings. By comparing the numerical analytic results with the experimental results, the availability of LES to evaluate wind loads on large roofs is examined. And also coherent structures on the pressure field obtained by LES is considered by using the complex Proper Orthogonal Decomposition (POD)

  • EXPERIMENTAL STUDY OF THE COMBINATION OF WIND LOADS USING WITH POD ANALYSIS

    Proceedings of 24th National Symposium on Wind Engineering    331 - 336 2016.12  [Refereed]

     View Summary

    This paper describes investigation on aerodynamic stability of 3-span continuous steel box girder bridge with main span of 185m. This bridge has very small B/d compared to the existing bridges, the possibility of galloping and vortex induced oscillation is predicted. So wind tunnel tests are conducted to investigate the countermeasure.First, wind tunnel test with sectional models are conducted and it is concluded upper and lower horizontal plate and flap are necessary to suppress galloping and vortex induced oscillation. Wind tunnel test with full bridge model is conducted to verify the countermeasure proposed with sectional model test under smooth flow and boundary layer turbulence.
