abstractA discussion is made of the wind force coefficients for designing the main wind force resisting systems of H.P.  (Hyperbolic-Paraboid)-shaped porous canopy roofs on the basis of a wind tunnel experiment. Roof models with a number of small circular holes were made of nylon resin using laser lithography. The porosity was changed from 0 (solid) to 0.4. Besides the porosity, the geometric parameters of the models were the rise to span ratio and slope of the roof. The overall aerodynamic forces and moments acting on a model were measured by a six-component force balance in a turbulent boundary layer. The results indicate that the porosity significantly reduces the wind loads. The design wind force coefficients for porous canopy roofs can be provided by those for solid roofs with the same configuration multiplied by a reduction factor. The proposed wind force coefficients are verified by a comparison of the load effect predicted by the proposed wind force coefficients with the maximum load effect obtained from dynamic analyses using the time history of wind force and moment coefficients. The axial forces induced in the columns supporting the roof are regarded as the load effect for discussing the design wind loads.

5.        Buckling of Open-topped Oil Storage       Buckling of Open-topped Oil Storage Tanks under Static Wind Loading

14th International Conference on Wind Engineering, Porto Alegre, Brazil, June 21-26, 2015.6

 

ABSTRACT: The present paper investigates the buckling behavior of open-topped oil storage tanks made of thin steel sheets and stiffening rings (wind girders) under static wind loadings based on a finite element analysis. The distributions of wind force coefficients Cf, or wind pressure difference coefficients on two or three tank models arranged in line are measured in a turbulent boundary layer. Measurements are also made for isolated models for comparison. The aspect ratio (height/diameter) H/D of the model is changed from 1.0 to 0.25 and the radius to thickness ratio R/t from 500 to 4000. The non-dimensional gap spacing S/D between models is changed from 0.125 to 1.0. The results on the mean wind force coefficients Cf_mean are used for the buckling analysis. First, the buckling behavior (i.e. buckling load and mode) of open-topped tanks with rigid wind girders installed at the top are investigated. Focus is on the effect of circumferential Cf_mean distribution on the buckling behavior. The results indicate that the distribution of positive Cf_mean values in the windward area affects the buckling load significantly. Then, the effects of the top and intermediate wind girders on the buckling behavior of ring-stiffened tanks are investigated. When the non-dimensional flexural rigidity  of wind girders is larger than a critical value depending on H/D and R/t, the buckling load is little affected by . In such a case the buckling mode does not involve the deflection of wind girders. An empirical formula is provided for predicting the buckling loads of ring-stiffened open-topped oil storage tanks.

 

6.           Study on load resistance of elastically-supported window glass

14th International Conference on Wind Engineering, Porto Alegre, Brazil, June 21-26, 2015.6

 

   ABSTRACT: The strength of elastically-supported glass plates subjected to wind load was investigated by performing full-scale breakage tests and numerical simulation that can predict glass failure pressure. Full-scale breakage tests were carried out using window specimens whose edges are supported as used in practice in order to validate the applicability of numerical simulation for the elastic support condition. The results indicate that the numerical simulation can capture full-scale breakage test results by adjusting parameters related to the material characteristics and testing environments, especially relative humidity, RH. In addition, current regulations for evaluating the wind-resistance of glass plate in Japan, USA and Australia were examined by comparing the results obtained from the numerical simulation. As a result of comparison, it is shown that the load resistance in Japan is likely to overestimate the wind-resistance of glass plate and not to capture the effect of window size and its aspect ratio compared to those obtained from other countries’ code.

 

 

7.           INFLUENCE OF RIDGE HEIGHT OF PIPE-FRAMED GREENHOUSES ON WIND PRESSURE COEFFICIENTS

ABSTRACT: Taller pipe-framed greenhouses (pipe houses hereafter) are required to maintain a buffer zone for an improved thermal environment or to install devices for controlling the thermal environment, such as movable curtains. This study investigates the effect of ridge height on the distributions of the wind pressure coefficient (Cp) on pipe houses based on a wind tunnel experiment using 1:20 scale models. The width and length of a standard pipe house in full scale were 6 and 50 m, respectively, while the ridge height was varied from 3.16 to 5.16 m. The results indicate that the Cp distribution on the windward roof was strongly affected by the ridge height when the wind direction was normal to the ridge line. The windward roof was generally subjected to negative wind pressure (suction). The suction had a maximum value behind the windward eave, which increased in magnitude with an increase in ridge height. This effect may be related to the flow separation at the windward eave and reattachment on the windward roof. As a result, the drag and lift coefficients (CD and CL) obtained from the Cp distribution were also affected by the ridge height. High suctions were induced locally at the ridge corner of the leeward roof with an oblique wind.

10th International Symposium on Advanced Science and Technology in Experimental Mechanics, 1-4 November, 2015, Matsue, Japan, 2015.11

 

Abstract : Design wind force coefficients are proposed on the basis of wind tunnel experiment. Three different gable-end conditions are tested; i.e. enclosed type, open type (without gable walls) and partially enclosed type (with one gable wall). The wind pressures are simultaneously measured at many points both on the external and internal surfaces in a turbulent boundary layer. First, the features of mean wind force distributions are made clear. Then, the design wind force coefficients are discussed, where focus is on the load effect induced by wind loads. Based on the results obtained from a series of wind tunnel experiment and structural analysis, we propose a simplified model of the wind force coefficients for the main wind force resisting systems by using the LRC method.

Abstract : The present study examines the wind-induced behaviour of free-standing membrane canopy roofs with various types of roof-supporting systems and presents wind force coefficients for designing such roofs.  The effects of roof deformation and choice of roof-supporting system on wind force coefficients are investigated. The characteristics of wind-induced responses of the roofs are taken into account for improving the wind force coefficients that we previously proposed based on the results of wind tunnel experiment with rigid roof models.

Abstract : The present paper discusses the mechanism of the wind-induced scattering of permeable unit flooring decks loosely laid on the rooftops and balconies of high-rise buildings. Firstly, the scattering mechanism of decks was investigated, based on a blowing test using a blower and actual decks. Subsequently, a simulation model was constructed for estimating the internal pressures under the decks (pressures acting on the bottom surface of decks) obtained from a wind tunnel experiment – this is based upon the unsteady Bernoulli equation and the time history of external pressures on the rooftop and balconies. Combining the simulated internal pressures and the experimentally obtained external pressures, the time history of net wind pressures acting on the decks were computed. Finally, the threshold wind speed of scattering (scattering wind speed) was obtained by applying the scattering mechanism to the simulated time history of the net wind pressures.

 

25.   Relationship between Surface Roughness and Turbulence of Natural Winds near the Ground Surface

Ryoji Sasaki, Akinori Akahoshi, Yasushi Uematsu

Technical Transactions Civil Engineering 2015, 2-B, pp.317-330, 2015.12

 

Abstract : The design of low-rise buildings such that they can handle wind loads makes it necessary to accurately evaluate those wind loads, both on the structural framework and on the cladding/components. To this end, it is necessary to fully understand the characteristics of the wind near the ground around a building. This study sets out to develop a quantitative means of estimating the turbulence of the wind near the surface of the ground, based on field measurements obtained at different points across Japan. The surface roughness is evaluated based on several factors taken from a building information database. The relationship between these factors and the turbulence of the wind is discussed. The effect of the observation height, relative to the surface of the ground, on the turbulence is also investigated.

Investigation on Wind Resistance Evalualtion Method of Composite Sidings with Metal

Journal of Structural and Construction Engineering, Transactions  AIJ,Vol. 81, No. 720, pp.377-383, 2016.2

 

Abstract : For the determination of wind resistance of cladding materials, tests with specimens whose size is relatively small and represents a part of the cladding system, using simplified test setups (i.e., a partial component test) tend to be performed due to their simplicity and the technical testing capability of cladding manufacturers. However, the differences between failure load (pressure) of claddings obtained by such simplified methods and that obtained under more realistic loading with specimens fully representing actual cladding systems (i.e., a complete component test) are not generally quantified. The present study examines this difference in failure loads by performing complete component tests and partial component tests using a wall system employing composite siding with metal, and discusses the parameters which influence failure loads.
