ABSTRACT: Wind loads on free-standing canopy roofs have been studied in a wind tunnel. Three types of roof geometries, i.e. gable, troughed and mono-sloped roofs, with roof pitches between 0o and 15o, were tested. Wind pressures were measured simultaneously at many points both on the top and bottom surfaces of the model for various wind directions. The paper describes the characteristics of the net pressures with special attention to the mechanism and estimation of the peak net pressure coefficients. The effect of obstruction under the roof on the peak net pressures is also investigated.

5th International Colloquium on Bluff Body Aerodynamics and Applications, July 11-15, 2004 , Ottawa , Canada , pp.449-452, 2004.7

 

ABSTRACT: The characteristics of wind pressures acting on circular flat roofs have been investigated based on the data obtained from a wind tunnel experiment. A simple model of the pressure field is provided as a function of the geometric parameters of building and the turbulence parameters of approach flow. A discussion is made of the application of the pressure model to the wind load estimation for the main wind force resisting systems of circular flat roofs, using the gust effect factor approach and the LRC method. The gust effect factor and the equivalent static loads derived from the pressure model are compared with those obtained from the time history of the pressures and the roof response. The results indicate that the pressure model can be used for evaluating the wind loads in the practical desig

ABSTRACT: The present study is focused on the structural design of steel structures with steel foundation-girders, and the purpose is to static seismic load taking the structures subjected to static seismic load taking the effect of soil-pile-structure interaction into consideration based on Chang's formulae. It is clarified that the combined approximations of uniform horizontal displacement with the rotational rigidities of the junctions of column-base and foundation-girders give accurate evaluations to the deformations and stresses of both the structures and the pile foundations.

Workshop on Regional Harmonization of Wind Lodings and Environmental Specifications in Asia-Pacific Economies, pp.61-83, 2004.

 

ABSTRACT: This paper first introduces the background to structural design of buildings in Japan . Then it introduces the 2004 version of the wind load provisions of the AIJ Recommendations for Loads on Buildings. The major revisions are as follows: replacement of gust loading factor based on tip displacement by one based on base bending moment; introduction of wind directionality factor (8 wind directions); explicit introduction of wind load combinations; correction and addition of topographic effects; substantial fulfillment of aerodynamic coefficients; and so on. Finally, the 2004 version of the AIJ Guidelines for the Evaluation of Habitability to Building Vibration is also introduced.

WIND FORCE COEFFICIENTS FOR THE MAIN FORCE RESISITING SYSTEMS AND CLADDING OF FREE-STANDING CANOPY ROOFS WITH SMALL ROOF PITCHES

Yasushi UEMATSU, Eri IIZUMI, Theodore STOTHOPOULOS

The 18th National Symposium on Wind Engineering, pp.329-334, 2004.

 

ABSTRACT: Wind loads on free-standing canopy roofs have been investigated in a simulated turbulent boundary layer. Three types of roof geometries, i.e. gable, troughed and mono-sloped roofs, with roof pitches between 0o and 15o, were tested. Wind pressures were measured simultaneously at many points both on the top and bottom surfaces of the model for various wind directions. The local net pressure coefficients and the overall wind force and moment coefficients were computed by using the pressure data. The paper first describes the characteristics of the overall wind forces and moments acting on the roof with special attention to the load combination for discussing the design wind loads; the axial forces induced in the four imaginary columns at the roof corners are considered as the load effect for discussing the design wind loads. Then, the characteristics of the local net pressures are investigated. A brief discussion is made of the peak net pressure coefficients for cladding design.

WIND LOADS ON A STEEL GREENHOUSE WITH A WIG-LIKE CROSS SECTION

The 18th National Symposium on Wind Engineering, pp. 347-352, 2004

 

ABSTRACT: The authors have proposed a new type of greenhouse with a cross section similar to a wing. Such a cross section reduces the wind loads and realizes a long-span structure. Simultaneous pressure measurements were made with a scale model in a simulated turbulent boundary layer. First, the effects of wind speed and surface roughness of the model on the pressure distribution were investigated; several kinds of commercial sand paper were used for roughening the surface. Then, the design wind load for the main force resisting systems is discussed, based on three kinds of evaluation methods, i.e. a time-history response analysis, the LRC method and a gust effect factor approach. The results indicate that the gust effect factor approach gives a reasonable result for winds roughly normal to the ridgeline, while it results in a wind load distribution different from those predicted by the other two methods for oblique winds. The LRC method generally gives a result similar to that of the time-history response analysis. However, the result depends on the load effect under consideration. The value of peak factor is also dependent on the load effect; it is generally larger than 3.5. Finally, the peak pressure coefficients for cladding design are briefly discussed.

MODEL OF FLUCTUATING WIND PRESSURES ON SPHERICAL DOMES FOR LOAD ESTIMATION OF CLADDING

Masumi NOGUCHI, Yasushi UEMATSU

The 18th National Symposium on Wind Engineering, pp. 353-358 , 2004

 

ABSTRACT: The characteristics of the fluctuating external wind pressures on spherical domes have been investigated based on the data obtained from a series of wind-tunnel measurements in simulated atmospheric boundary layers. Focus is on the 1st to 4th moments of probability density function as well as on the power spectrum of pressure fluctuations. First, the effects of the roof geometry on these factors are discussed. Then, the dome surface is divided into two areas, i.e. Gaussian and non-Gaussian areas, according to the values of skewness and kurtosis. Finally, a model of the pressure field on the dome, that is, the mean and root-mean-square fluctuating pressure coefficients, power spectrum and so on, is proposed as a function of the rise/span and eaves-height/span ratios of the dome. This model is used for simulating the fluctuating wind pressures in the Gaussian and non-Gaussian areas. The simulated time history of pressure fluctuations can be used for fatigue analysis and risk consistent and more economical design.

 

20. Structural characteristics and wind resistant design of spatial structures constructed in Japan

Eleventh International Conference, Lubbock , Texas , June 2-5,2003

 

ABSTRACT: The geometry, structural characteristics and wind resistant design method of spatial structures constructed in Japan in the last two decades have been investigated, based on a literature survey as well as on a questionnaire answered by structural engineers at some construction companies. Regarding the wind resistant design, focus is on the method of wind load estimation used in the practical design. The results indicate that the structural characteristics, such as the first natural frequency and damping factor, depend not only on the geometry of the structure but also on the structural system. Various methods were used for estimating the design wind load. In many cases, however, the gust effect factor approach has been used, particularly since the AIJ Recommendations for Loads on Buildings were revised in 1993 and the specification of gust effect factor was provided for beams supporting flat roofs.

ANALYSIS OF STEELSTRUCTURE FREAME WITH ELASTIC-HIGE JOINT SYSTEM

Sachi FURUKAWA, Motohiko YAMADA, Akihiko OBATA

Journal of Structural Engineering, AIJ, Vol.51B, pp.351-357, 2005.3

 

ABSTRACT: A new joint system named elastic-hinge joint system by the authors is proposed. This new joint system performs in a non-linear elastic restoring force-rotation relation and can materialize origin-oriented frames. These abilities can control damage and reduce permanent structural distortion in structures or in structural elements after a sever earthquake. This paper describes Linked-Element Method as new analysis method for steel structure frames with this new joint. Analysis using this new method is performed on 4-story, 3-bay steel frame with elastic-hinge joints under linear static load. The results indicates that the performance of steel structure frames with elastic-hinge joints under static load can exceed that of the frames with conventional joint systems for steel structures.
