Abstract : More than two identical
pipe‐framed greenhouses (referred to as “pipe houses” hereafter)
are often arranged in parallel. The wind pressure distributions
on the pipe houses are significantly affected by the distance dp
between them. This article investigates the effect of dp on the
distribution of wind pressure coefficients Cp on two or three
pipe houses arranged in parallel, based on a wind tunnel
experiment using 1:20 scale models of a typical pipe house.
Focus was on a wind direction perpendicular to the ridgeline.
The distance dp varied from 0.25H to 6H, with H being the ridge
height of the pipe house. The results indicate that the Cp
distribution on the windward side of the first pipe house was
similar to that for an isolated pipe house, while the Cp values
on the roof and leeward wall were dependent on dp. On the other
hand, the Cp values on the second and third pipe houses were
generally negative and significantly affected by dp, in
particular on the windward wall and roof. Very high suctions
were induced on the leeward roof of the second pipe house near
the ridge when the distance dp was small. The suctions may be
induced by the second separation of the reattached flow on the
windward roof at the location of the ridge. The local drag and
lift coefficients, CD and CL, on the central cross‐section were
also computed from the Cp distribution. The influence of the
adjacent pipe houses on the CD was significant, while the CL was
less sensitive to dp.

ABSTRACT : The present paper discusses the design wind loads
on cylindrical storage tanks, such as oil-storage tanks, based
on a series of wind tunnel experiments together with a
theoretical analysis of wind-induced buckling. Focus is on
open-topped tanks; the effects of roof on the wind forces as
well as on the buckling behavior are investigated. In the wind
tunnel experiments, the wind pressures are first measured at
many points both on the external and internal surfaces of rigid
models in a turbulent boundary layer. Then, the pre-buckling and
buckling behavior of thin cylindrical shells is measured in
smooth and turbulent flows. A discussion is made of the dynamic
load effects of wind pressures on the buckling behavior. A
theoretical analysis of the buckling under static wind loading
is conducted based on Donnell Theory. The effect of wind force
distribution on the buckling behavior is investigated. The
results indicate that the wind force distribution on the
windward surface affects the buckling behavior significantly.

A New Model for Estimating Wind-induced Responses of
Tall Buildings with Consideration of Cross-term between
Background and Resonant Components

pp.117-126 , 2010.10
ABSTRACT : In current design practice, the
responses of buildings and structures to fluctuating wind loads
are usually separated into the background and resonant
components, based on the assumption that these two components
are not correlated with each other. The present paper proposes a
new model for estimating the wind-induced responses of tall
buildings, in which the background and resonant components and
their cross-term are strictly defined and included. Therefore,
the new model is more exact than the conventional ones.
Comparisons are made for the along-wind and across-wind
responses of tall buildings between this model and the
conventional ones, based on a parametric investigation. The
results show that the conventional models give results similar
to those obtained from the new model for the along-wind
responses, but generally underestimate the across-wind
responses. Finally, some conclusions and useful suggestions are
presented.

is on open-topped tanks; the effects of roof on the wind forces
as well as on the buckling behavior are investigated. In the

behavior of thin cylindrical shells with or without roof is

effect of wind force distribution on the buckling behavior is
investigated. The results indicate that the distribution on the
windward surface affects the buckling behavior significantly.

ABSTRACT : The purpose of the present paper
is to discuss the wind force coefficients of a hyperbolic
paraboloid (called ‘HP', hereinafter) free roof for the design
of membrane strictures, based on a wind tunnel experiment 1) as
well as on a CFD (Computational Fluid Dynamics) analysis. We
investigate the validity of analytical approach 2) to obtain the
design wind force coefficients. In the present paper, the lift
coefficient ( C L ) and the aerodynamic
moment coefficients ( C Mx and C My
) about two axes ( x and y ) are
obtained. Correlation between the wind force and moment
coefficients are investigated, and appropriate wind force
coefficients are proposed for two wind direction perpendicular
to each other. In the discussion of the design wind force
coefficients, the roof is assumed rigid and simply supported by
four corner columns, and the axial forces induced in the columns
are regarded as the most important load effect for estimating
the design wind loads. Two load cases generating the maximum
tension and compression of columns are considered. The roof is
divided into the windward and leeward halves for each wind
direction, and the wind force coefficients on these halves are
provided. Finally, the proposed values are compared with the
specifications of the Australia/New Zealand Standard 3) from the
viewpoint of load effect. A comparison of the results on the
wind force and moment coefficients between wind tunnel
experiment and CFD analysis indicates a potentiality of the CFD
analysis for evaluating the wind forces on HP free roofs with
various shapes, although some improvements should be made.

ABSTRACT : The Building Standard Law of
Japan and Recommendations for Loads on Buildings have no design
pressure and force coefficients for hip roofs and eaves. In
order to investigate these pressure and force coefficients for
low-rise buildings (dwelling house), a series of boundary layer
wind tunnel tests was executed by six organizations as a part of
the committee activity consigned by the Ministry of Land,
Infrastructure, Transport and Tourism. In the series of wind
tunnel tests, wind pressures on gable roofs and hip roofs were
evaluated with four roof-angles and two overhanging depths of
eaves, including cases without eaves and flat roofs. As the test
results, the peak pressure coefficients of roof surface and peak
force coefficients of eaves/peak pressure coefficients of back
eaves for facade design were mainly discussed in this paper.

ABSTRACT : Pipe-framed
greenhouses are often subjected to wind-induced damage. This may
be due to a fact that the wind force coefficients for designing
such greenhouses are not specified in codes and standards. The
present paper first shows some typical wind-induced damage to
greenhouses. Then, a discussion is made of the external pressure
coefficients for designing the structural frames and
cladding/components of pipe-framed greenhouses, based on a wind
tunnel experiment. For discussing the wind pressure coefficients
for the structural frames, focus is on the bending moment at the
windward column base as the most important load effect. The LRC
method is employed. A model of the wind pressure coefficient
distribution is proposed. On the other hand, focus is on the
area-averaged peak wind pressures, when discussing the design
wind pressures for cladding/components

behavior significantly.

ABSTRACT : A model for
evaluating the equivalent static wind loads (ESWLs) on
base-isolated buildings under fluctuating wind loads is proposed
in the frequency domain, with an assumption that the response of
the isolators (isolation elements) is within the pre-yielding
(linear) range. The natural period and damping of such buildings
are discussed based on some parametric investigations. This
model conveniently adopts the wind spectra for conventional tall
buildings obtained from codes or wind tunnel experiments to
evaluate exactly the ESWLs on base-isolated buildings. Finally,
some numerical examples are presented for the along-wind and
across-wind ESWLs on a tall base-isolated building.

ABSTRACT : In the previous
study, the authors proposed a novel beam-column joint system, or
an elastic hinge joint system. This joint system exhibits a
self-centering behavior; that is, it has a nonlinear hysteresis
character of force-rotation restoration. Steel structural frames
with such a joint system can be used to control the structural
damage as well as to reduce the residual strain after severe
earthquakes. The objective of the resent study is to investigate
the response of steel structural frame with the proposed elastic
hinge joint system to earthquakes, based on a substructure
pseudo-dynamic test. The results show a nonlinear elastic
hysteresis character of the relation between moment and rotation
angle at the joint, as a theoretical model predicts. The maximum
shear force and acceleration at each story of the structure
induced by earthquakes are both reduced by such a behavior of
the joint system.
