Abstract : Wind pressure coefficients for
designing open-topped oil storage tanks are investigated based
on a series of wind tunnel experiments. Wind pressures on the
external and internal surfaces of a tank model are measured
simultaneously at many points in a turbulent boundary layer. The
time-space correlations of wind pressures are discussed,
focusing on the characteristics of the internal pressures.

Abstract : Hyperbolic paraboloid (HP)
free-roofs are often used for structures providing shade and
weather protection in public spaces. However, there are few
studies of the wind loads on such roofs. The purpose of the
present study is to investigate the characteristics of the wind
forces and moments acting on HP free-roofs in a wind tunnel. The
overall wind forces and moments are measured by using a force
balance that was designed, built and gauged for the purpose of
the present study. Based on the results, wind force coefficients
for the design of main wind force resisting systems are
proposed.

Abstract : T he dynamic response of a
floating roof in a cylindrical liquid storage tank under wind
loads is investigated analytically. Wind tunnel test in a
turbulent boundary layer is carried out to measure the wind
pressure distributing over the roof surface. The measured data
for the wind pressure is then utilized to predict the dynamic
response of the floating roof, which is idealized herein as an
isotropic elastic plate of uniform stiffness and mass. The
dynamic interaction between the liquid and the floating roof is
taken into account exactly in numerical sense within the
framework of linear potential theory. The numerical results are
presented, which illustrate the significant effect of wind loads
on the dynamic response of liquid-floating-roof system in a
storage tank.

• Wind pressure loading cycles for evaluating
the wind resistance of mechanically attached waterproofing
systems on flat roofs

Wind Engineering, July 19-23, 2009 , Florence , Italy (CD-ROM)
Abstract : Recently, mechanically attached
single-ply roofing has become popular for flat-roofed buildings
in Japan. The roof membrane is either welded or glued to
circular disks, which are arranged in a grid pattern and
mechanically fastened to the roof deck by screws. The fastener
spacing ranges from 0.45 to 0.6 m, depending on the roof zone.
High suctions are induced in the corner and edge zones by the
generation of conical vortices in oblique winds. Fluctuating
pressures may cause fatigue damage to the fixation elements.
When designing such roofing systems, it is important to evaluate
the dynamic effects of wind loading appropriately. Furthermore,
flat roofs generally have parapets, which affect the roof
pressures significantly. Many researchers have studied the
effect of parapets on the peak pressure coefficients. However,
few studies have been made of the effect on the fatigue-related
characteristics of wind pressures so far.
The present paper first outlines a fatigue test on a
mechanically attached single-ply roofing system commonly used in
Japan , and then describes the characteristics of fluctuating
wind pressures on flat roofs with parapets, based on a series of
wind tunnel experiments. A discussion is made of the wind
pressure loading cycles for evaluating the wind resistance of
the waterproofing system. A wind pressure loading cycle model,
named ‘TS-WiLMARS' ( T ohoku University and S umitomo Bakelite ?
W ind L oad Model for M echanically A ttached R oofing S
ystems), is proposed.

Abstract : Wind loads on pipe-framed
greenhouses can be reduced by making the sidewalls porous. Wind
pressures on the external and internal surfaces of two 1:40
scale models of pipe-framed greenhouses with porous sidewalls
are measured simultaneously at many points in a turbulent
boundary layer simulating natural winds over typical
open-country exposure for various wind directions. Wind speeds
at some points inside the greenhouse are also measured. The
porosity of the windward and leeward sidewalls is changed over a
wide range. The wind loads represented by equivalent static wind
force coefficients are evaluated by using the LRC (Load Response
Correlation) method, in which the bending moment at the windward
column base is taken into account as the most important load
effect.
The effects of the porosity on the wind loads and responses of
the frame as well as on the wind speeds inside the greenhouse
are investigated. The results indicate that the porosity of 0.3
? 0.5 can reduce the maximum bending moment by 15 to 20
percents. In such a case, the wind speed becomes approximately
40 percents of the outside wind speed.
Finally, the subjects to be investigated for applying the
results of the present study to practical structures are
summarized.

Abstract : In this paper, we have obtained
wind force coefficients acting on a membrane roof by the wind
tunnel experiment technique and a numerical analysis technique
for free-standing canopy with mesh membrane, and will show one
consideration on an approach of the numerical analysis to get
wind pressure distributions by comparing values of the wind
force coefficients that obtained with these techniques. The roof
type treated in the paper is a mono-sloped roof. The mesh
membrane is porous on the surface, so air of the wind can go
through it. This phenomenon affects the wind force coefficients,
and this point is a characteristic of mesh membrane. Therefore,
it is necessary to reflect this phenomenon on the surface of a
model using in the wind tunnel experiment. For the reason, a
coefficient on wind pressure loss of the mesh membrane to be
called the loss coefficient was actually measured by an
experiment, and was reflected the roof model. Furthermore, this
loss coefficient was used at the analysis. The measurement
experiment to obtain this pressure loss coefficient will be
introduced also.

Abstract : Wind pressures acting on the
external and internal surfaces of a 1:40 scale model of
pipe-framed greenhouse with porous sidewalls are measured
simultaneously at many points in a turbulent boundary layer.
Wind speeds at several points outside and inside the greenhouse
model are also measured. The porosity of the sidewalls is
changed over a wide range. The equivalent static wind force
coefficients generating the maximum peak response are evaluated
by using the LRC (Load Response Correlation) method, in which
the bending moment developed in the frame at the windward column
base is regarded as the most important load effect. The effects
of porosity on the wind-induced response of the frame as well as
on the wind speeds inside the greenhouse are discussed. The
results indicate that the porosity of approximately 0.5 can
reduce the maximum bending moment by approximately 20 percent
without a significant increase in wind speed inside the
greenhouse.

Abstract : The present paper discusses the
wind force coefficients for designing the main wind force
resisting system of a hyperbolic paraboloid (H.P.) free roof,
based on a wind tunnel experiment. In the experiment, the lift
coefficient (C L ) and the aerodynamic moment
coefficients ( C Mx and C My ) about two
horizontal axes ( x and y ) were measured
by using a force balance that had been designed, built and
gauged for the purpose of the present study. Correlations
between wind force and moment coefficients are investigated, and
appropriate wind force coefficients for the design of main wind
force resisting systems are proposed for two wind directions
perpendicular to each other. The roof is assumed rigid and
simply supported by four corner columns, whose axial forces are
regarded as the most important load effect for discussing 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.
The proposed values are compared with the specifications of the
Australia/New Zealand Standard from the viewpoint of load
effect.

ABSTRACT: A new joint system named
‘elastic-hinge joint system' is proposed. This system shows a
non-linear elastic restoring force-rotation relation and can
realize origin-oriented frames. These properties can control
damage and reduce permanent distortion in structures or in
structural elements after a severe earthquake. This paper
describes experimental results on a beam-column connection to
which this joint system is applied. The purpose of this paper is
to clarify the separation and rotation behavior of the elastic
hinge joint. Based on the results, a theoretical model of this
joint system is proposed.

Abstract : The present paper proposes the
external wind pressure coefficients for designing the main wind
force resisting systems of pipe-framed greenhouses widely used
in Japan, based on a series of wind tunnel experiments.
Simultaneous pressure measurements are made with a 1:40 scale
model of the greenhouse in a turbulent boundary layer simulating
the natural winds over typical open-country exposure. The
distribution of the equivalent static pressure coefficients
generating the maximum load effect on the frame are computed by
using the LRC (Load Response Correlation) method; the bending
moment at the windward column base is taken as the most critical
load effect in the analysis. First, a model of the external wind
pressure coefficient is provided for the isolated model. Then,
the effect of adjacent structures on the pressure distribution
is investigated using two or three identical models arranged in
parallel. The results indicate that the proposed model of
external wind pressure coefficients can be applied reasonably to
the plural model cases.
