TL;DR: In this paper, an account is given of the measurement of wind pressures on a two-storey housing estate on the outskirts of Aylesbury, 65 km north-west of London.

TL;DR: In this article, surface wind pressure measurements made simultaneously at 32 points on a 57-storey office tower in Toronto are reported, in addition to readings taken at 1 2 -second intervals during high winds, mean and root-mean-square pressures were recorded for a 5-minute interval once each hour, and pressure coefficients referred to the free stream dynamic pressure at 286 m were computed for comparison with wind tunnel test information which was used in the design of the cladding.

TL;DR: In this paper, the effects of varying the scale of turbulence on the mean drag on a range of square prisms has been carried out and sufficient measurements have been made to isolate the differing effects of turbulence intensity variations and turbulence scale variations.

TL;DR: In this article, the results of an experimental study concerning blockage effects on the drag of sharp-edged bodies at Reynolds numbers high enough for viscous effects to be negligible were described.

TL;DR: In this paper, the equations of motion of atmospheric flow over a surface obstruction are formulated in terms of two flow variables, then written in finite difference form and solved numerically subject to specified closure assumptions and boundary conditions.

TL;DR: In this paper, the authors compared full-scale measurements of the mean wind speed and mean wind direction at several points in a plaza located in a built-up urban environment with similar measurements obtained in a scaled boundary layer wind tunnel model study.

TL;DR: In this article, measurements of wind velocity and structure vibration were made on a concrete chimney of 180m height in South Germany, where all data were recorded continuously in an analogue form and the statistical properties of excitation and response, as well as the relationship between these two quantities were determined.

TL;DR: A wind tunnel of open-circuit configuration designed specifically for building aerodynamics is described and its performance is discussed in this paper, where a 3-component traversing mechanism is used to allow remote positioning of probes anywhere within the area.

TL;DR: In this paper, the historical role that full-scale observations have played in the development of engineering approaches to wind effects is discussed, and the pitfalls in neglecting fullscale measurements in developing engineering design procedures are referred to.

TL;DR: In this paper, wind pressure measurements were made on two full-scale natural draught cooling towers, standing in a row of four cooling towers of a power plant, and the fluctuating pressure distribution was analysed in meridian and circumferential directions and the correlation probabilities were presented.

TL;DR: In this paper, the response to wind action of the 151m-high BHP House in Melbourne, Australia, has been measured with an accelerometer at the top floor level.

TL;DR: In this article, the fluctuating components of wind pressures on hyperbolic cooling towers are sensitive to Reynolds number and surface roughness in a similar way to the average pressures and their influence is discussed and a method is given to extract as much information as possible in spite of the disturbing process.

TL;DR: In this paper, the calibration and use of a shielded dual-sensor hot-wire probe, originally developed at McGill University for velocity measurement in highly turbulent and reversing flows, is described.

TL;DR: In this article, the authors measured pressure fluctuations on the windward and leeward faces of a 43m-high building situated in a relatively exposed location and made measurements of velocity fluctuation on the top of the building.

TL;DR: In this paper, the results of measurements on steel chimney stacks are presented, mainly full-scale tests carried out after rebuilding a 145m high and 6m diameter steel stack which collapsed owing to wind-induced vibrations.

TL;DR: In this article, the static reference pressure was found by using the pressure distribution around the cylindrical tower shaft, with the assumption that the zero angle of a pressure distribution is at φ0 = 34° (depending on Reynolds number).

TL;DR: In this article, the authors explain the difficulties experienced by a wind tunnel aerodynamicist when, to assist in its structural analysis, he is asked to conduct an experiment to measure the short term value of pressure at many locations in a building for the complete range of wind directions.

TL;DR: In this paper, a cable-stayed highway bridge across the River Rhine near Speyer was under construction, and full-scale measurements were made to obtain the dynamic characteristics of the pylon and the projecting parts of the bridge.

TL;DR: In this article, the authors describe the 330m-high television tower at Emley Moor, with particular reference to the structural steel cantilevel mast at the top carrying the aerials.

TL;DR: In this article, the dynamic response of manometers was experimentally examined using visual, photographic, peak deflection indicators and a shake table and the observed response frequencies and damping were reasonably consistent with simple theoretical models which accounted for the damping incurred from simple viscous flow.

TL;DR: In this paper, wind velocities at three different heights at the Munich television tower (Olympic tower) were measured at 149 m, 220 m and four cup anemometers are placed around the concrete cylinder.

TL;DR: In this article, the authors present some measurements of the dynamic response of the CN Tower in Toronto, during a partial erection stage, using an instrumented reinforcing bar at the base of the tower with the concrete shaft completed.
