a b s t r a c tIn current practice, structural engineers commonly focus on the wind-resistant design by means of static wind loads. In the case of non-Gaussianities, there is room for improvement to properly derive these static loads. First, this paper extends in a non-Gaussian context the concept of the load-response correlation (LRC) method establishing equivalent static wind loads (ESWLs). This is done by a proper recourse to the new concept of conditional expected static wind load and a proposed bicubic model for the joint and conditional distribution functions. Second, this paper investigates the envelope reconstruction problem targeting the efficient reconstruction of the envelope values of a set of non-Gaussian structural responses by means of principal static wind loads (PSWLs). They have been introduced in a Gaussian context and are obtained by a singular value decomposition of ESWLs. This paper addresses the extension of PSWLs to non-Gaussian structural responses, as well. The developments apply to structures with a linear behavior and subjected to an aerodynamic pressure field exhibiting mildly to strongly nonGaussian features. In this context, the well-known load-response correlation and conditional sampling methods are used for comparisons. This study is undertaken for quasi-static analysis of structures and is illustrated on a low-rise building.

“…It must be remarked that the lowturbulence testing condition can be considered a more severe condition than turbulent flow (Kawai, 1997;Suzuki et al, 2003;Tieleman, 2003), and the correlation with full-scale measurements is better when comparing average wind loads than when comparing peak wind loads (Ahmad and Kumar, 2001;Ho et al, 2005). No blockage corrections of the measured results has been considered, as even in the worst case the normal-to-wind areas of the testing models were smaller than 8% of the wind tunnel crosssection.…”

The effect of an upstream building on the suction forces on the flat roof of a low-rise building placed in the wake of the former is analyzed. The analysis has been performed by wind tunnel testing of a flat roof, low-rise building model equipped with pressure taps on the roof and different block-type buildings (only configurations where the upstream building is as high or higher than the downstream one are considered in this paper). The influence of the distance between both buildings on the wind loads on the downstream building roof is analyzed, as well as the height of the upstream one and the wind angle of incidence. Experimental results reveal that the wind load increases as the relative height of the upstream building increases, the wind load being highest for intermediate distances between buildings, when a passage between them is formed.

“…Although some previous studies (Holmes [4]; Ho etal. [5]; Sharma and Richards [6]; James et al [7]; Joachim et al [8]) have shown that wind pressure in a building can be affected by partial opening, and there are not many works on wind-induced response of high-rise buildings with partial opening. In recent years, the use of wind power (Bayoumi et al [9]; Lu and Sun [10]) has become as one of the most interesting research topics.…”

Abstract-The paper discusses the wind pressure distributions on high-rice buildings with partial openings by means of wind tunnel tests and numerical simulations. The wind tunnel tests were carried out in the boundary layer wind tunnel over an urban terrain with a geometric scale. The numerical simulations used the method of S IMPLEC algorithm and the turbulence model, in which a realizable κ-ε model was used to simulate the pressure coefficient and the wind environment surrounding the partial openings. Detailed analyses of wind pressure coefficients for buildings of three different opening cases are presented. The results show that the pressure coefficients are different on the two sides of the opening and the distribution of wind velocity surrounding the opening is remarkably affected by the opening size. Moreover, the wind speed reaches the maximum in the opening when the wind direction is 45°. This suggests that there is a potential to utilize the wind energy by placing wind turbines in the partial opening of the high-rise buildings.
