“…Field monitoring is the best way to test the wind resistance of building structure, but the high test cost and site environment cause many difficulties in field monitoring [5][6][7][8][9]. Most researchers use pneumatic tests and numerical simulation based on computational fluid dynamics (CFD) to analyze the wind resistance performance of the structures [10][11][12][13].…”

This study focuses on wind resistance of high-rise building structures. Firstly, the monitoring results of wind tunnel test are compared with the numerical simulation results based on CFD to verify the feasibility of the CFD numerical method, and the wind pressure coefficients of full-size structures and multi-type high-rise buildings are analyzed with the CFD algorithm. The results show that the monitoring results based on wind tunnel test and CFD simulation are very similar, and the distribution of the overall wind pressure coefficients is basically the same. As seen in top view and elevation view of wind pressure coefficient contours for full-size building structures, the wind pressure coefficient on the windward side and leeward side of a full-size building is relatively small, and the wind pressure coefficient in the incoming wind side is relatively large, which is because of the influence of Reynolds Number Effect in the area of the incoming wind side, which results in the relatively greater negative pressure on the lateral side of the building. The contour distribution of wind pressure coefficients for different types of buildings is generally similar, indicating that the shape of buildings has basically no effect on the distribution of wind pressure coefficients. This study establishes static pressure field fitting curves for the windward, crosswind, upwind, and leeward directions. The "static pressure corridor" can accurately determine the zero pressure position, and long-term monitoring at the point with zero pressure can achieve the best test results.

This work presents a Computational Fluid Dynamics (CFD) wind flow analysis technique applied to a Parabolic Solar Tracker (PST) using a three-dimensional Reynolds-Averaged Navier-Stokes Method. The modeling technique considered two extreme weather conditions named: (i) North Wind (NW) and (ii) Severe Convective Storms (SCSs), both of which can severely affect the integrity and the position control of a PST under operational conditions. The NW case simulated was validated using experimental data without bottom effects in order to verify the degree of approximation between the numerical results obtained in each approach and measurement data. It was observed that the simulated data were satisfactory in most cases, with predictions on the order of 77% compared to the measured data. The numerical CFD results at different heights for both cases, NW and SCS, were also verified. Finally, the CFD wind flow analysis technique results were used to: (i) establish both analytical and numerical models for dynamic and steady state analysis, control design, and simulation purposes and (ii) consequently design a closed loop controller which can minimize the wind effects.
