TL;DR: In this paper, the authors deal with some recent studies on numerical and analytical models for the evaluation of aeroelastic response of cross-section models of long span bridges, and select the time-domain indicial approach, whose validity has been only partially investigated in the past, for the modeling of self-excited forces.

TL;DR: In this article, Chen et al. performed lateral correlation analyses on two sets of full-scale thunderstorm downburst full wind speed time series and found that the two lateral profiles are fully correlated and almost evenly spatially distributed in the largest and medium scales with more than 96% of the total energy.

TL;DR: Papadopoulos et al. as discussed by the authors used a wind tunnel model aiming to simulate the thermal effects within the vicinity of a building with leeward wall heating, which was used as input data for generating typical weather data required as input for building and heating, ventilation and air-conditioning (HVAC) system models.

TL;DR: In this article, the authors investigated the moving stability of a vehicle under seismic motion based on both numerical simulation and virtual experiments using a driving simulator, and the results obtained from the numerical and experimental studies are compared and the validity of the driver model is discussed.

TL;DR: In this article, a series of parametric wind tunnel studies were conducted at BRE to measure wind pressures on a wide range of curved roof models in a properly scaled atmospheric boundary layer simulation and gave an alternative to the EN1991-1-4 recommended procedure.

TL;DR: In this article, five ultrasonic anemometers are used to measure flow velocities above the roof of a 6 m cube and at a reference point upstream, and various analysis techniques are applied to the data in order to illustrate the differences between: the mean reattachment position when the mean wind is normal to the windward face (0°), which is at x/h≈0.6; the median instantaneous reattach position at x / h = 0.6 6 6 and the position that would occur if the wind direction was held at a constant
