Tall buildings are very sensitive to wind-induced excitation. Currently, in the design of structures, the wind-induced loading is commonly estimated based on the models available for synoptic events. However, in many parts of the world, thunderstorms tend to dominate the local wind climate. Thunderstorm downbursts differ from synoptic events due to their nose-shaped mean wind speed profile and non-stationary behavior over short intervals (10 min to 1 h). Wind tunnel testing is an effective method for analyzing wind effects on structures. However, simulating thunderstorms in traditional facilities requires specialized equipment. Disregarding the non-stationary characteristics of thunderstorm outflows, ERIES-TLTB Project focuses on the wind-induced effects on tall buildings caused by thunderstorms and synoptic events, focusing on the impact of the variation of the mean wind speed profile. Experimental tests are conducted using high-frequency force balance and pressure integration techniques on different tall building models. A comparison of the pressure coefficient distribution is provided for the two types of events.
