A study on the wind-induced vibration response material characteristics of typical and atypical high-rise buildings according to changes in corner shapes material

摘要

High-rise buildings have very slender, atypical, and lightweight shapes such that the higher they become, the more flexible they are, and it is very important to review closely the structure behavior, stability, and usability when designing ultrahigh-rise buildings with a great influence from dynamic load. Accordingly, the wind-induced vibration characteristics according to shapes and edge shape changes were experimented. The wind load spectrum, basic type showed the greatest peak value, but the corner cut reduced the magnitude of the peak. The maximum displacement response was slightly reduced in the across-wind direction and greatly reduced in the along-wind direction for A-type. For B-type, the across-wind direction showed a distribution similar to that of the corner cut model, and the along-wind direction saw similar reductions in the basic model and corner cut. The maximum displacement response value was found to be B>A(type) for across-wind direction and A >B(type) for along-wind direction.
