Abstract
En 中文
Wind loads and earthquakes are assumed to be uncorrelated in earthquake-prone areas; therefore, their interaction is ignored by existing design guidelines. However, the fact that strong earthquake events are commonly followed by strong to moderate aftershocks, and that wind is constantly flowing at high speeds, increases the probability of their joint occurrence, thus making current structural design assumptions questionable. This paper investigates the effect of the combined action of strong winds and vertical and horizontal earthquakes on the seismic response of reinforced concrete (RC) structures. Three reinforced concrete buildings that are representative of low-, medium- and high-rise buildings were analyzed in the nonlinear range using a lumped mass and distributed mass model. It is concluded that the effects of wind load and the vertical component were significant. These effects can significantly affect the axial forces in the columns but do not significantly affect base shears. It is essential to include the combined effect of earthquakes and wind to accurately predict the ductility of the structures and their respective expected failure mechanisms under multi-hazard load conditions.
