Wind-Induced Response Analysis for High-Rise Buildings Based on Time-Variant Speed Model Considering Climate Change

Year: 2025

Type: article

Abstract: Under the scenario of global climate change, the wind resistance of high-rise buildings is facing a huge challenge. Climate change could cause an increase in wind speed, which poses a greater threat to high-rise buildings. However, the degradation of structural resistance will intensify. The wind-induced response that is based on the traditional standard might be strongly underestimated. Therefore, this study suggests a time-variant speed model that considers climate change, which quantifies the increase in wind speed in the future under different predictive models. Then, the safety and serviceability of a 17-story high-rise building associated with the build, natural aging, and climate change scenarios are compared. The results indicated that the safety and serviceability that correspond to the climate change scenario have a significant decrease compared with natural aging. For the prototype building, wind speed will reach very disturbing levels for residents on floors above the 11th under climate change scenarios, which is only the 15th–17th in the natural aging scenario.
