Wind-induced motions of a multi-storey building in serviceability limit state
In this preliminary study, comfort condition of a medium-rise building due to wind induced vibration is assessed according to three international design codes, that is: EN 1991-1-4, AIJ recommendations and AS/NZS 1170.2. A conceptual concrete reinforced building located in the capital area of Icelan...

In this preliminary study, comfort condition of a medium-rise building due to wind induced vibration is assessed according to three international design codes, that is: EN 1991-1-4, AIJ recommendations and AS/NZS 1170.2. A conceptual concrete reinforced building located in the capital area of Iceland is considered. The building has 22 storeys, height of 80 m and width and depth of 36 m and 18 m respectively. Various parameters determine the dynamic response of the building in terms of peak acceleration such as number of storeys, side ratio of a building, stiffness and mass distribution, damping ratio, as well as parameters that control the wind intensity and characteristic. The along-wind acceleration response is evaluated according to all three code-based approaches but only the AIJ recommendations and AS/NZS 1170.2 provide methods to evaluate the across-wind response. EN 1991-1-4 gives the largest estimated along-wind response for fixed damping ratio when wind acts on either side of the building. Some discrepancy is observed between the codes for the across-wind response when wind acts normal to the long-side of the building. It is determined that the across-wind response of the building is higher than the along-wind response for wind that acts normal to the short-side of the building and exceed the human comfort limits proposed by ISO 10137 and the AIJ guidelines for terrain category II as defined in EN 1991-4.
