A SIMPLE METHOD TO CALCULATE THE EQUIVALENT STATIC WIND LOAD ON LOW-RISE BUILDINGS

The wind-induced dynamic response of low-rise building is dominated by the non-resonant component. The gust loading factor method, fitted for resonant response dominating cases, is not suitable for low-rise buildings. And Load-Response-Correlation (LRC) method has difficulty in practical application due to some deficiencies such as sensitivity to the response positions and types. A Load-Lift-Correlation (LLC) method is proposed, which aims at the maximal or minimal lift force. The theory and the corresponding calculation steps are given. The equivalent static wind load calculated by LLC method is the dynamic wind load if the wind pressures are fully correlated. Therefore, the LLC method unifies the wind load equations for main structure design and shielding system design. Two examples are given to verify the rationality of LLC method in obtaining the equivalent static wind load on low-rise buildings.
