某超高层建筑风位移角控制

Control of the Wind Displacement Angle for a Super High Rise Structure

通过对某超高层建筑进行了风振作用下层间位移角的动力分析和结构的有害层间位移角分析,结合了文献[5]中所提出的允许放松层间位移角限值的相关条件,对该结构进行了适当放宽风荷载作用下的层间位移角限值。并进行了中、大震抗震性能设计,确保地震作用下弹塑性层间位移角满足现行规范要求。对同类工程具有借鉴及参考意义。

Based on the dynamic analysis of maximum layer displacement angle of a super high rise structure under the action of wind-induced vibration and the analysis of adverse structural layer displacement angle, the wind in- duced maximum layer displacement angle of a certain super high rise structure is allowed to relax, which is consis- tent with the corresponding conditions given in Reference [5] . The performance-based seismic design of structure under the action of medium and large earthquakes is carefully analyzed to ensure that the elastic-plastic layer dis- placement angle of this structure under the action of earthquake can meet the existing code requirements. The pro- posed design method can be useful to provide reference for similar projects.
