摘要
从分析结构周期与顶点位移、层间位移角的关系出发,论证了控制结构最大层间位移角实际上就隐含控制了相应结构的平动周期值,确定了高层建筑的最大层间位移角限值就没有必要再另行控制结构的平动周期。论述了结构抗扭设计的三个核心问题,分析了单一控制扭转周期比存在的问题。
Based on analysis of the relationship between structure period, top displacement and story drift, it was testifies that controlling the maximum story drift actually control the translational basic period value of the structure implicitly. So it is not necessary to control the translational basic period value of the structure if the maximum story drift limit value of the high-rise building is certain. Three key problems on torsional design of the structure were also discussed and some questions in controlling simply torsional period ratio were analyzed.
