由某设计实例看周期比对结构扭转的影响
From the design of an office building to find out the essentiality of period ratio
论述了高规中“对A级高层建筑以扭转为主的第一振型周期和以平动为主的第一振型周期比值不大于0.9”要求的基本意义，并对一工程实例采用push-over方法预测了不满足周期比要求时在地震荷载作用下可能发生的破坏形式，说明了重视周期比限值的重要性。
issertate the ultimate principle of “restricting the ratio of the first torsional vibration period to the first translational vibration not exceed 0.9 to A tall building structure” in the Technical Specification for concrete structures of tall building (JGJ3-2002).Point out the essentiality of period ratio using push-over analysis to an instance for forecasting what would happen under earthquake action when the building can not restrict the period ratio.
