实际工程中可通过减小结构所受的外扭矩与提高结构的抗扭刚度来控制高层建筑结构的扭转效应。

The torsion effect of tall building structures can be controlled by decreasing the moment of torsion and increasing the structural torsion stiffness in practice engineering.

结果表明：在较宽的地震波频带内，两种阻尼器对于控制这一不规则结构的扭转效应，提高该结构的整体抗震性能均有较好的减震效果。

Then, the dynamic response of the uncontrolled structure and controlled structure are intestigated under the excitation of earthquake from three aspects of energy, displacement and force.

“高规”通过扭转周期比和扭转位移比双重控制指标对结构扭转效应进行控制。

JGJ3-2002 controls the structural torsional effect with torsional period ratio and torsional displacement ratio these two indexes.
