| Abstract: | Torsional and lateral vibration of a high-rise building with L shape plan under earthquake will couple because of large distance between center of stiffness and center of mass. Main factors to enlarge the torsional response induced by coupling action are analysed. The countermeasures to reduce the torsional effect are provided through the examples. |

| Keywords: | L shape plan high-rise building couple torsional effect |
