The barrel shape structure work like an overhanging beam and when subjected to earthquake load, its dynamic stress of outer frame is greater than that of inner tube.

超高层筒体结构近似悬臂梁弯曲受力构件，在动力作用下，外框剪力墙的动应力反应要大于核心筒墙的动应力反应。

It includes the single site damage detection of continuous beam, simple support beam, fixed end beam, overhanging beam, truss, and the multipoint damage detection of simple support beam.

本文采用了连续梁、简支梁、固端梁、悬臂梁、桁架等的单点损伤识别，简支梁的多点损伤识别。
