In addition, when the overall damping is increased to a certain level, some modes will become over-damped. In such cases, the conventional treatment by using the classical damping assumption (ignoring the non-classical damping effect and the over-damped modes) may result in unacceptable design errors on the unsafe side. Based on the general modal response history analysis formulation with over-damped modes developed by the authors (Song et al. 2008), this paper further extends it to a response-spectrum analysis approach and proposes a general modal combination rule GCQC. Examples to examine the accuracy and effectiveness of this approach are also given.
