摘　　要：针对精细时程积分法在大型结构地震响应分析中的应用,提出振型分解精细时程积分法以及精细积分法与Newmark-β法的耦合方法,并应用于结构在地震作用下的反应。算例表明,精细积分法、振型分解精细积分法及耦合方法对于地震作用这样的复杂荷载有很好的适应性,可以在工程中推广应用。To aim at application of precise time integration method in the earthquake response analysis of large-scale structures, two new time integration methods are presented in this paper. One is called mode decomposition precise integration method because it is the result of the combination of mode decomposition method with the precise integration method. The other is a coupling method which is result of coupling the precise integration method with the well-known Newmark-β method. Numerical examples show that the two new coupling methods and precise integration method are effective in the structural earthquake response analysis of large-scale structures.
