For structures with non-proportional damping, complex eigenvectors or mode shapes must be used in order to decouple the equations of motion. The resulting equations can then be solved in a systematic way. The necessity of solving a complex eigenvalue problem of a large system remains an obstacle for

In stochastic analysis the knowledge of cross-correlation coe$cients is required in order to combine the response of the modal Single-Degree-Of-Freedom (SDOF) oscillators for obtaining the nodal response. Moreover these coe$cients play a fundamental role in the seismic analysis of structures when th

The step-by-step modal time history integration methods are developed for dynamic analysis of non-classically damped linear structures subjected to earthquake-induced ground motions. Both the mode displacement and mode accelerationbased algorithms are presented for the calculation of member and acce
