Abstract

A new predictor-corrector (P-C) method for multi-site sub-structure pseudo-dynamic (PSD) test is proposed. This method is a mixed time integration method in which computational components separable from experimental components are solved by implicit time integration method (Newmark β method). The experiments are performed quasi-statically based on explicit prediction of displacement. The proposed P-C method has an important advantage as it does not require the determination of the initial stiffness values of experimental components and is thus suitable for representing elastic and inelastic systems. A parameter relating to quality of displacement prediction at boundaries nodes is introduced. This parameter is determined such that P-C method can be applicable to many practical problems. Error-propagation characteristics of P-C method are also presented. A series of examples including linear and non-linear soil-foundation-structure interaction problem demonstrate the performance of the proposed method.
