Abstract

The nonlinear response of civil structures is often characterized by the phenomenon of hysteresis. The ongoing research effort in relevant topics has been generating scores of analytical descriptions corresponding to a number of nonlinear hysteretic systems. Nevertheless, many conventional time integration procedures associated with these descriptions can be arduous. Focusing on a typical description, this paper presents the development of a surrogate model in place of the conventional procedures with the aim of improving the time integration efficiency. In particular, the performance of the surrogate model is demonstrated by studying the nonlinear response of the hysteretic system due to wind loads. Options for further performance improvement of the surrogate model, together with its potential application to safety assessment and health monitoring of structures, are also discussed.
