Kriging metamodels for the dynamic response of high-rise buildings with outrigger systems and fragility estimates for seismic and wind loads

Abstract

This paper proposes kriging metamodels for the dynamic response of high-rise buildings with outrigger systems subject to seismic and wind loads. Three types of outrigger systems are considered. Three-dimensional (3D) finite element models of high-rise buildings with outrigger systems are developed using ANSYS. Data generated from the finite element models are used to develop the proposed kriging metamodels. A sensitivity analysis is then carried out to determine the most sensitive input parameters in kriging metamodels to gain insights and suggest possible future developments. The proposed kriging metamodels are used to develop fragility estimates for high-rise buildings with three types of outrigger systems under seismic and wind loads.
