New Nonlinear Modal Decomposition Method for Seismic Analysis of Tall RC Core Wall Buildings
Significant research has been conducted in the past to develop simplified seismic evaluation procedures for tall buildings. However, most of these procedures are based on the use of fundamental mode response while ignoring the responses from higher modes. Moreover, such seismic evaluation procedures are unable to accurately predict individual-member responses. Evaluation of individual-member responses is an important part of damage and loss prediction estimation due to seismic hazard. In this research work, a new nonlinear modal decomposition approach is proposed for seismic evaluation of tall RC core wall buildings that can take into account the higher mode effects. This procedure is an extension of the classical Uncoupled Modal Response History Analysis procedure. A 44-story reinforced concrete core wall building is selected to verify the accuracy of the proposed procedure. A comparison between the outcomes of the proposed procedure and the nonlinear response history analysis procedure shows that this procedure is reasonably accurate in predicting important global and member responses.
