Traditional nonlinear static and dynamic analyses do not accurately estimate the energy dissipation capacity of reinforced concrete structure.
Recently, simple equations which can accurately calculate the energy dissipation capacity of flexure-dominated RC members, were developed
in the companion study. In the present study, nonlinear static and dynamic analytical methods improved using the energy-evaluation method
were developed. For nonlinear static analysis, the Capacity Spectrum Method was improved by using the energy-spectrum curve newly
developed. For nonlinear dynamic analysis, a simplified energy-based cyclic model of reinforced concrete member was developed. Unlike the
existing cyclic models which are the stiffness-based models, the proposed cyclic model can accurately estimate the energy dissipating during
complete load-cycles. The procedure of the proposed methods was established and the computer program incorporating the analytical method
was developed. The proposed analytical methods can estimate accurately the energy dissipation capacity varying with the design parameters
such as shape of cross-section, reinforcement ratio and arrangement, and can address the effect of the energy dissipation capacity on the
structural performance under earthquake load.
