Dynamic Response Analysis of Reinforced Concrete Frame Using a Three-Element-Maxwell Model

Dynamic analysis of structures with Maxwell model

“…They treated the Maxwell model as a supplementary restoring force on the equation of motion of the system discretized by a central di!erence method, which is categorized into an explicit integration scheme. Similarly, on the response analysis of a reinforced concrete frame structure including the Maxwell model, Fujimoto et al [14] have reported a computational method in which a restoring force of the Maxwell model is substituted by an equivalent tangent sti!ness and a correction force through the convergence calculation process, and those equivalent variables are introduced into the equation of motion discretized by Newmark's method. Among the examples in this approach, on the analysis of the stress}strain relationship of a visco-elastic body, restoring force of the Maxwell model is incorporated into the incremental form of the equation of motion based on the "nite element method [15}19].…”
