| Abstract: | Some techniques of nonlinear dynamic analysis involved in the computer numeric simulation on earthquake performance and damage of R/C structures are discussed briefly, which include the constitution of structural dynamic analysis model, selection of element analysis model and its restoring force model, application of successive integration, revision of unbalanced force, expression for seismic response energy, and the computer programs for nonlinear dynamic analysis. As an example, a simulation of the earthquake response of a real R/C structure is illustrated. |
