Comparison of different calculation methods and models for mixed core-frame structural system

Paper presents different calculation methods for lateral load analysis of mixed reinforced concrete core and frame structural systems in tall buildings. Presented calculation methods include approximate analytical methods, based on closed-form solution of differential equations, and numerical finite element models. Example tall building comprises of peripheral rigid frames and partially closed inner core with uni-symmetric arrangement in plan and constant properties along the height. Deflection and rotation results obtained by the analysis are plotted comparatively. Conclusion is derived from results and accuracy analysis.
