PREDICTION OF SHEAR CONTRIBUTION OF WALLS IN RC WALL-FRAME BUILDINGS UNDER EARTHQUAKE MOTIONS
This paper shows two earthquake response evaluation methods for multi-story wall-frame buildings. One is a method of redistributing the representative shear in an equivalent SDOF system reduced from the wall-frame building to the first mode components of the story shears contributed by the shear walls and frames, and the other is a method of evaluating the higher mode components of the story shears. Time history earthquake response analysis and pushover analysis for three types of 12 story RC wall-frame building with different wall layouts are performed to examine the prediction accuracy of earthquake responses by the proposed methods. Good agreements between the results of the proposed methods and the earthquake response analysis are obtained in terms of the story shears contributed by the shear walls and frames.
