Development of Drift Design Method of High-rise buildings considering Material Properties of Shear Walls and Design Variable Linking Strategy

RC 전단벽의 재료 물성과 부재 그룹핑을 고려한 고층건물 변위조절설계법 개발

Resizing techniques have been recognized as practical methods for drift design of high-rise building since sensitivity analysis and iterative structural analysis are not required in implementation. In the techniques, the amount of material of a memberin a building for resizing is determined in terms of cross-sectional areas and sectional inertia moments as design variables. In this study, five drift design methods are developed by considering design variable linking strategy and fomulating resizing algorithm in terms of material properties of shear walls as a design variable. The developed methods are applied to the drift design of 20-story frame-RC shear wall structure, and then evaluated in the view points of practicality and efficiency.
