The Investigation of Structural Behavior with Variations in the Lower Stories of Complex Buildings using Push-over Analysis

Push-over 해석을 사용한 복합구조물의 하부골조 층수변화에 따른 거동분석

Upper wall-lower frame(complex building) can be divided into three partition, namely, upper wall, lower frame, and transfer system which link two partitions. The purpose of this study is to investigate the elasto-plastic response characteristics of structures with variation in the stories of lower frame of complex buildings. The conclusions of this study was following; 1) In the push-over analysis for vertically irregular building, the distribution of lateral forces is judged which consider the effects of higher mode. 2) In proportion as the stories of lower frame increase inter-story displacement of lower frame increased, but that of upper wall decreased. 3) The appearance of yielding hinge with variations in the lower stories of complex buildings differed in lower frame of each model, but was almost the same in upper wall.
