Development of drift design model for high-rise buildings subjected to lateral and vertical loads

Recent developments of resizing algorithms based on displacement participation factor have had a significant impact on drift design of high-rise buildings. However, most drift design methods based on resizing algorithms have considered only lateral load and overlooked the effect of the vertical load in the calculation of member displacement participation factors. Therefore, in this paper, the practical drift design method of high-rise buildings is presented in the form of a resizing algorithm by developing product integral modules required for the calculation of displacement participation factors with the consideration of both lateral and vertical loads. The effect of vertical load on the drift design model based on member displacement participation factors is investigated in detail using the verifying example of a 20-story building structure. The drift design method in combination with the strength design module is then applied to the drift design of a 60-story high-rise building structure.
