Abstract |
This study presents an effective stiffness-based optimization technique to control quantitatively lateral drift and to evaluate the structural behavioral characteristics and efficiency for tall outrigger system subject to lateral loads. For this end, displacement sensitivity depending on behavioral characteristics of outrigger system is established and approximation concept that can efficiently solve large scale problems is introduced. Specifically, under the `constant-shape` assumption, the resizing technique of member is developed. Six types of 60 story frameworks according to the location of outrigger and belt truss are presented to illustrate the features of the quantitative lateral drift control technique. |
