“…A graphical A Study on Static and Dynamic Behavior of Outrigger Structural System for Tall Buildings Kiran Kamath, N. Divya, Asha U Rao T method of analysis is presented for preliminary design of outrigger truss-braced high-rise shear wall structures with nonfixed foundation conditions subject to horizontal loading. [10], documented the restraining moments of outriggers acting on the core wall and the equation of the horizontal top deflection based on a simplified outrigger model. The deformation compatibility conditions between outriggers and core wall as well as the finite rigidities of outriggers are also [12], carried out the analysis to find the optimum location for the second outrigger by changing the position of second outrigger along the height of the building and placing it in all the possible locations, i.e.…”

Due to creep and shrinkage of concrete, the long-term structural deformation is one of the hottest topics in the study of super high-rise structures. For the frameeccentrical core tube structure, its long-term deformation includes both vertical deformation and obvious horizontal deformation, which will have an inevitable influence on the structural verticality. The horizontal deformation and its formation mechanism in frame-eccentrical core tube structure are studied in this paper. Based on the finite element software ETABS, a refined finite element model combining with the time-dependent material model of concrete is established base on a subsistent structure. According to the actual construction conditions, construction analysis is conducted, and the construction deformation and the long-term deformation after completion are subsequently studied. Based on the results of construction analysis, the effects of elastic modulus, creep, and shrinkage on structural horizontal deformation are analyzed; furthermore, the horizontal deformation characteristics of different structural members in different periods are compared. The results show that the horizontal deformation is related to the vertical deformation of the component, and creep and shrinkage exert opposite effects on the structural horizontal deformation. Besides, the creep and shrinkage are the dominant factors of the horizontal deformation in the later stage. These results are supported by real deformation data obtained from real-time deformation monitoring during construction, which proves the effectiveness of the method adopted in this paper.
