A Super-high Twin Towers Conjoined Structure Analysis And Design Of Rigid Connection

Super-tall conjoined modelling and effect is an important expression of architects, but the structure is complex, especially the connection body and connecting body and the main body of the connection parts of the design is an important link in the whole structure design. Conjoined structure and conjoined with the principal part of connection, the influence on the structure and seismic performance of the main building. Of a super-high twin towers conjoined structure with rigid connection, both meet the requirements of the conjoined span larger, has strengthened the stiffness of the main towers, improve the overall aseismatic capability.This paper introduces the simplified model and conjoined structure model in the connection mode of comparative analysis, including structure index, connect body deformation of the truss and the main structure of the influence, according to the results of analysis to determine the connecting truss using rigid connection connected to the main body. For connecting truss under various conditions were analyzed, such as connecting truss under many encounter earthquake stress meet the strength requirements, the construction load is less than a one-time load simulation results for the construction sequence of the internal forces, the bearing capacity calculation of encounter earthquake more to meet the requirements of the elastic target, connecting truss of midspan deflection deformation within the normal range, connecting trusses cantilever of acceleration calculation to meet the requirements of comfort, connecting truss floor temperature stress analysis to satisfy the requirement of the floor slab crack, connecting truss floor in more severe earthquake under the action of the stress calculation of meet the requirements of flexible goals, especially the key node connecting truss, and analysis of the main connection node under severe earthquake is meet performance goals, not to give in to find out in a variety of working conditions is connecting law of seismic response of the truss. A super-high conjoined structure in this paper, based on the actual project as the background, on the premise of using different software analysis, the following conclusions: super-tall structures is higher, the main building height to width is larger, appropriate USES rigid connection, although only a certain effect on stiffness of the main building, but good for connecting the stress of the truss, can effectively improve the span larger conjoined the stress of truss structure.
