“…Compared with the numerical results of the research object in the literature, [43] it is reasonable that the connector is located in the middle of the conjoined structure. From the perspective of simplifying the super high-rise building to a cantilever beam, the connection point located in the middle of the structure is more in line with the bending moment distribution.…”

Connected super high-rise structure has a long construction period and significant time-dependent characteristics, so it is necessary to study its vertical deformation during construction. Taking an asymmetrical three-tower conjoined super high-rise structure as engineering background, the equivalent elasticity problem was analyzed by age-adjusted effective modulus method, and vertical deformation formula was deduced. A simplified model and a refined model of structure were established. The correctness of the deformation formula and modeling had been proven by comparing the dynamic characteristics and numerical simulation results. Based on the simplified model, the optimal construction plan of the conjoined super high-rise structure was discussed. Based on the deformation formula, the predeformation calculation method of the conjoined super high rise was studied, and the correctness was verified by numerical simulation. The results show that the largest vertical deformation of the connected structure occurs at the position of corridor, and an apparent mutation occurs here. Properly delaying the rigid connection timing between corridor and tower is beneficial to the control of the overall structural deformation difference and internal force. The predeformation analysis method proposed in this paper is correct and effective, which could offset the vertical deformation of the structure during the construction sequence.

“…There is also a certain amount of research on ordinary twin-tower connected super high-rise structures. Ma et al [43] analyzed the vertical deformation of a twin-tower connected super high-rise structure. But there is no relevant research on the vertical deformation and predeformation during construction of threetower connected super high-rise structures.…”

In this paper, the influence of the construction process of large-span steel latticed arch on the geometric configuration and bearing capacity performance of the large-span steel latticed arch is calculated and analyzed by using the inverse analysis technique. By comparing the calculation results of single pre-deformation adjustment of the node co-ordinates in zero state of the whole structure and the dynamic adjustment of the node co-ordinates of the unconstructed part of the structure, it is found that the inverse analysis method of dynamic node co-ordinate adjustment is used to achieve the unification of the geometric configuration of the final structure and the bearing capacity performance of the structure. The results show that the inverse analysis method of dynamic node co-ordinate adjustment proposed in this paper can simulate and track the dynamic changes of structural geometry and stable bearing capacity performance in the actual construction process, which can not only consider the influence of the installed part of the structure on the co-ordinate adjustment value of the uninstalled part of the structure but also consider the deformation influence of the subsequent uninstalled structure on the installed structure and can realize the optimal approximation of the final state structure to the geometric configuration of the zero state structure and the accurate calculation of the bearing capacity performance with the progress of the construction process.
