Abstract:
Implementation of skybridges between towers is becoming trendy these days in the
urbanizing world to achieve smart mobility in addition to the aesthetic, spatial and technical
concerns. Emerging new technologies and thoughts of architects made the bridge to build at the
higher elevation which challenging the structural engineers. Predicting the dynamic behaviour of
the skybridge under wind, earthquake and other lateral loadings are vital. Selection of structural
system for the bridge, connection configuration, any damping solution if required are
comprehensively discussed in this paper through a case study. The detailed methodology for design
and detailing of a skybridge that connecting fifty storied twin towers is well formulated in this paper
considering all the aspects that studied through the literature survey. A finite element model is
utilized to perform the analysis for the linked tall buildings under lateral loadings most importantly
under wind loadings. The roller connection is achieved by the customized guided slide bearings.
Further, the viscous dampers are proposed as a supplementary solution to mitigate the excessive
relative movements thus the human comfort is preserved. The authors have also addressed the
aerodynamic stability of the skybridge in this study.
