| Abstract |
This study evaluates the displacement tolerance of sky-bridges based on geometric configurations and support types. The maximum
displacement of a sky-bridge exceeds that of the tower due to torsional displacement, making it essential to assess tolerance from the
sky-bridge's end rather than from the tower. The design concept of a linear element with hinge-roller support (pp-rr) is inadequate as it
generates internal stress to satisfy compatibility conditions. Therefore, roller supports should be designed to accommodate multi-directional
displacements (pp-RR). Alternatively, methods to convert transverse displacement demands into longitudinal tolerance (pr-rr) can utilize the
diaphragm rotation of the sky-bridge. Load combinations should consider changes in the principal axis because displacement tolerance should
be evaluated based on the relative displacement between the sky-bridge connected to one tower and the other tower, which can vary with the
principal axis. |
