Abstract：
The external curtain wall supporting system of a specially-shaped rotary twisted super-high structure rotates and contracts while rising, and it is a fully-suspended flexible dynamic special structure. An integral top-down construction scheme, which uses integral suspension lifting platform for construction and operation and sets curved rail traveling tower crane on the truss layer for installation, is adopted to successfully solve the difficulties in the whole construction of curtain wall supporting system. It also provides valuable references for future construction of similar projects.
