CONSTRUCTION PROCESS OF ARCH SHED STORAGE SILO WITH SUPER-LARGE-SPAN FRAME

摘要

A construction process for an arch-shed storage silo with a super-large-span frame comprises: first, according to local meteorological conditions and on the basis of worst-case meteorological conditions and arch-shed physical parameters, obtaining, by means of a CFD numerical wind tunnel calculation technology and a finite element algorithm, dimensions for each frame node rod piece, namely a ball diameter for each node and the geometric parameters of rod pieces mounted thereon, and drawing a construction drawing comprising at least the serial number of each node and the number of rod pieces at each node; then dividing the construction steps among basic-unit installation and cantilever-unit installation. As there is no need for full-site scaffolding, the construction process is time-saving, material-saving, safe and reliable.
