CONSTRUCTION TECHNIQUE OF SUPER LARGE SPAN DOUBLE-LAYER NETWORK FRAME DOME

摘要

A construction technique of super large span double-layer network frame dome includes that computer wind tunnel simulated software is used to compute wind load of grid to replace wind tunnel test of the whole spherical shell, so that the accurate steel consumption can be worked out; according to the steel consumption in each square meter, the sizes and nodes of members are worked out; in construction, by ring-by-ring construction closing and a small standing derrick sling, small splicing units are lifted.
