Considering the requirements of stiffness and strength of structure the final hosting sequence is assured which is ring constraint truss→radial truss-→single-layer reticulated shell-→stiffened truss-→decorative truss.In order to release the welding stress successfully the door-shape plate connection technique for closure is applied and rotation location construction is adopted for ribbon structure in the top of main structure besides support system with the bination of column and beam is used to save cost. Key words:steel roof;reticulated shel...
