Disadvantages of steel magic grid structure

Overall stability and construction accuracy. The geometric size deviation of members and joints and the deviation of curved surface have great influence on the internal force, overall stability and construction accuracy of grid structure, which brings difficulties to structural design. In addition, in order to reduce the initial defects, the processing of bars and joints should require high precision, which increases the difficulty of manufacturing. These shortcomings are more prominent in long-span reticulated shells.
