Key control point of Long Span space frame construction bulk storage sheds – High Stress Level

The long-span space frame structure bulk storage is different from the common steel structure. It has a series of characteristics such as: large span, light weight, large roof area, running in bad environment, etc. There are some design particularities, among which the following major aspects require special attention when building.

For some large-span and super large-span space frame structures, the construction company usually controls the project cost strictly. In order to reduce the quantity of steel used, the designer adopts the full-stress design method in the design process, which causes the whole stress level of structural members to be much higher.

If in the design stage for some additional load such as node weight, member self- weight and so on, the estimation is not enough to ensure an reasonable safety reserve, but in the construction process, some equipment load is temporarily increased, which will cause pipe overstressed.  This is the main problem that affects the safety of the whole structure, and it is also the important reason that causes the collapse of many bolt connection space frame structure bulk storage sheds.
