Modern steel structure platform structure has various forms and various functions.Fully assembled structure, flexible design, can design and manufacture a steel structure platform that meets the site requirements, use functional requirements and logistics requirements according to different site conditions.It is widely used in modern storage.
Generally speaking, the carrying capacity of the structural platform is also relatively large, so what are the standards of the steel structure platform in the design?How to design more economical materials?What are the environmental factors and other uncertainties to consider in the design of the steel structure platform?Let's take a look together.

1. Column distance selection
When the more economic column under the standard load is 8~9m, more than 9m, the steel amount of the roof column bar and wall frame system will need to increase a lot, and the comprehensive cost is not economical.Here the standard load refers to: the roof live load 0.3KN/m2, basic air pressure 0.5KN/m2, when the load is larger, the economic column distance should be reduced accordingly.For plants with over 10 tonnes, the economic column should be 6~7m.

When arranging the column distance, if the unequal column distance needs to be used, the end span distance should be smaller, because the wind load is larger than the middle span, in addition, the end span and the middle span are always larger than the other span.The smaller end span can make the roof bar design more convenient and save.

For example, 1, the length of a building is =70m
Economic column distance is desirable: 1@7 + 7@8 + 1@7 or 1@8 + 6@9 + 1@8
2: Building length =130m, driving 10 tons
Economic column distance is desirable: 1@5.5+17@7+1@5.5 or 20@6.5
