How to design steel structure of the two types of anti - vibration column

The cross section of the steel structure plant can not be selected as the cross section of the steel structure, and the section is rotated by 90 ° when the column is arranged. After the hinge is set, the member is hinged at both ends and then the type The
In the software, the anti-pillar is divided into two types, the first one is only bear the wind load, do not bear the roof vertical load; the second type is to bear the wind load, while bear the roof vertical load (both as the swing column) Of the anti-wind column, the frame in the plane (the anti-column outside the plane) need to enter the length of the calculation is still calculated length, rather than calculate the length of the frame outside the plane (anti-vibration column in the plane) need to calculate the length of the input column.
Steel plant
If the windshield of the weak axis direction (within the frame plane) to consider the "wall beam + corner" or the wall frame cross support as a support, then need to manually modify the wind cylinder to calculate the length coefficient, such as: 9000 corner spacing 3000, the input length coefficient of 0.33.
What should you pay attention to when using the section optimization program:
Check the specification of the door frame or Shanghai standard;
Define the section of the component, only concerned with the section type (variable section or equal section), do not care about the cross-sectional size;
Steel plant
The same standard cross section is arranged, and the optimized cross section is the same.
The length of the calculation outside the plane to be modified;
The optimization limits should be selected according to the optimal principles and the actual situation;
Directly derive optimization results for structural calculations.
