How to layout support column in steel structure warehouse

How to layout support column in steel structure warehouse?

1. steel structure, building layout, column support:

1) should meet the requirements of steel structure building production clearance;

2) the longitudinal stiffness of the steel structure should be satisfied, and the influence of the arrangement of the column support on the temperature deformation of the structural steel structure and the additional stress resulting from it should also be taken into account.

3) the column brace setting should be coordinated with the steel structure building roof and roof support arrangement, generally the upper and lower horizontal support and the vertical support in the same column in the;

4) each column of each temperature section shall be provided with column support.

The 2. section position of the support column, decided the steel structure building vertical structure of temperature deformation and additional temperature stress, therefore should be as far as possible in the middle temperature section, it can reduce the temperature deformation problem. When the length of the temperature section is not large, a lower section of the middle section of the temperature section is provided with the support between the columns, when the temperature range is greater than 120m. The two section can be set in the support column Du temperature section, its position should be arranged in the middle section of the temperature range of 1/3, the two support center distance should not be greater than 60m, in order to reduce the resulting temperature stress,

3. upper column support, except under section stud spacing between support arrangement, in order to transfer the wind and seismic end gable and improve the vertical steel structure building superstructure stiffness should be set in the support section of stud temperature section ends. The upper and lower columns of both ends of the temperature section have little influence on the temperature stress and can be neglected.

The 4. stepped columns under section stud support in general in two columns are arranged in pairs, namely double support, when the cross-section and the cross-section height is equal to or less than 600mm. Can be arranged along the center line of the columns and monolithic support as large section, should set the double support.

The position of 5. order column column column brace in lateral column, when the column section height less than 1000mm, a monolithic support, and along the column center set, when the bracket supporting truss. The supporting position should be matched with the bracket position. Such as a manhole and a column section of monolithic support, should be considered and will support the channel open manhole side. When the section height of the upper section column is greater than 1000mm, or the upper section is provided with a manhole, and when the longitudinal rigidity requirement is higher, the double plate support can be provided. At this time, the supporting member should be built inside the inside of the two wings so as not to affect the clearance between the column and the crane bridge.
