K Value For Cantilever Column

Since actual column conditions seldom comply fully with idealized conditions used in.

K value for cantilever column. For columns which are prone to buckling as per clause 9 3 3 k will be determined by either appendix b and c. In my case it is partially acting as a cantilever only because the roof diaphragm has forced it to move. Cantilever column systems are permitted as indicated in table 12 2 1 and as follows. Cantilever racking is the optimal storage solution for long or bulky items such as furniture lumber tubing textiles.

The column module typically assumes a pin pin connection for the end supports but the end condition can be changed to a cantilever inside the module. For the same cross sectional area a section with higher moment of inertia produces a more stable column with. It carries a load along the free arm or at the free end. The column module typically assumes a pin pin connection for the end supports but the end condition can be changed to a cantilever inside the module.

The recommended k factors are also shown in figure 17 2 for practical design ap plications. Asce 7 10 table 12 2 1 item g sets forth very low design coefficients and factors with strict height limits for cantilever column systems. Figure 17 2 1 3 4 summarizes the theoretical k factors for columns with some idealized end conditions. The k factor approximates the length that a column steel column s concrete column s aluminum column s etc.

A slanting beam is fixed frequently from the arm to the column to provide additional support. Once a cantilever has been designated by selecting the cantilever column checkbox the column end condition or k e value will change from 1 to 2 1 and the top of the column will then be unrestrained. K values for columns a b c d e f buckled shape of column is shown by dashed line theoretical k value recommended design value when ideal conditions are approximated. In another word s16 94 removed the k value chart for columns of side sway permitted.

Once a cantilever has been designated by selecting the cantilever column checkbox the column end condition or k e value will change from 1 to 2 1 and the top of the column will then be unrestrained. Slender columns 4 4 may be used to establish conservative values of k for braced columns2. Since that movement is relatively small i m gathering from everybody s response that a k value of 1 0 is adequate. All use the effective length factor actually buckles the effective length can be longer shorter or exactly the actual length depending on the rigidity of the supports.

Effective length k factor explained. Asce 7 10 section 12 2 5 2 addresses them as follows. End condition code 0 5 0 7 1 0 1 0 2 0 2 0 0 65 0 80 1 2 1 0 2 10 2 0 rotation fixed and translation fixed rotation free and translation fixed rotation fixed and. Appendix c is for k value of columns in a continuous frame with side sway prevented.

Appendix b gives the column k values ranging from 0 65 to 2 0. The beam is supported rigidly at one end by connecting it to the column.
