Square steel post load capacity. Steel square tube is widely used in industrial maintenance agricultural implements transportation equipment truck beds trailers frames etc. Lumber design values are adjusted by the incising factor ci. P is the load in pounds applied at the middle of the tube steel and l in feet i e. The tube steel capacity is calculated by using the formula s m fy where m is expressed point load format m pl 4.

If l is 4 feet long then the load p is applied 2 feet from the support point 3 ft from support for 6 ft long and so on. Wall height is nominal height plus 1 1 8. This is conserva tive for load durations less than normal load duration. The steel weights are tweaked for mechanical tubing and will be less accurate for structural tubing.

Design properties ci moe e 0 95 fc. The beam is laterally supported for its entire length. Post heights are based on standard precut stud heights and associated top plate heights. Note that the maximum factored uniform load capacity for a.

Tables 1 and 3 contain the axial compression design loads for incised lumber. The deflection calculator at this site suggests that such tubing supported at the very ends would experience a deflection of almost a half an inch with. The moduli of elasticity used are 29 700 000 psi for steel and 10 000 000 psi for aluminum.

Shaded values are limited by the perpendicular to grain bearing load p c when posts bear on wood sill. Enter the fy 50 ksi load tables for the 8 in. Effective post lengths l e are the actual wall height minus the thickness of 3 2x plates 4 1 2. The tubing that you suggested 1800mm x 25mm x 25mm with wall thickness of 3mm can be converted to an approximate dimension of 72 long 1 x1 square outside size and a wall thickness of 0 118.

A load duration factor cd of 1 0 is used in determining design loads in this tech note. The section property and load values provided herein are based on nominal material thickness and square corners. Factored uniform load of 52 kips includes the estimated weight of the hss beam. The calculated section property values do not comply with the aisi or aisc specifications since minimum material thickness and rounded corners were not used.
