![]() Only under pressure: not only the pressure divided by the cross-sectional area of the square steel tubing is smaller than the allowable compressive stress of the square steel pipe, but also whether it will lose stability under pressure.Ĥ. The shearing force divided by the cross-sectional area of the square steel pipe is less than the allowable shear stress of the square steel pipe.ģ. Shearing force only: This is also simple. ![]() Only tensile force: This is the simplest, the tensile force divided by the cross-sectional area of the square steel tubing is less than the allowable tensile stress of the square steel tube.Ģ. The bearing capacity of square steel tubing is divided into the following situations:ġ. There is often a certain relationship between various strengths, and tensile strength is generally used as the most basic strength indicator in use. ![]() Since the load acts in the form of tension, compression, bending, shearing, etc., the strength is also divided into tensile strength, compressive strength, bending strength, and shear strength. ![]() Strength refers to the performance of metal materials to resist damage (excessive plastic deformation or fracture) under static load. For any steel pipe, there is a bearing capacity, and the house pipe is no exception. ![]()
