Advantages of square tube:
(1) Good section performance: Compared with wide-flange H-shaped steel and round steel pipes with equal mass and equal section height, the bending stiffness of square tubes in the two main axis directions is 1.3 times that of round steel tubes, and the bending stiffness in the direction of strong axis Similar to H-shaped steel, the bending stiffness in the weak axis direction is 2.7 times, and the rotation radius is 1.6 times. The results show that the bending stiffness of the steel beam is large, its bearing capacity is significantly improved, and it is more suitable for the case of internode load or secondary bending moment; the larger the radius of gyration is, the more favorable it is to protect the bar; it is confirmed that the whole bar The stability of the structure improves the bearing capacity of the pressure bar; moreover, the greater the rigidity, the better the stability of the structure during hoisting and transportation.
(2) Good corrosion resistance: when using a square tube of the same length, only one side of the tube is corroded after the tube end is closed. In this way, not only the workload of painting and maintenance can be reduced by 1/3, but also the corrosion resistance life is longer than that of H-shaped steel. to be twice as long.
(3) Save engineering costs: Rectangular steel pipes are used for secondary cold-bending welding, which can save complicated box-shaped line processing procedures, simplify construction, and not only improve work efficiency but also save costs.
