Weld-Free and Worry-Free: Redefining Structural Efficiency in High-Seismic Regions

图片
 For contractors weary of labor-intensive, time-consuming structural installations—especially in high-seismic zones— bolted steel framing offers a solution that radically redefines safety standards. Its core advantage? A design that guarantees ease of assembly without sacrificing seismic performance, streamlining on-site workflows while meeting every compliance requirement. The days of project delays caused by on-site welding, tedious alignments, or bulky reinforcement are over. Bolted steel components are prefabricated, precision-cut, and pre-drilled, ready for assembly straight off the truck. The intuitive bolting system requires no specialized skills for installation, allowing crews to erect frames with rapid precision, significantly cutting down installation time compared to rigid structures like concrete. No more worrying about mismatched parts or labor-heavy phases—this system is built for high-speed execution, even under the toughest site conditions. But simplicity doesn’t ...

What to pay attention to in the design of a steel truss?

  (1) Cross-section design of rods: The cross-section form of truss rods should be selected according to the conditions of saving steel, convenient connection and simple manufacture, and attention should be paid to make the length and slenderness ratio of rods in two main axes direction (the ratio between calculated length of rods and radius of rotation of the cross-section) as similar as possible, and should meet the requirements of strength, stability and length and slenderness ratio. (2) Strength and stability check: in the calculation of the strength and stability of the bar, the internal force is considered according to the axial force, when the bar is subject to axial force and bending moment at the same time, it should be considered according to the eccentricity of the force and its common role. When calculating the stability and slenderness ratio of the bars, the in-plane and out-of-plane directions of the truss or the unfavorable direction of the larger slenderness ratio ...
