Industrial Mechanical

In steel structure projects, especially steel warehouse buildings and industrial workshops, high wind load is often the controlling design factor. With more than ten years of experience as a steel structure manufacturer, we regularly face a practical decision in overseas projects: choosing between a portal frame structure and a truss structure for high wind conditions. 1. Structural Behavior Difference A portal frame steel structure works through rigid beam-column connections. Wind load is mainly resisted by bending moments at the column bases and knee joints. The system behaves like a stiff frame, simple and efficient for standard industrial buildings. A steel truss structure, on the other hand, uses triangular geometry. Wind force is broken down into axial tension and compression in...
