Product Description
A Seismic-Resistant Primary Steel Frame is a high-resilience structural system engineered to resist seismic forces (intensity zones 7-9 degrees), integrating energy dissipation, ductile design, and moment-resisting capacity. Manufactured with Q460/Q690 ultra-high-strength steel (beams, columns) and Q355B connection plates, this product features a dual-functional design: rigid bolt-welded joints (moment-resisting capacity ≥800kN·m) to maintain structural integrity, and integrated buckling-restrained braces (BRBs) or viscous dampers to absorb 30%+ of seismic input energy. The main beams and columns adopt box-section or H-beam profiles (beams: 400×200mm-900×400mm; columns: 300×300mm-700×400mm) with yield strength ≥460MPa, optimized for ductility (plastic hinge formation in designated areas) to avoid brittle failure. Key features include lateral stiffness ≥1.8×10⁵ kN/m, inter-story drift ≤1/500, and compliance with GB 50011, AISC 341, and EN 1998 standards. The surface is treated with cathodic electrophoresis + fluorocarbon coating (dry film ≥120μm), providing salt spray resistance ≥1500 hours. Factory prefabrication rate ≥95% minimizes on-site welding (a seismic vulnerability), with dimension error ≤±0.5mm. Professional services include pushover analysis, seismic performance simulation, on-site installation supervision, and post-earthquake structural assessment.
Applications
Seismic-Resistant Primary Steel Frames are critical for buildings in earthquake-prone regions, protecting lives and property during seismic events. Certified by GB 50011, AISC 341, and ISO 9001, they meet international anti-seismic standards. Typical applications include high-rise residential and office buildings (seismic zones 7-9 degrees), public buildings (hospitals, schools, emergency command centers), industrial facilities (data centers, chemical plants with critical equipment), and infrastructure (subway stations, bridge piers). They are particularly essential for projects requiring post-earthquake functionality (e.g., hospitals) and high-rise structures in active seismic zones. The minimum order quantity is 1 set (customized per project), with full tailoring based on seismic intensity, building height, and load conditions. Competitive project-based pricing and flexible delivery terms (25-50 workdays) support construction in seismic-prone areas, while a monthly supply capacity of 60 project sets ensures timely delivery. Customization options include corrosion-resistant upgrades (316L stainless steel) for coastal seismic zones, fire-resistant coating (≥2.5 hours) for public buildings, and ultra-high-strength Q960 steel for super-tall structures.
