High Stiffness X Bracing Frame Symmetric Structural System Seismic Resilience

Product Description
An X-Bracing Frame is a high-stiffness and symmetric structural system characterized by its cross-shaped (X-type) bracing configuration, engineered to provide exceptional lateral stability, load-bearing capacity, and seismic resilience. Manufactured with Q355B/Q460 high-strength steel (bracing members) and Q355B connection plates, this product features two diagonal bracing members intersecting at the midpoint of the frame panel, forming a stable triangular truss structure that efficiently resists horizontal loads (wind, seismic forces) and prevents structural buckling. The bracing members adopt H-beam, box-section, or circular pipe cross-sections (customizable from 150×150mm to 500×500mm) with yield strength ≥345MPa, ensuring lateral stiffness ≥2.0×10⁵ kN/m and anti-seismic performance for zones 6-9 degrees, while limiting structural lateral displacement to ≤H/700 (H=frame height). Connection nodes utilize 10.9/12.9-grade high-strength bolted joints with anti-loosening locking nuts and reinforced stiffeners, ensuring uniform force transmission and resistance to cyclic loads (10⁶ load cycles without performance degradation). Factory prefabrication rate ≥95% guarantees component precision (dimension error ≤±0.5mm) and reduces on-site construction time by 50% compared to traditional bracing systems, while the surface is treated with hot-dip galvanizing (zinc layer thickness ≥85μm), epoxy paint, or fluorocarbon coating, providing salt spray resistance ≥1200 hours and adapting to indoor, outdoor, coastal, and industrial environments. Key features include symmetric force distribution (eliminating unbalanced moments on columns), dual-load-path design (each diagonal member shares lateral loads, enhancing redundancy), and compatibility with large-span (10-50m) and high-rise structures. It complies with GB 50017-2017, AISC 341, and EN 1993 structural standards, supporting customization of bracing angle (45°-60°, optimized for shear resistance), cross-section size, and load-bearing capacity (up to 4kN/m²). Professional services include finite element analysis (FEA) for bracing optimization, BIM-based design integration, on-site installation supervision, and load-bearing capacity testing, ensuring the frame balances structural efficiency, safety, and adaptability.

Applications

X-Bracing Frames are versatile and high-performance structural solutions widely used in commercial, industrial, public, and high-rise buildings, trusted for their superior lateral stability and seismic resilience. Certified by GB 50017-2017, AISC 341, and ISO 9001, they meet strict structural safety standards, making them a preferred choice for engineers and contractors. These frames are widely used in high-rise office towers, residential skyscrapers, and mixed-use complexes (providing critical lateral support for tall structures), large-span industrial workshops, warehouses, and logistics centers (span 20-50m), public buildings (stadiums, exhibition halls, airport terminals) with open-plan designs, bridge structures (beam lateral bracing, pier reinforcement), and seismic retrofitting of existing buildings (enhancing lateral stiffness and seismic performance). They are particularly essential for projects in high-seismic zones (intensity 7-9 degrees) and high-wind areas, where the cross-bracing configuration provides dual load paths and exceptional shear resistance. The system’s compact design also makes it ideal for buildings with limited space for bracing, as it maximizes usable floor area while maintaining structural integrity. The minimum order quantity is 1 set (customized per project), with full tailoring based on architectural drawings, load conditions, seismic intensity, and environmental requirements. Competitive project-based pricing and flexible delivery terms (18-40 workdays based on complexity) support construction schedules for both small and large-scale projects, while a monthly supply capacity of 90 project sets ensures timely delivery. Customization options include corrosion-resistant material upgrades (304/316L stainless steel, super duplex stainless steel) for coastal or industrial environments, fire-resistant coating integration (fire resistance ≥2 hours) for public buildings, and ultra-high-strength Q690 steel for super-tall structures (height ≥200m) to reduce member size and weight. Whether it's for new construction with high stability requirements or existing structure reinforcement, the X-Bracing Frame delivers efficient, safe, and resilient structural performance.
