Steel Codes & Seismic Design for Space Frames

图片
Introduction In seismically active areas, steel space frames must not only meet load-bearing requirements but also exhibit excellent seismic performance. This article will discuss the seismic design codes, key design points, and their application in practical projects. Seismic Design Codes for Steel Space Frames China's "Code for Seismic Design of Buildings" (GB50011): Applicable to seismic design in mainland my country, it specifies structural seismic resistance levels, design basic earthquake accelerations, and structural categories. USA's "Code for Seismic Design of Steel Structures" (ANSI/AISC 341): Applicable to the United States, it emphasizes the ductility and energy dissipation capacity of structures and provides specific requirements for seismic design. European "Code for Seismic Design of Steel Structures" (EN 1998-1): Applicable to Europe, it incorporates the characteristics of steel structures and provides guiding principles for seism...

Steel Space Frame Maintenance Challenges & Long-Term Cost Management

图片
 Introduction Steel space frames offer great strength, large spans, lightweight, and architecturally appealing visual appeal. However, maintaining these advantages requires addressing several maintenance challenges and considering long-term cost management. Mastering these challenges can save significant repair costs and extend the life of the structure. Common Maintenance Challenges for Steel Space Structures 1.Corrosion & Rust Steel is susceptible to rust in environments exposed to humidity, sea breezes, or chemical vapors. Inadequate protective measures (galvanizing, powder coating, or corrosion resistant coatings) can reduce the metal's cross-sectional area and lower its load-bearing capacity. 2.Thermal Bridging & Energy Loss Steel is a highly conductive material. Without proper insulation and sealing in the structural design, energy can be lost through the steel components, leading to heat loss in winter and difficulty dissipating heat in summer. 3.Fire Resistance Issu...

Steel Space Frame vs. Truss & Rigid Frame: Which Roof System Is Right for You?

图片
  Introduction When planning large-span buildings, choosing the right structural system is key. Here's how steel space frames , trusses , and rigid frames compare in terms of design flexibility, materials usage, construction speed, and cost. Strengths & Highlights Steel Space Frames – Outstanding load distribution across three dimensions—exceptional stability and seismic resilience. – Fast, modular assembly with factory-made precision (like Lego™) . – Supports stunning architectural forms with minimal internal columns. Space Trusses – Highly efficient at handling long spans using minimal material through axial load strategies. – Flexible in form—works well for pitched or curved designs. Rigid Frames – Reliable for clear spans under ~90 m, using standard moment connections. – Simple to fabricate and quick to erect; great for industrial or retail use. Practical Guidance Choose space frames if your project prioritizes architectural expression, large span, and o...

How Steel Space Frame Roofs Revolutionize Large-Scale Architecture

 LF-BJMB steel frame roofs are reshaping how we conceive large buildings—from stadiums and exhibition halls to airports and shopping malls. Thanks to their light weight, flexibility, and strength, they're enabling grand design without compromising performance. Key Advantages of Steel Space Frame Roofs 1. Exceptional Strength-to-Weight Ratio Steel space frames distribute loads across geometric networks of struts and nodes, enabling light overall weight while maintaining robust structural capacity—even in seismic or heavy-weather regions. 2. Structural Efficiency & Reduced Foundation Load Because these systems use less material and distribute weight evenly, the load on foundations is minimized—simplifying construction and reducing costs. 3. Wide-Clear Spans Without Internal Columns Space frames allow column-free interiors across vast spans, unlocking unobstructed spaces for venues like arenas or exhibition centers. 4. Architectural Freedom Their modular nature supports domes...

Why Steel Space Frame Structures Are Building the Future

A steel space frame , or 3D truss structure, is an engineering marvel: composed of interlocking steel struts arranged in triangular geometry, it enables wide-span, column-free spaces with exceptional strength and lightweight efficiency. Key Advantages of Steel Space Frame Structures 1. Superior Strength with Minimal Weight These structures distribute loads evenly through an interlocking grid, providing high load capacity while using less materials —crucial for resilience in earthquakes, wind, and snow. 2. Lightweight Yet Durable Thanks to efficient geometric design, steel space frames are lightweight. This reduces foundation needs and simplifies logistics.Steel’s corrosion resistance and protective coatings ensure durability and low maintenance over decades. 3. Flexible Design for Open Spaces This system enables bold architectural forms—domes, curved roofs, vaults—with vast, open interiors free of columns. 4. Fast Prefab & Assembly Components are prefabricated off-site and b...

Space Structures for Disposable or Temporary Community Shelters Introduction

图片
 In emergency relief, disaster response, or temporary events, community shelters must be portable, fast to set up, and adaptable to various conditions. Space structures—lightweight, modular frameworks—are ideal for swift deployment, durability, and sustainable reuse. Key Advantages of Space Structure Shelters Fast Assembly & Modular Design Prefabricated struts and nodes can be rapidly assembled by untrained personnel—vital during crises. The modular modules allow scalability and flexible layout setup ([turn0search20]). Lightweight yet Resilient Using materials like aluminum or thin-gauge steel, space frames achieve high strength while being lightweight—minimizing transport and handling efforts. Recyclable & Reusable Unlike disposable tents, many space structure shelters can be recycled or reused across multiple sites—supporting circular, eco-friendly operations. Adaptable Cladding Options Inner layers can use fabrics, panels, or quick-deployed materials dep...

How Steel Canopies Shield Southeast Asian School Arenas

For international schools in Manila, Jakarta, and Ho Chi Minh City, outdoor sports events face twin threats: monsoon downpours halt games while aging concrete bleachers risk collapse. As a global steel structure specialist with 50+ ASEAN projects, we engineer typhoon-defying spectator canopies—where safety meets spectacle. As a global steel structure expert with over 50 projects under our belt, we designed a typhoon-resistant spectator canopy that combines safety with spectacular views. 3 Pain Points You Can’t Ignore Monsoon Disruption Your chaos: Manila’s 200mm/hr rains cancel 40% of annual sports events → parent complaints + revenue loss. Our shield: Slope-optimized roofs drain 4X faster than standard designs + 150μm hot-dip galvanizing protects against salt corrosion. Structural Peril Your fear:   B leacher collapse injures students during monsoon winds. Our safety: Seismic-braced frames withstand 200km/h winds + real-time load sensors. Budget ...
