grid structures  are a type of highly statically indeterminate spatial truss structure. Due to their excellent load-bearing performance (in theory, truss members are only subjected to axial forces), high stiffness, excellent overall integrity and seismic performance, strong load-bearing capacity, minimal influence from uneven settlement of supports, and high adaptability. With the continuous improvement of computational theories and the rapid development of computer technology, analysis and design of any extremely complex three-dimensional structures have become feasible. Therefore, grid structures  are widely applied in industrial and civil building fields. However, if the supporting structure, bearing type, and boundary conditions of a space truss structure are designed improperly, it can significantly impact the safety and economy of the structure. The bearing nodes of a space truss structure must ensure safe and reliable transmission of bearing reactions, and therefore mus...

  1. Why is a s teel   structure needed for long-span coal sheds ? In modern power plants, port coal terminals, and mining coal storage yards, large-span enclosed coal sheds have become the industry standard. Key reasons include: (1) Increased environmental protection requirements :  Enclosed storage reduces dust emissions. (2) Concentrated site space : Large coal sheds often require column-free, large-span spaces of 80 – 150 meters or more. (3) Large coal storage capacity and high load :   Coal pile height can reach 15 – 30 meters, placing higher demands on the lateral stability of the structure. In this context, steel   structures have gradually become the preferred system for power plant coal sheds, especially with significant advantages in wind-resistant design, lightweighting, and rapid construction. 2. Core Challenges in Common Coal Shed Construction Based on years of project experience, LF has identified key client concerns. Do you face any of these issue...

 When stadium construction costs exceed the budget, it is rarely due to waste during construction; rather, the issues usually stem from unreasonable initial design choices, over-design, or improper parameter planning. Stadiums are public buildings characterized by large spans, vast open spaces, and extensive supporting facilities. Among these components, the roof system accounts for the largest share of costs and exhibits the greatest cost variance, directly determining the project's overall investment. With years of deep expertise in steel roof structures for stadiums, LFBJMB maintains that the key to cost control lies in optimizing designs at the source—eliminating redundancies without compromising safety or functionality—to deliver a project with high cost-effectiveness. I. Core Cost Components of Stadiums The overall cost of a stadium comprises nine major segments. The roof system accounts for 30%–50% of the total, making it the top priority for cost control and the primary fo...

 Sports venues are large-scale public buildings involving multiple disciplines, including architecture, structural engineering, MEP (mechanical, electrical, and plumbing) systems, and fire safety. It is not necessary to have a complete set of construction drawings during the initial project phase; instead, data can be prepared according to the specific stage. The completeness of this data directly determines the accuracy of the design, cost estimation, and construction planning, effectively reducing the need for subsequent changes and minimizing communication costs. I. Essential Basic Data for the Initial Project Phase (Applicable to All Stages) This constitutes the core information required for design and cost estimation: 1. Project Location: Specify the country, city, and specific site. This determines applicable design codes, wind and snow loads, seismic parameters, temperature and humidity conditions, environmental corrosivity, and logistics/transportation constraints; it is th...

  Steel structures are primarily composed of steel components, characterized by steel beams, steel plates, steel columns, steel trusses, and other elements; they are a major type of building structure, connected through welding, bolts, or rivets between each member or component. When damage occurs in a steel structure, it should be identified and addressed immediately. (1) Insufficient load-bearing capacity due to changes in load, overtime work, or revisions to standards and regulations; (2) Deformation, distortion, loss of functionality, or indentation of components caused by various accidents, leading to weakened cross-sections, warped members, or cracked connections; (3) Deformation, cracking, or warping of components or connections caused by temperature differences; (4) Corrosion and electrochemical corrosion caused by chemical erosion, weakening the cross-section of steel structure components; (5) Other issues including errors in design, production, or construction, as well a...

Double-layer laminated glass—also known simply as laminated glass—is a composite product formed by sandwiching one or more layers of organic polymer interlayers between two or more sheets of glass. Through specialized high-temperature pre-pressing and high-temperature, high-pressure processing, the glass and interlayers are bonded into a single, integrated unit. Common interlayer materials include PVB (polyvinyl butyral), SGP (ionoplast interlayer), EVA (ethylene-vinyl acetate copolymer), and PU (polyurethane). These interlayers are characterized by transparency, elasticity, strong adhesion, and excellent penetration resistance. Even if the glass breaks, the fragments adhere to the interlayer, keeping the broken surface neat and smooth; this effectively prevents injuries from sharp shards and accidents involving falling glass. Production Methods: 1) Film Heat-Pressing Method (Dry Method): Glass sheets and interlayers are stacked in sequence and placed in an autoclave. They undergo heat...

Partial Issues and Solutions in Steel Structure Construction 1. Component Manufacturing Issues The plates used in portal frames are very thin, sometimes as thin as 4 millimeters. For cutting multiple thin plates, shearing should be selected over flame cutting. Flame cutting causes significant wave-like deformation along the plate edges. Currently, most manufacturers use submerged arc automatic welding or semi-automatic welding for H-beam welding. If not properly controlled, welding deformation may occur, causing components to bend or twist. 2. Column Base Installation Issues (1) Embedded Parts (Anchor Bolts) Problems: Overall or layout misalignment; incorrect elevation; lack of thread protection. Directly causes misalignment of steel column base plate bolt holes, resulting in insufficient thread length. Measures: Structural steel contractors must coordinate with civil engineering teams to complete embedded part installation before concrete pouring. Relevant dimensions must be verified,...

  As an efficient building structure, steel frames have gained widespread application in modern architecture. Their lightweight, aesthetic appeal, and high spatial utilization make them the preferred structural form for many large-span buildings. However, designing space frame structures is not straightforward; it requires comprehensive consideration of multiple factors to ensure structural safety, economy, and functionality. This article will explore in detail the primary conditions that should be considered in space frame design. 1. Load Conditions Designing space structures must be grounded in load analysis. Load conditions form the core basis for design, encompassing dead loads, live loads, and special loads such as wind loads and seismic loads. Designers must accurately calculate the magnitude and distribution of various loads based on the building's functional requirements and geographical location. For instance, in large-span structures like stadiums or exhibition halls, li...
