 As Vietnam continues to develop its transport infrastructure, airport terminal design presents an important engineering challenge: how can large public buildings accommodate complex passenger flows, create open and functional spaces, and support efficient construction? Long-span steel structures can help address these challenges by providing flexible, column-reduced spaces for modern airport terminals and other large public buildings. For airport developers, architects, and EPC contractors, several factors deserve particular attention when evaluating structural solutions in Vietnam. 1. Designing for Vietnam’s Tropical Climate Vietnam experiences a tropical monsoon climate, with regional differences in rainfall, wind conditions, temperature, and exposure to coastal environments. For airport terminals, these conditions make climate-responsive structural design essential. Key engineering considerations include: Wind resistance: Structural systems and roof connections should be des...

Unlike standard industrial buildings, aircraft hangars are highly customized long-span aviation structures. There is no fixed construction timeline for hangar projects. The overall delivery cycle depends on design standards, structural solutions, site conditions, and supply chain arrangements. With rich overseas hangar project experience, LFBJMB breaks down the full project phases and core factors affecting construction progress, helping clients accurately schedule construction and avoid delivery delays. 5 Core Construction Phases of Aircraft Hangars 1️⃣ Demand Confirmation & Scheme Planning Clarify applicable aircraft models, parking/maintenance functions, scale, budget and expansion plans. Clear early positioning avoids repeated design revisions and rework. 2️⃣ Multi-disciplinary Professional Design Cover architectural layout, long-span structural calculation, hangar door system, fire protection, MEP and enclosure design. High-precision structural verification determines subs...

The primary technical challenges in stadium construction lie in the long-span roof. Unlike conventional buildings, stadiums require vast column-free spaces, unobstructed sightlines, and the ability to accommodate complex architectural forms, all while ensuring resistance to wind and seismic forces, effective drainage, and long-term durability. Currently, the three most widely used roof systems—both domestically and internationally—are bolted-ball structures, tubular truss structures, and cantilevered steel structures; landmark stadiums may also employ specialized systems such as string-supported structures or cable-membrane structures. 1. Bolted-ball structures The bolted-ball structure is a mature and commonly used roof system for indoor stadiums. It consists of steel tubes connected at bolted-ball nodes to form a three-dimensional grid—resembling a 3D honeycomb—resulting in excellent structural integrity. Key features: Three-dimensional load distribution ensures even load dispersion...

 Many people conflate the design of indoor arena roofs with that of football stadium roofs; however, based on LFBJMB’s extensive experience delivering overseas stadium projects, the design logic for each differs fundamentally. Indoor arenas prioritize enclosure, airtightness, and full coverage, whereas professional football stadiums are open-air venues where the primary requirement is to shelter the stands while leaving the pitch exposed. Almost all modern professional football stadiums utilize long-span cantilevered roofs. This structural form—which avoids obstructing views or blocking natural light to the pitch while simultaneously providing shade, rain protection, wind resistance, drainage, and equipment mounting capabilities—is the optimal choice for football venues. This article outlines the core design principles and key pitfalls to avoid regarding football stadium roofs (please note that overseas projects must strictly adhere to local national codes; this article serves only...

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...
