 The design approach for a football stadium roof differs from that of a standard indoor sports arena. As open-air professional venues, football stadiums demand high levels of openness, unobstructed spectator sightlines, and suitability for an outdoor environment; one cannot simply replicate the space-frame or truss systems used for indoor facilities. LFBJMB specializes in long-span steel structures; professional football stadiums typically employ long-span cantilevered roofs. The primary objective is to cover the stands while leaving the pitch open to the sky, all while addressing needs for rain and sun protection, wind resistance, drainage, and the installation of various equipment. Note (Overseas Projects): The span magnitudes and coverage ratios mentioned below represent common industry ranges and serve only as references for preliminary selection. Designs for overseas projects must comply with the regulations of the host country. 1. Key Design Considerations for Football Stadiu...

 When planning a hangar project for the first time, many aviation infrastructure owners tend to equate hangars with standard industrial workshops. In reality, aircraft hangars are specialized, long-span steel structures that integrate multiple professional systems—including the structure itself, hangar doors, fire protection, and electromechanical systems. Each construction phase is interdependent; errors in early decision-making can directly lead to rework, cost overruns, and operational inadequacies later on. Drawing on practical experience with long-span aviation projects, we have categorized the hangar project process into five key stages. By clarifying the core objectives of each stage, we help owners gain a comprehensive understanding of the project; you can also visit our official website for further details. I. Project Requirement Analysis: The Foundation for Project Implementation Clarifying requirements before officially launching the design phase is the most effective wa...

 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...
