Aircraft hangars are special large-span steel structure buildings . The main design challenges are the ultra-large column-free clearance, structural stability, and resistance to wind and snow. There are three main types of hangar structures on the market: portal frame, bolted ball structure, and tubular truss. These three types differ significantly in their load-bearing principles, span capacity, cost, and applicable scenarios, which are also the main basis for hangar scheme selection, budget control, and construction implementation (design should follow local standards, such as EU Eurocode, US IBC, etc., specific local standards prevail). 1. Portal Frame Structure Structural Principle: A portal frame is a rigidly connected steel column and beam structure forming an integral portal frame, belonging to a planar load-bearing structure. The load is directly transferred to the steel columns and foundation through the roof steel beams. The system is simple, the force transmission is clear, ...

  Steel structure workshops have the characteristics of high strength, large span, high flexibility and fast construction. They can meet the needs of the manufacturing industry and provide enterprises with a good production environment. Therefore, they are widely used in the manufacturing industry. In the manufacturing industry, some workshops usually need to bear the load of heavy equipment and complex processes. Steel structure workshops use steel as the main building material. Steel has high strength and stability. This strength and stability enables industrial workshops to withstand the storage and transportation of heavy equipment, a large number of items, and possible natural disasters such as earthquakes, thereby ensuring the safety of personnel and the continuity of production. At the same time, the manufacturing industry has high requirements for the flexibility and scalability of workshops. The high strength of steel allows steel structure workshops to be designed as lar...

The span of a coal storage silo isn't determined arbitrarily. In actual engineering, it's mainly constrained by five factors: storage capacity, site dimensions, on-site equipment, wind and snow load, and investment budget. Below, we'll break down these five factors to help you determine which span your project should lean towards. 1. Storage Capacity Requirements: The size of the storage directly determines the required storage area. With a fixed site length, the larger the storage volume, the more you need to increase the span to gain area. For projects with tens of thousands of tons of storage, a small to medium span of 30-60 meters is usually sufficient; for projects with hundreds of thousands of tons, such as ports and energy bases, a column-free span of hundreds of meters is often required. Simply put: if the storage volume is too small, the span cannot be too large. 2. Site Dimensions: Even with an ideal span, it still needs to fit. The site boundary, shape, and exist...

During the design phase of coal storage bunkers , many owners generally believe that the larger the span, the higher the site utilization rate and the better the project effect, thus blindly pursuing ultra-large span designs.  However, in actual engineering applications, a larger span for coal storage bunkers is not always better. While ultra-large spans bring spatial advantages, they also lead to increased costs and design complexity. A reasonable span selection requires a comprehensive assessment based on the project's coal storage scale, site conditions, equipment configuration, and investment budget to ensure suitability for the project, safety compliance, and optimal economic efficiency. 1. Core Advantages of Large-Span Coal Storage Bunkers A reasonable large-span design can significantly improve the performance and operational efficiency of coal storage bunkers. Large-span structures allow for an open, column-free layout, resulting in a more spacious and regular overall stora...

 Many owners focus on the structural service life of enclosed coal storage sheds when constructing them, assessing the project's cost-effectiveness and long-term operational stability. The service life of a steel structure coal storage shed is not a fixed value; it is primarily determined by design standards, construction techniques, anti-corrosion systems, the operating environment, and subsequent maintenance. Under standard operating conditions of standardized design, qualified construction, and normal operation and maintenance, the overall service life of a steel structure coal storage shed can generally reach over 30 years. This article details the service life standards for coal storage sheds, key influencing factors, and practical methods to extend structural life. 1. Conventional Service Life of Steel Structure Coal Storage Sheds Provided that national building design codes are met, standard anti-corrosion processes are adopted, construction quality meets standards, and dai...

 I. What is a Coal Storage Shed? A coal storage shed is a large-span, enclosed industrial building suitable for storing coal and various bulk materials. Its core function is to fully cover and shield the stored materials, isolating them from the effects of rain, strong winds, sun, frost, and other natural weather conditions. It also effectively curbs the spread of coal dust, significantly reducing coal material loss and regional environmental pollution. It is a core supporting facility for industrial bulk material storage. With the continuous tightening of national environmental protection policies and the ongoing upgrading of industrial green production standards, traditional open-air coal yards are gradually being replaced by standardized enclosed coal storage sheds due to their shortcomings such as high pollution, high losses, and difficulty in management. Currently, coal storage sheds are routinely used in bulk material storage yards of various industrial enterprises, including...
