The Volgograd Football Stadium in Russia is shaped like an inverted truncated cone. The building’s facade was designed based on the image of a solemn salute. The entire diamond-shaped structure consists of a reinforced concrete shell. From the tops of the lower-level diamond modules, branches with smaller cross-sections extend upward, intersecting at higher elevations to create a magnificent pattern reminiscent of a rocket launch. Thanks to the highly compact organization and development of the site and plot, this project maximizes the efficient use of land resources. The spaces between the steel beams of the building’s facade shell are filled with stainless steel mesh, giving the entire stadium a unique aesthetic appearance while also serving as a windbreak for spectator lounges and lobbies. The design of the stadium takes into account the needs of people with mobility impairments. For example, it features 460 seats designated for people with disabilities, as well as high-sound-press...

 Spatial structures have become a widely adopted structural form in recent years. Composed of bolt-ball nodes and seamless steel tubular members, these highly indeterminate structures are assembled using high-strength bolts or welding connections. They are characterized by a low steel-to-span ratio, excellent seismic resistance, short construction cycles, and aesthetic appeal. These structures are extensively utilized in large-span engineering projects, such as sports stadiums, airport terminals, high-speed railway stations, industrial plants, and large-scale storage warehouses. However, during the actual production, fabrication, and installation processes, two key factors can still significantly impact the overall quality of bolt-ball space frame structures. (1) Insufficient Strength of High-Strength Bolts In bolt-ball space frame structures, the strength of the high-strength bolts (which are capable of bearing significantly higher loads compared to standard bolts of the same si...

 The global energy transition is accelerating, driving sustained growth in demand for new energy power plants such as wind, solar, and hydrogen facilities. In these projects, steel structures are increasingly becoming the core choice for building and support systems due to their high strength, excellent weather resistance, and design flexibility, providing critical support for the implementation of new energy infrastructure. 1. Construction Trends in New Energy Power Plants The construction of new energy power plants is booming, with steel structures indispensable across all plant types. In wind power, both onshore and offshore wind farms are expanding their installed capacity. The towers, nacelle platforms, and maintenance walkways of these wind turbines rely heavily on steel structures to ensure stable operation. For photovoltaic power stations, steel support structures and corrosion-resistant components are particularly crucial. They must continuously bear the weight of solar pa...

 As a common and crucial spatial structural form, bolted sphere trusses play a vital role in various buildings. However, during actual use, multiple factors may lead to their damage, posing potential threats to building safety. Gaining a thorough understanding of these damage factors is essential for ensuring the safe and stable operation of bolted sphere trusses. Load and Structural Load-Bearing Capacity Issues Load variations are a primary cause of damage in bolted sphere trusses. During use, live loads may increase due to changes in building purpose—such as converting warehouses to store heavy equipment—exceeding design capacities. Extended service life leads to accumulated fatigue damage in steel, reducing load-bearing capacity. Updates to standards and codes may also render original designs non-compliant. These factors can trigger structural overload, causing member deformation, joint loosening, and other failures. Accidental Deformation and Damage to Components Damage such as...

  Coal resource storage is a core component of coal mine production, providing buffer support for production systems while enabling precise utilization of coal quality through categorized storage. With advancements in coal storage technology, its role in environmental protection and efficiency enhancement has become increasingly prominent, serving as a vital pillar for enterprise transformation. 1. Evolution of Mainstream Coal Storage Methods After multiple rounds of technological innovation, current mainstream storage methods have diversified into four primary categories: （ 1 ） Open-Air Storage Yards:  This involves storing coal resources outdoors, once the dominant choice for early coal enterprises but now largely phased out. （ 2 ） Semi-Open Storage Yards:  Also known as dry coal sheds, these are widely adopted by coal enterprises in southern China. Given the abundant rainfall in southern coal mining regions, this storage method—which combines protection with ventilati...

  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 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, live load...
