  I. Design codes and loading requirements 💖1. Saudi Building Code (SBC 301) Core Parameters Seismic design: according to Class II site category, seismic acceleration of 0.25g, seismic force calculation using the equivalent lateral force method, the main structure displacement angle limit of 1/200. Wind load: basic wind pressure is 0.75kN/m² (100-year return period), equivalent wind pressure is 1.2kN/m² after considering height coefficient, local wind suction coefficient is 1.5. Snow load: reference to the historical data of Mecca area, the additional roof load is calculated as 0.5kN/m². 💖2. Functional space indicators 1.5000 people worship space needs main hall net area ≥ 3500m ² (calculated at 0.7m ² /person). 2.suggests a 45m x 80m rectangular plan, with a central dome 30m in diameter, flanked by wavy vaults.

 Large-span roof structures play a significant role in modern architecture, particularly in sports venues, exhibition centres, and industrial plants. Bolted spherical grid structures, as an efficient spatial grid structure, have gained widespread application in large-span roof projects due to their lightweight design, high load-bearing capacity, and ease of construction. I. Structural design features of bolted ball grid structures Bolted ball grid structures consist of ball nodes and members connected by bolts to form a three-dimensional spatial load-bearing system. Their structural design features the following characteristics:   Lightweight and high load-bearing capacity: The members of bolted ball grid structures are typically made of steel pipes or round bars with small cross-sectional dimensions, resulting in a lightweight overall structure. However, through reasonable member arrangement and node design, they can withstand significant loads. Convenient construction: The ...

  Welding is a cornerstone of steel building construction , ensuring structural integrity and longevity. Selecting the appropriate welding method is crucial, as it influences the strength, durability, and efficiency of the construction process. Below, we explore the most commonly used welding techniques in steel building projects.   1. Shielded Metal Arc Welding (SMAW) Also known as "stick welding," SMAW is one of the oldest and most versatile welding methods. It employs a consumable electrode coated with flux to create an electric arc between the electrode and the base metal. The flux coating disintegrates during welding, producing a shielding gas that protects the weld area from atmospheric contamination. Advantages: Versatility: Suitable for various positions, including overhead and vertical welding. Simplicity: Requires relatively simple equipment, making it accessible for many projects.     Adaptability: Effective for welding thick materials and can be used outd...

 Large-span roofs are a common structural form in modern buildings and are widely used in large-scale public buildings such as stadiums, exhibition centres and airport terminals. In these projects, the structural design should not only meet the functional requirements, but also take into account the economy, aesthetics and construction feasibility. As an efficient space grid structure, bolted ball space frame is widely used in large-span roofing projects due to its advantages of light dead weight, strong bearing capacity and convenient construction. I. Structural design characteristics of bolted ball grid frame Bolted ball mesh rack is a kind of three-dimensional space  structure composed of ball nodes and rods, and its core feature is to connect the rods and ball nodes through bolts to form an overall force system. Compared with traditional steel joist, bolted ball grid has the following structural design advantages: Light deadweight: the rods of bolted ball space struc...

Ever wondered how those colossal steel stadiums are built? This video takes you through the fascinating construction process, revealing the key stages involved in creating these impressive sporting arenas. From foundation to roof, see how steel structures come together to host world-class events.

 In China, seven buildings were designed with ‘bamboo shoots’ in mind. 1.The 57-metre-high landscape structure ‘ The First Shoot in the World ’ in Taojiang County, Hunan Province, consists of six curved structures similar to the shell of a bamboo shoot, wrapped in a mesh structure on the outside, with a glass curtain wall on the inside and a viewing platform. The building has multiple functions, including observation, forest fire prevention, communication and observation. The shape of the building is based on the imagery of ‘ spring shoots after rain ’ , breaking out of the ground and climbing upwards, symbolising strong, progressive and upward development. 2. China Resources Building Completed and opened in December 2018, China Resources Building, also known as ‘Spring Bamboo Shoots’, is located in the financial headquarters base in Houhai, Shenzhen, Guangdong Province. With a height of 392.5 metres and a total gross floor area of approximately 270,000 square metres, it is the thi...
