Project Challenges: Double Impact of Typhoons and Earthquakes The coal storage bunker of Power Plant in the Philippines has been facing tests from extreme natural conditions since the planning stage: Climate Challenge : Located in a super typhoon zone with wind speeds of up to 260 kilometers per hour, it withstands fierce storms and heavy rains every year. Geological Threat : Situated in a high seismic intensity zone with Z=0.4, the structural stability must be absolutely guaranteed. Cost Pressure : The client requires strict control over overseas construction costs while ensuring safety, and also demands controllable construction periods. Ultra-Large Scale : With a total height of 48.675 meters and a foundation height of 3.0 meters, the long-span dome design poses a great challenge to structural strength for industrial projects. Solutions: Comprehensive Upgrades from Design to Materials Targeting these pain points, our overseas engineering team has tailor-made a combined solu...

Application and Installation of Bolted Ball Grids in the Design of Large-Span Roof Structures

图片
 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...
