  Regulations and Methods for Considering Accidental Eccentricity Effects in Seismic Design in China, the United States and Europe 1. Regulatory Basis ● China The Code for Seismic Design of Buildings (GB 50011-2010) stipulates that accidental eccentricity must account for uncertainties in structural mass distribution, stiffness distribution, and spatial variations in seismic motion. Torsional effects shall be calculated using either static or dynamic methods. ● United States ASCE 7-22 (American Society of Civil Engineers Standard) requires consideration of accidental torsional effects, typically calculated using static methods, with verification through dynamic analysis results. ● Europe Eurocode 8 (EN 1998-1:2004) simulates the misalignment between mass centres and stiffness centres by introducing accidental eccentricity, and mandates consideration of the effects of bidirectional seismic actions . 2. Definition and Values of Random Eccentricity ● China Eccentricity: ±5% of the ...

 In the rapid advancement of modern industry, industrial buildings serve as the core spaces for production and storage. Their structural design must not only fulfil functional requirements but also balance safety, economy, efficiency, and sustainability. As a company consistently focused on environmental stewardship and dedicated to providing high-quality, safe, and robust steel structure designs and products globally, we recognise that space frame structures represent the ideal solution for achieving these comprehensive objectives in industrial building applications. Space frame structures comprise spatial grid systems formed by multiple members connected through nodes. Their unique load-bearing characteristics and geometric configurations offer exceptional advantages in industrial building construction: Achieving Extraordinary Spans: Industrial facilities frequently require expansive, column-free spaces to accommodate production line layouts, large-scale equipment installation...

The port of Pointe-Noire in the Central African Republic, situated on the Atlantic coast, serves as the nation's vital economic gateway. The region experiences a typical tropical maritime climate characterised by year-round high temperatures and humidity, abundant rainfall, and strong sea breezes. As a port area, the terrain is generally flat, though it may encounter issues with foundation bearing capacity and tidal influences. Pointe-Noire Given these climatic and topographical characteristics, the following preliminary steel structure design proposal aims to provide guidance for constructing storage warehouses at Black Point Port.   Why choose steel structures ? In environments such as Black Point Port, steel-framed storage warehouses offer distinct advantages: Efficient construction: Steel components can be prefabricated off-site and rapidly assembled on-site, significantly reducing the construction timeline. For port projects, this translates to faster operational readiness an...

In the construction of modern industrial buildings , steel structures have become the preferred choice for an increasing number of enterprises due to their unique advantages. Not only can they meet the demands for large spans and expansive spaces, but they also excel in construction efficiency, cost-effectiveness, and sustainability. Selecting the appropriate steel structure configuration is crucial to ensuring the functionality, safety, and economic viability of the building. 1. Portal Frame Structure Characteristics: A frame structure comprising solid or lattice steel columns and beams connected rigidly. Features a straightforward design with clear load transfer pathways. Advantages: Simple structure: Relatively straightforward to design and construct, facilitating standardisation. Rapid construction: Components are highly prefabricated in factories, enabling swift on-site assembly. Cost-effectiveness: Relatively low construction costs for medium-to-small span industrial buildings (t...

 In recent years, with the development of China's economy and the continuous advancement of science and technology, large-span steel structures of various forms have been widely used in public buildings such as sports venues, exhibition centers, theaters, large shopping malls, airports, and stations. In the industrial sector, large-span industrial plants, especially under the requirements of environmental protection policies, have seen significant application in the enclosure of various material yards in recent years. Large-span steel structures have entered a period of vigorous development. The concept of steel tube trusses A structure formed by a plane or three-dimensional truss composed of round or square (rectangular) tubes. Its axis is a two-dimensional curve (such as an arc, parabola, catenary, or ellipse), and it relies on the thrust of the tubular truss column feet to resist the action of loads in the plane. Steel tube truss structures , as a branch of large-span spatial s...
